AD823ARZ-R7 Dual rail-to-rail operational amplifier 2 Circuit 8MHz GBW
The AD823ARZ-R7 is a precision, low power dual operational amplifier from Analog Devices, designed for high-performance signal conditioning in industrial, medical, and instrumentation applications. This rail-to-rail output op-amp operates from ±1.5V to ±18V dual supplies or +3V to +36V single supply, delivering excellent DC precision with low input offset voltage (250µV max) and ultra-low input bias current (1nA max). The device features 8MHz gain-bandwidth product and 16V/µs slew rate, making it ideal for active filters, precision integrators, and sensor interfaces where both speed and accuracy are critical. Its low power consumption (750µA per amplifier) and wide temperature range (-40°C to +125°C) ensure reliable operation in demanding environments, while the 8-pin SOIC package offers space-efficient implementation for portable and high-density designs.
AD823ARZ-R7 Applications
This operational amplifier is extensively used in medical instrumentation, particularly for ECG front-ends and patient monitoring systems where its low noise and high CMRR are critical. In industrial automation, it serves in 4-20mA transmitter loops, RTD/thermocouple conditioning, and bridge sensor interfaces. The AD823ARZ-R7 excels in test and measurement equipment such as spectrum analyzers and lock-in amplifiers requiring precision signal paths. Audio applications benefit from its low distortion (0.0003% at 1kHz), while battery-powered systems leverage its low power consumption for extended operation. The device is also deployed in aerospace systems for critical signal conditioning, and in scientific instrumentation where its DC precision enables accurate low-level measurements.
