Micropower quad op-amp for battery and low-frequency signal chains
Each of the four amplifiers draws just 57 µA total supply current, making this part a fit for battery-powered instrumentation, portable medical devices, and remote sensor interfaces where every microamp counts. The gain-bandwidth product of 110 kHz and slew rate of 0.05 V/µs confirm this is a low-frequency part — think DC signal conditioning, temperature monitoring, or photodiode amplification, not audio or motor-control loops. The 0.7 pA input bias current suits high-impedance sources such as pH probes or pyroelectric sensors without loading the signal. Supply voltage spans from 3 V up to 16 V, accommodating both single lithium-ion battery rails and traditional ±5 V or ±15 V split supplies.
The 14-SO footprint is common across many quad op-amp families, so a board designed for a general-purpose quad op-amp can often accept this part with no layout change — useful when a design needs to cut power without a PCB respin.
