PRODUCT DESCRIPTION
The AD8022 consists of two low-noise, high-speed, voltage feedback amplifiers. Both inputs add only 2.5 nV/√Hz of voltage noise. These dual amplifiers provide wideband, low-distortion performance, with high-output current optimized for stability when driving capacitive loads. Operating from +5 V to ±12 V supplies, the AD8022 typically consumes only 4.0 mA/Amp quiescent current. The AD8022 is available in both an 8-lead microSOIC and an 8-lead SOIC package. Fast overvoltage recovery and wide bandwidth make the AD8022 ideal as the receive channel front end to an ADSL, VDSL or proprietary xDSL transceiver design.
