DESCRIPTION
The LTC®1150 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.
