Each channel draws 650 nA typical, yet delivers a gain-bandwidth product of 9 kHz and an 11 mA output drive per channel. It is suited for DC or quasi-DC signals: thermocouple conditioning, strain-gauge bridges, photodiode current sensing, and battery voltage monitoring. It cannot track audio or control-loop bandwidths — the TSV912IDT (8 MHz, 4.5 V/µs) is the correct choice for those.","metaTitle":"OA2NP34S CMOS Op-Amp, 9 kHz GBW, 650 nA, Rail-to-Rail","metaDescription":"STMicroelectronics OA2NP34S dual CMOS op-amp: 9 kHz GBW, 650 nA supply per channel, rail-to-rail output, 1.5 V to 5.5 V supply.

The OA2NP34S has a slightly lower GBW (9 kHz vs 10 kHz) and a lower slew rate (0.003 V/µs vs 0.0045 V/µs), but for ultra-low-frequency sensor conditioning the difference is negligible.
