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 10 when driving capacitive loads. Manufactured on ADIs 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 e (nV/ Hz) N voltage recovery and wide bandwidth make the AD8022 ideal as the receive channel front end to an ADSL, VDSL, or proprietary i (pA/ Hz) N xDSL transceiver design. 1 10 100 1k 10k 100k 1M 10M In an xDSL line interface circuit, the AD8022s op amps can be FREQUENCY (Hz) configured as the differential receiver from the line transformer Figure 2.
