The AD8021ARMZ is a low‑noise, high‑speed voltage‑feedback operational amplifier designed for high‑performance signal conditioning applications requiring wide bandwidth, low distortion, and fast settling time.

Key Features

• High speed & low noise:

• Bandwidth: 200 MHz (G = +2)

• Slew rate: 120 V/µs

• Input voltage noise: 2.1 nV/√Hz

• Low distortion & fast settling:

• Excellent spurious‑free dynamic range (SFDR), ideal for driving high‑precision ADCs

• 0.01% settling time: 35 ns (2 V step)

• Flexible power supply:

• Supply voltage range: ±2.5 V to ±6 V (or +5 V to +12 V single supply)

• Low quiescent current: 4.5 mA typical
