Key Features
- Ultra-low FET input bias current of 25 pA at 25°C minimizes input loading errors in high-impedance sensor and precision measurement circuits
- True rail-to-rail output swing on a single supply enables operation in battery-powered and low-voltage systems down to the supply rails
- 80 dB typical common-mode rejection ratio (CMRR) with internal frequency compensation ensures stable operation in low-noise signal conditioning applications
Applications
The AD822ARZ is ideal for precision signal conditioning of high-impedance sensors such as photodiodes, piezoelectric transducers, and pH electrodes in portable instrumentation and medical devices. Its single-supply rail-to-rail operation and low quiescent current make it well suited for battery-operated data acquisition systems, active filters, and transimpedance amplifier designs.

Frequently Asked Questions
What is the input bias current of the AD822ARZ?
The AD822ARZ has an extremely low maximum input bias current of 25 pA (0.000025 µA) at 25°C, with an average maximum of 5 nA. This FET-input characteristic makes it ideal for high-impedance sensor interfaces such as photodiode transimpedance amplifiers and electrochemical sensor circuits where input loading must be minimized.
What is the CMRR of the AD822ARZ?
The AD822ARZ achieves a common-mode rejection ratio (CMRR) of 80 dB typical and 66 dB minimum. This high CMRR is critical for rejecting common-mode noise and interference in differential signal acquisition applications, such as instrumentation front ends and sensor bridge amplifiers.
Can the AD822ARZ operate from a single supply?
Yes, the AD822ARZ is designed for single-supply operation and provides rail-to-rail output swing, allowing the output to swing close to both the positive and negative supply rails. This makes it suitable for 3 V, 3.3 V, and 5 V single-supply systems commonly found in portable and battery-operated instruments.
What package is the AD822ARZ available in?
The AD822ARZ comes in an 8-pin SOIC (Small Outline IC) surface-mount package with the manufacturer code R-8. This compact SMD package is suitable for automated PCB assembly and is widely available from Analog Devices authorized distributors. Note that this specific part number does not carry a Pb-free designation.
