AD8022ARZ Operational amplifier, 2-fold, 50 V/µs, 130 MHz, SO-8

Dual High Speed, Low Noise Op Amp

Description: The AD8022 consists of two low noise, high speed, voltage feedback amplifiers. Each amplifier consumes only 4.0 mA of quiescent current, yet has only 2.5 nV/vHz of voltage noise. These dual amplifiers provide wideband, low distortion performance, with high output current optimized for stability when driving capacitive loads. Manufactured on ADI’s high voltage generation of XFCB bipolar process, the AD8022 operates on a wide range of supply voltages. The AD8022 is available in both an 8-lead MSOP and an 8-lead SOIC. Fast over voltage recovery and wide bandwidth make the AD8022 ideal as the receive channel front end to an ADSL, VDSL, or proprietary xDSL transceiver design. In an xDSL line interface circuit, the AD8022’s op amps can be configured as the differential receiver from the line transformer or as independent active filters.
