ADA4077-4 Datasheet

ADA4077-4 High Precision Amplifiers

The single ADA4077-1, dual ADA4077-2, and quad ADA4077-4 amplifiers feature extremely low offset voltage and drift, and low input bias current, noise, and power consumption. Outputs are stable with capacitive loads of more than 1000 pF with no external compensation. Applications for this amplifier i.
