Introduction

AI Translation

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

These amplifiers employ a new circuit topology that achieves zero input crossover distortion (excellent PSRR and CMRR performance) and ultralow bias current, with quiescent supply current below 10 µA per amplifier at low cost.

This combination of features makes the ADA4505-x amplifiers ideal for battery-powered applications, minimizing errors caused by supply voltage variations over battery life while maintaining high CMRR, even for rail-to-rail op amps.

Remote battery-powered sensors, handheld instruments and consumer electronics, hazard detectors (e.g., smoke, fire, gas), and patient monitors can all benefit from the features of the ADA4505-x amplifiers.

The ADA4505-x series is rated for the −40°C to +85°C industrial temperature range and the −40°C to +125°C extended industrial temperature range.
