AD8022 is a low power dual high speed low noise operational amplifier, ideal for xDSL modem receiver.
The AD8022 consists of two low‑noise, high‑speed voltage‑feedback amplifiers. Each amplifier draws only 4 mA quiescent current and offers a small‑signal bandwidth of 130 MHz, making it suitable for xDSL receivers, ultrasound pre‑amps, and high‑speed ADC buffers. It is available in 8‑lead SOIC and MSOP packages and operates from a wide supply range of +4.5 V to +13 V.
Typical performance includes a 50 V/µs slew rate, 2.5 nV/√Hz voltage noise at 100 kHz, and an output swing of up to +10.1 V on a +12 V supply. The datasheet also provides layout guidelines, absolute maximum ratings, and ordering information for various package options.
| Voltage Noise (100 kHz) | 2.5 nV/√Hz |
|---|---|
