LTC1050 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 combined 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 160dB. 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 fr...
