Dual High Speed, Low Noise Op Amp AD8022 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 2.5 nV/√Hz voltage noise @ 100 kHz 1.2 pA/√Hz current noise MTPR < 66 dBc (G = +7) SFDR 110 dB @ 200 kHz High speed 130 MHz bandwidth (3 dB), G = +1 Settling time to 0.1%, 68 ns 50 V/μs slew rate High output swing: ±10.1 V on ±12 V supply Low offset voltage, 1.5 mV typical FUNCTIONAL BLOCK DIAGRAM OUT1 1 –IN1 2 +IN1 3 –VS 4 AD8022 – + – + 8 +VS 7 OUT2 6 –IN2 5 +IN2 01053-001 Figure 1. APPLICATIONS Receiver for ADSL, VDSL, HDSL, and proprietary xDSL systems Low noise instrumentation front end Ultrasound preamps Active filters 16-bit ADC buffers 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.
