The AD8392A is a low power, high output current, quad op amp designed for use as an ADSL/ADSL2+ line driver. It features four current feedback, high current amplifiers, low power operation, multiple power supply modes, high output voltage and current drive, low distortion, and high speed capabilities.
The AD8392A quad operational amplifier provides up to 500 mA peak output current with low quiescent power, making it suitable for ADSL/ADSL2+ central‑office (CO) line drivers. It operates from dual supplies of ±5 V to ±12 V (or single 10 V‑24 V) and offers a differential output swing of over 40 Vpp.
Key features include four current‑feedback amplifiers, programmable bias modes, on‑chip common‑mode generation, and robust thermal packaging. The device is offered in a 28‑lead TSSOP/EP package (AD8392AARE) and a 32‑lead LFCSP package (AD8392AACP).
