GENERAL DESCRIPTIONS
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/√Hz 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.
