Overview of AD822ARZ by Analog Devices Inc.
The AD822ARZ is a single-supply, rail-to-rail, low power, FET-input dual operational amplifier, designed and manufactured by Analog Devices Inc. This operational amplifier stands out because of its capability to operate from a single power supply over a wide range of voltages, which is crucial for battery-powered devices. The rail-to-rail input and output feature allows the amplifier to utilize the full voltage range available from the power supply, maximizing signal dynamic range. Packaged in an 8-pin SOIC with a RoHS-compliant MS-012AA, this component features a low input bias current (0.005 µA max), making it an excellent choice for high-impedance sensor applications and precision integrators.
The AD822ARZ’s operational amplifier is built on a voltage-feedback architecture enhancing stability and simplifying feedback loop design. It boasts a nominal common-mode rejection ratio (CMRR) of 80 dB, mitigating the effect of common-mode noise on signal integrity. With its low power consumption (micropower technology) and a maximum supply current of 1.8 mA, it is an ideal selection for energy-sensitive projects. Additionally, its operational temperature range from -40 °C to 85 °C qualifies it for use in a vast array of industrial environments.
This amplifier’s performance is further characterized by its nominal unity gain bandwidth of 1900 kHz and a slew rate of 3 V/µs, providing a good balance between speed and power consumption. Its low offset voltage (maximum of 3000 µV) and the ability to be powered by up to ±18 V make it versatile for a broad spectrum of applications, from automated test equipment to sensor interfacing and signal conditioning.
