Quad op-amp for power-conscious industrial and battery circuits
Each of the four amplifiers draws 85 µA typical supply current, making this a fit for battery-powered instrumentation, sensor signal conditioning, and low-frequency filtering in industrial control loops. The gain-bandwidth product is 100 kHz with a slew rate of 0.05 V/µs — enough for DC and low-frequency AC signals, but not for audio or fast pulse work. Supply range spans 3 V to 26 V, so it runs off a single lithium cell or a 24 V industrial rail without a separate regulator.
What the 85 µA supply current buys you
At 85 µA per amplifier, the whole quad draws roughly 340 µA quiescent. That is the main reason to pick this part over a faster quad like the OPA4374AIPWT (600 µA per channel) — you trade bandwidth for battery life. The 2 mV input offset voltage and 2 nA input bias current are adequate for thermocouple or bridge amplifier circuits where the signal is in the millivolt range and the source impedance is moderate.
Package and rework considerations
The narrow SOIC pitch (1.27 mm) is forgiving for hand rework; lift the part, not the pad. No exposed thermal pad, so the dissipation path is through the leads — keep the ambient below 85°C for continuous operation near the 10 mA output limit.
Lifecycle and sourcing
The NOPB suffix indicates lead-free (no Pb) finish, compatible with RoHS assembly lines.
