LTC1049 - Linear Technology

LTC1049 Low Power Chopper Stabilized Operational Amplifier

The LTC®1049 is a high performance, low power zero-drift operational amplifier. The two sample-and-hold capacitors usually required externally by other chopper stabilized amplifiers are integrated on the chip. Further, the LTC1049 offers superior DC and AC performance with a nominal supply current of only 200µA. The LTC1049 has a typical offset voltage of 2µ.
