evaluates: max1407/max1408/max1409/max1414 max1407 evaluation kit/evaluation system 6 _______________________________________________________________________________________ overview of software the max1407 ev software is configured as a series ofcontrol panels that include related groups of features. the following control panels are available: adc, dac, system, clock, registers, scripting, and block diagram. there is also an adc graph panel for plotting adc results vs. time. panels are selected by clicking their respective tab at the top. general control features such as selecting a specific device (max1407/ max1408/max1409/max1414) are available in a menu bar at the top of the window. help is available through the block diagram tab, the top menu bar, or by press- ing f1 (panel-specific help). an image and brief description of each control panel is given in the following sections. adc control panel the adc control panel provides access to the 16-bit,sigma-delta a/d converter, programmable-gain amplifier (pga), adc buffers, analog input multiplexers, and signal-detect comparator (figure 2). dac control panel the dac control panel provides access to the internalvoltage reference, as well as the 10-bit dacs (where available) (figure 3). system control panel the system control panel provides access to the twowakeup inputs, assorted logic output signals, power modes, v dd , and reset voltage monitors, and the max5154 dual dacs present on the max1407 ev kit(figure 4). clock control panel the clock control panel provides access to the rtcand the alarm. the pc system time is also shown to enable easy comparison with the max1407 rtc (figure 5). registers control panel the registers control panel allows read and writeaccess to the max1407 control registers (figure 6). scripting control panel the scripting control panel provides a facility to exe- cute simple script programs that run a sequence of actions with the max1407 ev system. this allows users to experiment with max1407 features under precise timing control without having to write firmware in c, c++, or assembly language (figure 7). block diagram display panel the block diagram display panel allows quick accessto the block diagram of the part currently selected in the device pulldown menu (max1407, max1408, max1409, or max1414). one-button access to the max1407 data sheet is also provided for user conve- nience (figure 8). adc graph display panel the adc graph display panel allows x-y plotting ofadc conversion data or derived parameters vs. time. the adc, mux, and plot display settings can all be adjusted within the adc graph display panel. one or more adc graph display panels can be opened from the adc control panel using the adc graph button (figure 9). detailed description of hardware the max1407 (u1) is a multichannel, 16-bit das withinternal reference, dual 10-bit dacs, and other system support functions. all support circuitry required by the max1407, including decoupling capacitors and a 32khz crystal, are included in the ev kit board layout. external circuitry can be added in the prototype area to configure the adc input signals, as well as the force/sense dacs. the max1833 (u2) is an inductor- based power supply that can be used to battery power the max1407. the 74lvc244a (u3) is used to level shift +5v logic input signals from the 80c32 module down to the max1407 supply voltage rails (+1.8v to +3.6v). the max978 comparators (u4 and u5) are logic-level translators between the max1407 (+1.8v to +3.6v) and the 80c32 ? module (+5v). the max8863 linear regulator (u6), max6162 voltage reference (u7), and max5154 dac (u8) are combined to create a pro- grammable v dd power supply for the max1407. when plugged into the 80c32module, the programmablepower supply for the max1407 is derived from the 80c32 ? module? +5v supply, and no additional power-supply connections are needed. see figure 10, and refer to the max1407/max1408/max1409/ max1414 data sheet. evaluating the max1408, max1409, or max1414 the max1408 or max1414 can be soldered directly inthe 28-pin ssop footprint normally occupied by the max1407. the max1414 pins have the same functions as the max1407, with the main difference being the 50mv offset of the max1414? internal signal detect comparator. when a max1408 is inserted, the upper four analog inputs (ain4, ain5, ain6, and ain7) corre- downloaded from: http:///

(1 + r2 / r1) (n dac1/2 is the max1407 dac1/dac2 code word between zero and 1023 decimal. v ref is the voltage at the ref pin coming from the internal or an external+1.25v reference.) care must be taken to ensure the voltage at the out1/out2 pin is not saturating as it approaches the av dd rail. the max1409 has one force/sense dac and the max1408 has no dacs. notethe ev software assumes the dacs have an ideal +1.25v reference voltage, but an actual, measured value can be entered to display more accurate dac voltages on the dac control panel. analog inputs the max1407/max1414 each have 4 pins (in0?n3)that allow users to drive differential or single-ended analog voltages directly into either adc input, in buffered or unbuffered mode. the max1409 has a sin- gle analog input (in0) and the max1408 has eight ana- log inputs (in0?n7). there is no lowpass filtering of the analog inputs on the ev kit board. users should take precautions to avoid undesired noise in narrow bands around the adc input sampling frequencies (15.36khz or 30.72khz plus harmonics, refer to the max1407/ max1408/max1409/max1414 data sheet). wakeup input switches there are two switches (sw1 and sw2) on the ev kitboard that connect directly to the wu1 and wu2 wake- up input pins on the max1407/max1408/max1409/max1414. when the max1407/max1408/max1409/ max1414 are in sleep mode, closing either switch wakes the part up in standby mode, enables the pll, fout pin, low v dd monitor, and drives the shdn pin (except on max1409) high. switch closures are alsoreflected by the green leds on the system control panel of the ev software. a pair of buttons on the system control panel provides equivalent software con- trol of the wu1 and wu2 wakeup inputs. programmable power-supply voltage a programmable power supply controlled by the 12-bit,max5154? dac a is provided to simplify evaluation of the max1407/max1408/max1409/max1414 functions vs. v dd supply voltage. this is especially convenient when testing threshold voltages on the two voltagemonitors. the power-supply voltage can be software controlled from the system control panel of the ev soft- ware. the nominal v dd voltage is programmed by the following equation: v dd = 3.7479 - 0.0004983389 ? n daca (n daca is the max5154? dac a code word between zero and 4095 decimal.) this provides an approximatev dd range of 1.71v to 3.75v in 0.5mv steps, although the actual value varies because of tolerances and othernonidealities. the power-on default value is close to 3.0v. note the ev software assumes the dac has an ideal 2.048v reference voltage, but an actual, mea- sured value can be entered on the system control panel to display a more accurate v dd voltage. powering from a max1833 power supply and batteries a max1833 inductor-based power supply is included inthe ev kit, allowing users to battery power the max1407/max1408/max1409/max1414 from 2 alkaline cells, or 1 lithium-ion (li+) cell, and evaluate the following system-level features: power-supply shutdown control through themax1407/max1408/max1414 shdn pin sleep-mode operation of the max1407/max1408/max1409/max1414 through the shorted pfet switch inside the disabled max1833 (i.e., running directly from the batteries) power-supply switching transient impact on themax1407/max1408/max1409/max1414 functions such as adc output noise downloaded from: http:///
