The AD817 is a low cost, low power, single/dual supply, high speed op amp which is ideally suited for a broad spectrum of signal conditioning and data acquisition applications. This breakthrough product also features high output current drive capability and the ability to drive unlimited capacitive load.
The AD817 operational amplifier from Analog Devices offers a combination of high speed (50 MHz unity‑gain bandwidth) and low power consumption (7.5 mA quiescent current). It is available in 8‑pin plastic Mini‑DIP and SOIC packages and can operate from a single +5 V supply or dual supplies from ±5 V to ±15 V.
Its high output drive capability (minimum 50 mA, unlimited capacitive load) and low offset (≤2 mV) make it suitable for video, imaging, ADC buffering and high‑speed DAC applications. The datasheet includes typical characteristics, absolute maximum ratings, and application notes on driving capacitive loads, offset nulling, and grounding/bypassing techniques.
