The AD8397 is a dual operational amplifier from Analog Devices. It has a wide supply range (3V to 24V), high linear output current (310mA peak), low noise (4.5nV /√Hz voltage noise density@100kHz) and high speed (69MHz bandwidth (G = 1, -3dB)). It is suitable for twisted pair line drivers, audio applications and general purpose high current amplifiers.
The AD8397 is a dual voltage‑feedback operational amplifier designed for heavy‑load driving with rail‑to‑rail output. It offers a wide supply range (3 V to 24 V), high linear output current (up to 310 mA), low noise (4.5 nV/√Hz at 100 kHz) and low distortion, making it suitable for audio and twisted‑pair line‑driver applications.
The datasheet provides absolute maximum ratings, electrical specifications, typical performance curves, and package information. The device is supplied in a standard 8‑lead SOIC and a thermally enhanced 8‑lead SOIC EPAD package, both rated for operation from –40 °C to +85 °C. Detailed tables list bandwidth, slew rate, input‑output characteristics, and power‑supply requirements for various supply voltages.
