LTC1052/LTC7652 Zero-Drift Operational Amplifier
FEATURES DESCRIPTIO Guaranteed Max Offset: 5µV The LTC®1052 and LTC7652 are low noise zero-drift op Guaranteed Max Offset Drift: 0.05µV/°C amps manufactured using Linear Technology’s enhanced Typ Offset Drift: 0.01µV/°C LTCMOSTM silicon gate process. Chopper-stabilization Excellent Long Term Stability: 100n V/√Month constantly corrects offset voltage errors. Both initial offset Guaranteed Max Input Bias Current: 30p A and changes in the offset due to time, temperature and Over Operating Temperature Range: common mode voltage are corrected. This, coupled with Guaranteed Min Gain: 120d B picoampere input currents, gives these amplifiers Guaranteed Min CMRR: 120d B unmatched performance. Guaranteed Min PSRR: 120d B
