  The LTC®1050 is a high performance, low cost zero-drift operational amplifier. The LTC®1050 is a high-performance, low-cost, zero-drift op-amp. The unique achievement of the LTC1050 is that it integrates on-chip the two sample-and-hold capacitors usually required externally by other chopper amplifiers. LTC1050 unique achievement is that it integrates two samples on the chip and holds external capacitors that are often required for other chopper amplifiers. Further, the LTC1050 offers better combined overall DC and AC performance than is available from other chopper stabilized amplifiers with or without internal sample-and-hold capacitors. In addition, LTC1050 provides better combined overall DC and AC performance than other chopper-stabilized amplifiers, with or without internal sampling and holding capacitors.

  The LTC1050 has an offset voltage of 0.5µV, drift of 0.01µV/°C, DC to 10Hz, input noise voltage of 1.6µV PP and a typical voltage gain of 160dB. LTC1050 has an offset voltage of 0.5μV, drift of 0.01μV/°C, DC to 10Hz, input noise voltage, 1.6μVPP and a typical voltage gain of 160 dB. The slew rate of 4V/μs and a gain bandwidth product of 2.5MHz are achieved with only 1mA of supply current.

  Overload recovery times from positive and negative saturation conditions are 1.5ms and 3ms respectively, which represents an improvement of about 100 times over chopper amplifiers using The overload recovery time from positive and negative saturation conditions is 1.5ms for 3ms respectively, and the chopper amplifier uses external capacitors, which represent an improvement of about 100x. Pin 5 is an optional external clock input, useful for synchronization purposes. The 5-pin pin is an optional external clock input that is useful for synchronization.

  The LTC1050 is available in standard 8-pin metal can, plastic and ceramic dual-in-line packages as well as an SO-8 package. LTC1050 is available in standard 8-pin metal, plastic, and ceramic dual in-line packages as well as SO-8 packages. The LTC1050 can be an improved plug-in replacement for most standard op amps. LTC1050 plug-ins that can be improved can be replaced with the most standard op-amps.
