AD8022ARM Datasheet

Special Purpose Amplifiers


The AD8022ARM 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 AD8022ARM 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 AD8022ARM ideal as the receive channel front end to an ADSL, VDSL, or proprietary xDSL transceiver design. In an xDSL line interface circuit, the AD8022ARM’s op amps can be configured as the differential receiver from the line transformer or as independent active filters. AD8022ARM Features •Low power amplifiers provide low noise and low distortion, ideal for xDSL modem receiver •Wide supply range: +5 V, ±2.5 V to ±12 V voltage supply •Low power consumption: 4.0 mA/Amp •Voltage feedback •Ease of Use •Lower total noise (insignificant input current noise contribution compared to current feedback amps) •Low noise and distortion •High speed •High output swing: ±10.1 V on ±12 V supply •Low offset voltage, 1.5 mV typical AD8022ARM Applications •Receiver for ADSL, VDSL, HDSL, and proprietary•xDSL systems •Low noise instrumentation front end •Ultrasound preamps •Active filters •16-bit ADC buffers
