HJ172
It 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. The supply voltage range spans from ±2.25 V to ±16 V, with input levels extending down to the negative rail and output levels reaching the rail‑to‑rail. Its pinout and electrical characteristics are identical to those of the foreign‑made OPA2172/4172, enabling direct substitution in existing designs. It is well suited for military‑grade electronic systems.
