Low-power general-purpose op amp in a hand-solderable SOT-23-5
It draws only 25 µA of supply current per amplifier, making it a strong candidate for battery-operated or always-sensing circuits where every microamp counts. The 200 kHz gain-bandwidth product and 0.115 V/µs slew rate are modest but adequate for filtering, signal conditioning, and sensor buffering in the DC to low-audio range. The SOT-23-5 package is easy to hand-solder with a fine-tip iron and fits on compact boards.
The 25 µA supply current is the headline number for power-sensitive designs. At this quiescent level, the op amp can be left powered continuously in a sensor node or a wearable without dominating the battery budget. The 200 kHz GBW sets the usable bandwidth for closed-loop gain — expect a gain of 10 to be flat to about 20 kHz, which covers most audio and sensor filtering needs. Input offset voltage is 500 µV typical, which is fine for general-purpose signal chains but worth noting if you are amplifying sub-millivolt signals. The 1 pA input bias current suits high-impedance sources like pH probes or photodiode amplifiers.
Temperature range and environment
The industrial temperature grade means it will hold its offset and bias specs across the range, not just at room temperature.
