The OP297 dual op‑amp delivers ultra‑low offset voltage, minimal bias current, and high open‑loop gain in an 8‑lead SOIC, CERDIP or PDIP package. Its performance makes it suitable for strain‑gauge, thermocouple, instrumentation, photodiode, and high‑gain linear applications, especially where battery power and low supply voltage are required.
Key specifications include a typical input offset of 50 µV, input bias current of 100 pA, common‑mode rejection of 120 dB, and a supply range from ±2 V to ±20 V. The device is offered in CERDIP (OP297EZ), PDIP (OP297FP/GP), and SOIC (OP297FS/GS) packages, and includes ESD protection and guidelines for guarding and shielding to preserve its high input impedance.

The device can be operated with a supply voltage up to ±20 V.
The OP297 is offered in 8‑lead CERDIP (OP297EZ), PDIP (OP297FP, OP297GP) and SOIC (OP297FS, OP297GS) packages.
Because the OP297 is ESD‑sensitive, proper ESD precautions should be taken to avoid damage.
