LTC1049 Low Power Zero-Drift Operational Amplifier with Internal Capacitors Fea T Descrip T n Low Supply Current: 200A The LTC 1049 is a high performance, low power zero-drift n No External Components Required operational amplifier. The two sample-and-hold capacitors n Maximum Offset Voltage: 10V usually required externally by other chopper stabilized n Maximum Offset Voltage Drift: 0.1V/C amplifiers are integrated on the chip. Further, the LTC1049 n Single Supply Operation: 4.75V to 16V offers superior DC and AC performance with a nominal n Input Common Mode Range Includes Ground supply current of only 200A. n Output Swings to Ground The LTC1049 has a typical offset voltage of 2V, drift of n Typical Overload Recovery Time: 6ms 0.02V/C, 0.1Hz to 10Hz input noise voltage of 3V P-P n Available in 8-Pin SO and PDIP Packages and typical voltage gain of 160dB. The slew rate is 0.8V/s with a gain bandwidth product of 0.8MHz. a T Overload recovery time from a saturation condition is 6ms, a significant improvement over chopper amplifiers n 4mA to 20mA Current Loops using external capacitors. n Thermocouple Amplifiers n Electronic Scales The LTC1049 is available in a standard 8-pin plastic dual n Medical Instrumentation in line, as well as an 8-pin SO package. The LTC1049 can n Strain Gauge Amplifiers be a plug-in replacement for most standard op amps with n High Resolution Data Acquisition improved DC performance and substantial power savings.
