The AD622ANZ is a single-channel instrumentation amplifier from Analog Devices, built for precision sensor signal conditioning in a through-hole 8-DIP package. It delivers a 1 MHz -3dB bandwidth with a 1.2 V/µs slew rate, enough to handle bridge sensors, thermocouples, and strain-gauge outputs without rolling off the signal. The 60 µV input offset and 2 nA input bias current keep the error budget tight for a 5.2 V to 36 V supply range.
The 5.2 V minimum supply means a single 5 V rail won't cut it — plan for at least ±2.6 V dual or a 6 V single supply. The 36 V maximum gives you room for industrial ±15 V rails. Output can source or sink 18 mA per channel, enough to drive a typical ADC input or a 4–20 mA transmitter front end, but not a heavy cable or relay coil.
Package and lifecycle — a through-hole part that's still active
The AD622ANZ is in an 8-DIP (0.300", 7.62 mm) through-hole package, shipped in tubes. For a BOM that needs a socketed instrumentation amp for low-volume or repair runs, this is a straightforward fit without last-time-buy pressure.
