The LTC1150CN8#PBF is a ±15V zero-drift Operational Amplifier with internal capacitors. The two sample-and-hold capacitors usually required externally by other chopper amplifiers are integrated on-chip. Further proprietary high-voltage CMOS structures allow the LTC1150 to operate at up to 32V total supply voltage. The LTC1150 has an offset voltage of 0.5µV, drift of 0.01µV/°C, 0.1 to 10Hz input noise voltage of 1.8µVP-P and a typical voltage gain of 180dB. The slew rate of 3V/µs and a gain bandwidth product of 2.5MHz are achieved with 0.8mA of supply current. Overload recovery times from positive and negative saturation conditions are 3 and 20ms, respectively. For applications demanding low power consumption, pin 1 can be used to program the supply current. Pin 5 is an optional AC-coupled clock input, useful for synchronization. It is plug in replacement for most standard bipolar operational amplifier with improved DC performance.
