ADA4505-1 - Zero Input Crossover Distortion Amplifiers

General Description

The ADA4505-1/ADA4505-2/ADA4505-4 are single, dual, and quad micropower amplifiers featuring rail-to-rail input and output swings while operating from a single 1.8 V to 5 V power supply or from dual ±0.9 V to ±2.5 V power supplies.

Key Features

  • PSRR: 100 dB minimum CMRR: 105 dB typical Very low supply current: 10 μA per amplifier maximum 1.8 V to 5 V single-supply or ±0.9 V to ±2.5 V dual-supply operation Rail-to-rail input and output 3 mV offset voltage maximum Very low input bias current: 0.5 pA typical OUT 1 V.
  • 2 +IN 3 PIN.
