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. Low-noise receive amplifiers in the AD8022 are independent voltage feedback amplifiers and can be configured as the differ- ential receiver from the line transformer or as independent active filters in an xDSL line interface circuit.
