That combination puts it in the sweet spot for multi-channel signal chains where board space and power budget are tight — think portable instrumentation, multi-channel ADC drivers, or active filters in battery-operated equipment. ## Input bias and offset — what the 0.2 pA and 500 µV mean for sensor front-ends With 0.2 pA input bias current, the OPA2338UA is well suited for high-impedance sources like photodiodes, pH probes, or piezoelectric sensors where bias current would otherwise create a significant DC error across the source resistance. The 500 µV input offset voltage is typical for a CMOS amplifier at this speed — adequate for 8- to 10-bit precision, but for 12-bit+ systems you'll want to budget for offset calibration or select a lower-Vos variant.","metaTitle":"OPA2338UA CMOS Op-Amp, 12.5 MHz, Rail-to-Rail Output, 8-SOIC","metaDescription":"OPA2338UA dual CMOS op-amp from TI's MicroAmplifier™ series. 12.5 MHz GBW, 4.6 V/µs slew rate, rail-to-rail output, 525 µA supply per channel.
