  The LTC®1050 is a high performance, low cost zero-drift operational amplifier.The LTC®1050 is a high performance, low cost zero-drift operational amplifier. 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.The LTC1050's unique achievement is that it integrates two on-chip sample and hold other chopper amplifiers, which typically require external capacitors. 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, the LTC1050 offers a better combination of overall DC and AC performance than other chopper-stabilized amplifiers, with or without internal sample-and-hold capacitors.

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

  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 external capacitors.The overload recovery time from positive and negative saturation conditions is 1.5ms at 3ms respectively, and the chopper amplifier uses an external capacitor, which represents a approximately 100-fold improvement. Pin 5 is an optional external clock input, useful for synchronization purposes.Pin 5 is an optional external clock input 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.The LTC1050 is available in standard 8-lead 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.The LTC1050 can be replaced with the most standard op amp with an improved plug-in.
