The wide input common-mode range is achieved with a high frequency on-board charge pump. This technique eliminates the crossover distortion and limited CMRR imposed by com- peting technologies. The LTC1152 is a C-Load TM of amp, enabling it to drive any capacitive load. The LTC1152 shares the excellent DC performance specs of LTC’s other zero-drift amplifiers. Typical offset voltage is 1 µV and typical offset drift is 10nV/°C. CMRR and PSRR are 130dB and 120dB and open-loop gain is 130dB. Input noise voltage is 2 µVP-P from 0.1Hz to 10Hz. Gain-band- width product is 0.7MHz and slew rate is 0.5V/ µs, all with supply current of 3.0mA max over temperature. The LTC1152 also includes a shutdown feature which drops supply current to 1 µA and puts the output stage in a high impedance state. The LTC1152 is available in 8-pin PDIP and 8-pin SO packages and uses the standard op amp pinout, allowing it to be a plug-in replacement for many standard op amps. 5V 0V 1152 TA02 Input and Output Waveforms Rail-to-Rail Buffer VOUT 2V/DIV 0V 5V VIN 2V/DIV APPLICATI TYPICAL , LTC and LT are registered trademarks of Linear Technology Corporation.
