detailed description the max5391/max5393 dual 256-tap, volatile, low- voltage linear taper digital potentiometers offer three end- toend resistance values of 10k, 50k, and 100k. each potentiometer consists of 255 fixed resistors in series between terminals h_ and l_. the potentiometer wiper, w_, is programmable to access any one of the 256 tap points on the resistor string. the potentiometers in each device are programmable independently of each other. the max5391/max5393 feature an spi interface. charge pump the max5391/max5393 contain an internal charge pump that guarantees the maximum wiper resistance, r wl , to be less then 200 for supply voltages down to 1.7v. pins h_, w_, and l_ are still required to be less than v dd + 0.3v. a bypass input, byp, is provided to allow additional filtering of the charge-pump output, further reducing clock feed through that may occur on h_, w_, or l_. the nomi - nal clock rate of the charge pump is 600khz. byp should remain resistively unloaded as any additional load would produce a ripple of approximately i byp /(600khz x c byp ) volts. see the charge-pump feedthrough at w_ vs. c byp graph in the typical operating characteristics for c byp sizing guidelines with respect to clock feedthrough to the wiper. the value of c byp does affect the startup time of the charge pump; however, c byp does not impact the ability to communicate with the device, nor is there a minimum c byp requirement. the maximum wiper imped - ance specification is not guaranteed until the charge pump is fully settled. see the byp ramp vs. c byp graph in the typical operating characteristics for c byp impact on charge-pump settling time. spi digital interface the max5391/max5393 include a spi interface that pro - vides a 3-wire write-only serial-data interface to control the wiper tap position through inputs chip select ( cs ), data in (din), and data clock (sclk). drive cs low to load data from din synchronously into the serial shift register on the rising edge of each sclk pulse. the max5391/ max5393 load the last 10 bits of clocked data into the appropriate potentiometer control register once cs transi - tions high. see figures 2 and 3. data written to a memory register immediately updates the wiper position. keep cs low during the entire data stream to prevent the data from being terminated. the first two bits a1:a0 (address bits) address one of the two potentiometers. see table 1. the power-on reset (por) circuitry sets the wiper to midscale. figure 2. spi digital interface format table 1. spi register map bit number 1 2 3 4 5 6 7 8 9 10 bit name a1 a0 d7 d6 d5 d4 d3 d2 d1 d0 write wiper register a 0 0 d7 d6 d5 d4 d3 d2 d1 d0 write wiper register b 0 1 d7 d6 d5 d4 d3 d2 d1 d0 write to both a and b 1 1 d7 d6 d5 d4 d3 d2 d1 d0 cs command started 10-bit sclk din a0 a1 d7 d6 d5 d4 d3 d2 d0 d1 wiper register loaded max5391/max5393 dual 256-tap, volatile, low-voltage linear taper digital potentiometers www.maximintegrated.com maxim integrated 9 downloaded from: http:///
