7 LT1815 applicatio s i for atio wu uu layout and passive components as with all high speed amplifiers, the LT1815 requires some attention to board layout. a ground plane is recom- mended and trace lengths should be minimized, especially on the negative input lead. low esl/esr bypass capacitors should be placed directly at the positive and negative supply (0.01 m f ceramics are recommended). for high drive current applications, addi- tional 1 m f to 10 m f tantalums should be added. the parallel combination of the feedback resistor and gain setting resistor on the inverting input combine with the input capacitance to form a pole that can cause peaking or even oscillations. if feedback resistors greater than 1k are used, a parallel capacitor of value, c f > r g ? c in /r f should be used to cancel the input pole and optimize dynamic performance. for applications where the dc noise gain is 1 and a large feedback resistor is used, c f should be greater than or equal to c in . an example would be an i-to-v converter. input considerations the inputs of the LT1815 amplifier are connected to the base of an npn and pnp bipolar transistor in parallel. the base currents are of opposite polarity and provide first- order bias current cancellation. due to variation in the matching of npn and pnp beta, the polarity of the input bias current can be positive or negative. the offset current, however, does not depend on beta matching and is tightly controlled. therefore, the use of balanced source resis- tance at each input is recommended for applications where dc accuracy must be maximized. for example, with a 100 w source resistance at each input, the 800na maxi- mum offset current results in only 80 m v of extra offset, while without balance the 8 m a maximum input bias cur- rent could result in a 0.8mv offset contribution. the inputs can withstand differential input voltages of up to 6v without damage and without needing clamping or series resistance for protection. this differential input voltage generates a large internal current (up to 80ma), which results in the high slew rate. in normal transient closed-loop operation, this does not increase power dissipation significantly because of the low duty cycle of the transient inputs. sustained differential inputs, how- ever, will result in excessive power dissipation and there- fore this device should not be used as a comparator . capacitive loading the LT1815 is stable with capacitive loads from 0pf to 100pf, which is outstanding for a 220mhz amplifier. the internal compensation circuitry accomplishes this by sens- ing the load induced output pole and adding compensation at the amplifier gain node as needed. as the capacitive load increases, both the bandwidth and phase margin de- crease, so there will be peaking in the frequency domain and ringing in the transient response. coaxial cable can be driven directly, but for best pulse fidelity, a resistor of value equal to the characteristic impedance of the cable (e.g. 75 w ) should be placed in series with the output. the receiving end of the cable should be terminated with the same value resistance to ground. slew rate the slew rate of the LT1815 is proportional to the differen- tial input voltage. therefore, highest slew rates are seen in the lowest gain configurations. for example, a 5v output step in a gain of 10 has a 0.5v input step, whereas in unity gain there is a 5v input step. the LT1815 is tested for a slew rate in a gain of C 1. lower slew rates occur in higher gain configurations. programmable current and shutdown (6-lead sot-23 only) the LT1815s6 has an enable pin (en, pin 5), which is referenced to the negative supply and has an active low polarity. in order to operate the LT1815s6 at full speed (and full supply current), pull the en pin down to the negative supply through an on-resistance of 75 w or less.
8 LT1815 to adjust or program the supply current and speed of the LT1815s6, connect an external resistor (r en ) between the en pin and the negative supply as shown in figure 1. in this low power mode the amplifier is fully functional. figures 2 and 3 show how the gain bandwidth and supply current vary with the value of the programming resistor r en . when the en pin is left unconnected or is forced at least 2v above the negative supply voltage, the LT1815s6 is in shutdown mode and draws only 150 m a of supply current. the amplifier output is not isolated from the inputs, however, so the shutdown feature must not be used for multiplexing applications. power dissipation the LT1815 combines high speed and large output drive in a small package. however, the junction temperature will not exceed the 150 c maximum unless the part is used outside of its specified drive capability. maximum junction temperature (t j ) is calculated from the ambient tempera- ture (t a ) and power dissipation (p d ) as follows: t j = t a + (p d ? q ja ) (note 9) power dissipation is composed of two parts. the first is due to the quiescent supply current and the second is due to on-chip dissipation caused by the load current. the worst-case load induced power occurs when the output voltage is at 1/2 of either supply voltage (or the maximum swing if less than 1/2 the supply voltage). therefore p dmax is: p dmax = (v + C v C ) ? (i smax ) + (v + /2) 2 /r l or p dmax = (v + C v C ) ? (i smax ) + (v + C v omax ) ? (v omax /r l ) example: LT1815cs5 at 70 c, v s = 5v, r l =100 w p dmax = (10v) ?

9 LT1815 circuit operation the LT1815 circuit topology is a true voltage feedback amplifier that has the slewing behavior of a current feed- back amplifier. the operation of the circuit can be under- stood by referring to the simplified schematic. complementary npn and pnp emitter followers buffer the inputs and drive an internal resistor. the input voltage appears across the resistor generating current that is mirrored into the high impedance node. complementary followers form an output stage that buff- ers the gain node from the load. the input resistor, input stage transconductance, and the capacitor on the high impedance node determine the bandwidth. the slew rate is determined by the current available to charge the gain node capacitance. this current is the differential input voltage divided by r1, so the slew rate is proportional to applicatio s i for atio wu uu the input step. highest slew rates are therefore seen in the lowest gain configurations. the rc network across the output stage is bootstrapped when the amplifier is driving a light or moderate load and has no effect under normal operation. with a heavy load (capacitive or resistive), the network is incompletely bootstrapped and adds to the compensation at the high impedance node. the added capacitance moves the unity- gain frequency away from the pole formed by the output impedance and the capacitive load. the zero created by the rc combination adds phase to ensure that the total phase lag does not exceed 180 (zero phase margin) and the amplifier remains stable. in this way, the LT1815 is stable with up to 100pf capacitive loads in unity gain, and even higher capacitive loads in higher closed-loop gain configurations. si plified sche atic ww 1815 ss out +in ?n bias control v + v 6-lead sot-23 only en r1 c c r c c
