The AD8022 is a dual-channel high performance low noise op amp with ultra-wide supply range, low power consumption and high output swing. It is suitable for ADSL, VDSL, HDSL and proprietary xDSL systems, low noise instrumentation front end, ultrasound preamplifier, active filters and 16-bit ADC buffers.
The AD8022 is a dual, high‑speed, low‑noise voltage‑feedback operational amplifier offered in 8‑lead SOIC and MSOP packages. It delivers a typical small‑signal bandwidth of 130 MHz, a slew rate of 40 V/µs, and a very low voltage noise of 2.5 nV/√Hz at 100 kHz, making it suitable for xDSL receiver front‑ends and low‑noise instrumentation.
The document includes detailed electrical specifications, absolute maximum ratings, ordering information, layout guidelines, and evaluation‑board schematics. It also outlines recommended ESD precautions and provides mechanical dimensions for PCB designers.
