Precision Zero-Drift Operational Amplifier with Internal Capacitors DESCRIPTIO 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-andhold capacitors usually required externally by other chopper amplifiers. Further, the LTC1050 offers better bined overall DC and AC performance than is available from 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 1.6µVP-P and a typical voltage gain of 160d B. The slew rate of 4V/µs and a gain bandwidth product of 2.5MHz are achieved with only 1m A 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 external capacitors. Pin 5 is an optional external clock input, useful for synchronization purposes. 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 can be an improved plug-in replacement for most standard op...
