LTC1049
Low-power zero-drift op-amp with internal capacitors
peculiarity
description
The LTC1049 is a high performance, low power zero-drift operational amplifier. LTC1049 is a high-performance, low-power, zero-drift op-amp. 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. In addition, LTC1049 offers superior DC and AC performance with a nominal supply current of only 200μA.
The LTC1049 has a typical offset voltage of 2µV, drift of 0.02µV/°C, 0.1Hz to 10Hz input noise voltage of 3µV PP and typical voltage gain of 160dB. LTC1049 has a 0.02μV/°C intermediate 2μV, drift, 0.1Hz typical offset voltage to 10Hz input noise voltage 3μVPP and 160dB typical voltage gain. The slew rate is 0.8V/μs with a gain bandwidth product of 0.8MHz.
Overload recovery time from a saturation condition is 6ms, a significant improvement over chopper amplifiers using external capacitors.
The LTC1049 is available in a standard 8-pin plastic dual in line, as well as an 8-pin SO package. LTC1049 are standard-compliant 8-pin plastic duals, as well as 8-pin SO packages. The LTC1049 can be a plug-in replacement for most standard op amps with improved DC performance and substantial power savings. LTC1049 can be a plug-in replacement for the most standard operational amps with improved DC performance and considerable accumulated power.
