Product details

Dual CMOS op-amp for low-power signal chains

Each channel draws 750 µA quiescent current while delivering a 5.5 MHz gain-bandwidth product and a 6 V/µs slew rate — enough bandwidth for audio-band filtering, sensor conditioning, and 10- to 100-kHz ADC drivers without burning through the battery budget. Input bias current is 0.2 pA typical, so high-impedance sources like photodiodes or pH probes see negligible offset error from the amplifier itself.

Output drive and input offset — bench-level limits

The 150 µV input offset voltage (typical) is acceptable for 12-bit systems with gains below 100; for higher precision, a chopper-stabilized amplifier would be the better call.
