Quad micropower op-amp for industrial and battery-powered signal chains
At 200 kHz gain-bandwidth, this op-amp is intended for low-frequency filtering, buffering, and precision DC amplification — not for video or high-speed data acquisition. The 1 pA typical input bias current suits high-impedance sources such as photodiode transimpedance stages or pH probe buffers, where a bipolar-input part would add unacceptable offset drift. The 200 µV input offset voltage is adequate for 12-bit systems with gain up to 100; for higher resolution, a zero-drift amplifier would be needed. The 140 µA total supply current includes all four amplifiers — about 35 µA per channel — which keeps self-heating negligible in the 14-SOIC package even at elevated ambient temperatures.
Lifecycle and sourcing — active with no near-term EOL signal
Buyers should verify date-code consistency and marking font against TI's factory etch standards when accepting broker stock — the laser etch on the 14-SOIC body should match TI's known plant-specific character set for the week code.
Package and footprint — 14-SOIC with standard pitch
The surface-mount package is compatible with reflow soldering;.
