LT1797 10MHz, Rail-to-Rail Input and Output Op Amp in SOT-23 Fea T Descrip T n Rail-to-Rail Input and Output The LT 1797 is a unity-gain stable 10MHz op amp available n Small SOT-23 Package in the small SOT-23 package that operates on all single n Gain Bandwidth Product: 10MHz and split supplies with a total voltage of 2.7V to 12V. The n 40C to 85C Operation amplifier draws 1mA of quiescent current and has a slew n Slew Rate: 2.25V/s rate of 2.25V/s. n Low Input Offset Voltage: 1.5mV Max The input common mode range of the LT1797 includes n High Output Current: 25mA Min both rails, making it ideal for current sensing applications. n Specified on 3V, 5V and 5V Supplies The input stage incorporates phase reversal protection n High Voltage Gain: 1000V/mV 10k Load to prevent false outputs from occurring when the inputs n High CMRR: 96dB Typ are driven beyond the supplies. Protective resistors are n High PSRR: 90dB Typ included in the input leads so that current does not become n Input Bias Current: 300nA Max excessive when the inputs are forced above or below the n Input Offset Current: 25nA Max supplies. n Low Profile (1mm) SOT-23 (ThinSOT) Package + The output of the LT1797 can swing to within 50mV of V and 8mV of V without drawing excess current in either a T condition. The amplifier can drive loads up to 25mA and still maintain rail-to-rail capability. n Portable Instrumentation n Rail-to-Rail Buffer Amplifiers The LT1797 op amp is available in the space saving 5-lead n Low Voltage Signal Processing SOT-23 package. n Driving A/D Converters L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and ThinSOT and Over-The-Top are trademarks of Analog Devices, Inc.
