5 µV offset, 0.2 pA bias — precision for high-impedance sources
That combination lets the OPA2376AID interface directly with photodiodes, pH probes, or strain-gauge bridges without a separate buffer stage — the bias current won't load the source, and the offset won't create a DC error that needs software calibration. The 50 mA output drive per channel is enough to swing an ADC input or drive a cable capacitance without an external buffer.
Supply range and quiescent current — power budget fit
Supply span runs from 2.2 V to 5.5 V, so it works on a single lithium cell or a regulated 3.3 V / 5 V rail. Total quiescent current is 760 µA for both amplifiers — 380 µA per channel. That keeps the thermal rise low in the 8-SOIC package and makes the part viable for multi-channel data-acquisition boards where the power budget is tight.
