The AD820ARMZ from Analog Devices Inc. is a precision operational amplifier that combines the best of both worlds: FET inputs and rail-to-rail output swing. This single-supply amplifier is designed to deliver high performance while consuming minimal power, making it an ideal choice for battery-powered applications and portable devices.

Key Features

• Low Power Consumption: The AD820ARMZ operates with a supply current of just 800 µA max, which is excellent for power-sensitive applications.
• FET Input: The FET input provides low input bias currents (100 pA max), making it suitable for high impedance sensor amplification and precision integrators.
• Rail-to-Rail Output: The amplifier can swing to within millivolts of each rail, providing the maximum output dynamic range which is especially beneficial in single-supply operations.
• Wide Supply Voltage Range: It can operate from a single supply of 3 V to 36 V or dual supplies of ±3 V to ±18 V, offering flexibility in various circuit configurations.
• Low Offset Voltage: The offset voltage is only 1 mV max, which is ideal for precision applications.
• Unity-Gain Stable: The device is stable with capacitive loads of up to 10 pF, ensuring reliable performance in a feedback loop.
