LTC1049
Low power zero-drift op amp with internal capacitors
peculiarity
description
The LTC1049 is a high performance, low power zero-drift operational amplifier.The LTC1049 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.Integrating two sample-and-hold on-chip typically requires additional chopper-stabilized amplifier external capacitors. Further, the LTC1049 offers superior DC and AC performance with a nominal supply current of only 200µA.In addition, the 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 3µVPPand typical voltage gain of 160dB.The LTC1049 has a 2μV drift between 0.02μV/°C and is an input noise voltage from a typical offset voltage of 0.1Hz to 10Hz3μVPPand a typical voltage gain of 160 dB. The slew rate is 0.8V/µs with a gain bandwidth product of 0.8MHz.The slew rate is 0.8V/μs with a gain bandwidth of 0.8MHz.
Overload recovery time from a saturation condition is 6ms, a significant improvement over chopper amplifiers using external capacitors.The overload recovery time from saturation conditions is 6ms, and the chopper amplifier uses an external capacitor, which is significantly improved.
The LTC1049 is available in a standard 8-pin plastic dual in line, as well as an 8-pin SO package.The LTC1049 is available in standard-compliant 8-lead plastic dual and 8-lead SO packages. The LTC1049 can be a plug-in replacement for most standard op amps with improved DC performance and substantial power savings.The LTC1049 can be a plug-in replacement for improved DC performance and considerable power accumulation of the most standard op amp.
