LTC1051/LTC1053 Dual/Quad Precision Zero-Drift Operational Amplifiers With Internal Capacitors DESCRIPTIO The LTC®1051/LTC1053 are high performance, low cost dual/quad zero-drift operational amplifiers. The unique achievement of the LTC1051/LTC1053 is that they integrate on chip the sample-and-hold capacitors usually required externally by other chopper amplifiers. Further, the LTC1051/LTC1053 offer better bined overall DC and AC performance than is available from other chopper stabilized amplifiers with or without internal sample/hold capacitors. The LTC1051/LTC1053 have an offset voltage of 0.5µV, drift of 0.01µV/°C, DC to 10Hz, input noise voltage typically 1.5µVP-P and typical voltage gain of 140d B. The slew rate of 4V/µs and gain bandwidth product of 2.5MHz are achieved with only 1m A of supply current per op amp. Overload recover times from positive and negative saturation conditions are 1.5ms and 3ms respectively, about a 100 or more times improvement over chopper amplifiers using external capacitors. The LTC1051 is available in an 8-lead standard plastic dual-in-line package as well as a 16-pin SW package. The LTC1053 is available in a standard 14-pin plastic package and an 18-pin SO. The LTC1051/LTC1053 are plug in replacements for most standard dual/quad op amps with improved performance.
