HJ2172
The HJ2172 is a high‑voltage, high‑precision, low‑drift CMOS operational amplifier, featuring low offset voltage, high slew rate, high gain‑bandwidth product, and strong output current drive capability. It operates from a supply range of ±2.25 V to ±16 V, with input levels extending down to the negative rail and rail‑to‑rail output. The device’s pinout and electrical characteristics are identical to those of the foreign‑made OPA2172/4172, allowing for drop‑in replacement. It is well suited for military‑grade electronic systems.
