PRODUCT DESCRIPTION
The AD8022 consists of two low noise, high speed, voltage
feedback amplifiers. Both inputs add only 2.5nV
√
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 +5V to ±12V
supplies, the AD8022 consumes only 3.5m7A/Amp quiescent
current. The AD8022 is available in both an 8 pin MicroSOIC
and 8 pin SOIC packages. Fast overvoltage recovery, 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
differential receiver from the line transformer or as
independent active filters in an xDSL line interface circuit. The
AD8022 is stable at gain of 2.
AD8022 can be configured as a differential
receiver with active filter, as shown in this xDSL
line interface application.
