The LTC1150 is a high-voltage, high-performance zero-drift operational amplifier. The two sample-and-hold capacitors usually required externally by other chopper amplifiers are integrated on-chip. Further, LTC’s 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, 0.1Hz 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 productof 2.5MHz are achieved with 0.8mA of supply current. Overload recovery times from positive and negative saturation conditions are 3ms 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.
The LTC1150 is available in standard 8-lead, plastic dual-in-line package, as well as an 8-lead SO package. The LTC1150 can be a plug-in replacement for most standard bipolar op amps with significant improvement in DC performance.
