Overview
The AD8017AR-REEL7, produced by Analog Devices Inc., is a low-cost, dual high-speed operational amplifier designed for applications requiring high output current and low distortion. This amplifier is optimized for use in single-supply xDSL systems, such as ADSL, SDSL, and VDSL, where low distortion and high output drive capabilities are essential. The AD8017 is fabricated in Analog Devices' high-speed XFCB process, ensuring minimal distortion and power dissipation. It operates over a commercial temperature range of –40°C to +85°C and is packaged in a thermally enhanced 8-lead SOIC package, which helps in efficient heat dissipation without the need for an external heat sink.
