Overview
The ADA4505-4ARUZ from Analog Devices Inc. is a quad micropower operational amplifier featuring rail-to-rail input and output swings. This CMOS amplifier is designed to operate from a single 1.8 V to 5 V power supply or from dual ±0.9 V to ±2.5 V power supplies. It is part of the ADA4505-x family, which is known for its zero crossover distortion, high power supply rejection ratio (PSRR), and common-mode rejection ratio (CMRR). This makes it ideal for applications requiring low power consumption and high signal integrity.
