With a gain-bandwidth product of 2.5 MHz and a 7.5 V/µs slew rate, it handles audio-band signals and low-speed multiplexed ADC drivers cleanly.","metaTitle":"TI OPA4191IRUMR CMOS Quad Op-Amp, 2.5 MHz, 5 µV Offset","metaDescription":"TI OPA4191IRUMR quad CMOS op-amp: 2.5 MHz GBW, 5 µV offset, rail-to-rail output, 140 µA/ch, -40 to 125°C.
