AD826ARZ-REEL7

The AD826ARZ-REEL7 is a dual high-speed voltage-feedback operational amplifier from Analog Devices, offering 50 MHz bandwidth and 350 V/us slew rate in a compact SOIC-8 package. Each amplifier delivers a minimum of 50 mA output current and can drive unlimited capacitive loads, making it ideal for demanding buffer and cable driving applications. The device operates from a single +5V supply (achieving 25 MHz bandwidth) up to +/-15V dual supplies, providing flexibility for a wide range of signal chain applications.

The AD826 uses a voltage-feedback architecture with a high-transconductance input stage driving a push-pull output stage. The internal compensation provides unity-gain stability while maintaining high bandwidth. The output stage delivers 50 mA minimum with low output impedance, enabling it to drive heavy loads including cables and low-impedance terminations. The device’s ability to drive unlimited capacitive loads is achieved through an internal compensation network that prevents oscillation under heavy capacitive loading conditions.
