It delivers a 1.9 MHz gain-bandwidth product and a 3 V/µs slew rate, with rail-to-rail output swing that maximizes dynamic range in single-supply or split-rail designs. The supply span runs from 5 V to 30 V, covering 5 V logic rails, 12 V industrial buses, and ±15 V analog supplies.
Supply voltage range and rail-to-rail output
The AD822ARMZ operates from a minimum supply of 5 V up to a maximum of 30 V. That range covers common single-supply rails (5 V, 12 V, 24 V) and split supplies like ±5 V or ±15 V. The rail-to-rail output stage swings within millivolts of each rail, so a 5 V single-supply design gets nearly the full 0 V to 5 V output range — useful when driving an ADC input or a control line without a negative rail.
Bandwidth, slew rate, and input characteristics
With a 1.9 MHz gain-bandwidth product and a 3 V/µs slew rate, this op-amp handles audio-frequency signals, sensor outputs up to a few hundred kHz, and control-loop compensation without slew-rate limiting. The input bias current is 2 pA (typical), which suits high-impedance sources like photodiodes or pH probes where bias current error matters. Input offset voltage is 400 µV maximum — adequate for general-purpose signal conditioning but not precision instrumentation.
Package and mounting
The supplier device package is 8-MSOP. It ships in Tube form. The small footprint saves board area compared to an SOIC-8, but the fine pitch (0.65 mm typical for MSOP) calls for careful solder-paste stencil design and inspection.
