The supply span from 2.7 V to 40 V lets it run on a single lithium cell or a 24 V industrial rail without a secondary regulator.
Supply voltage range — 2.7 V to 40 V
The 2.7 V minimum supply means this op-amp stays alive through a lithium cell's full discharge curve.
Quiescent current and output drive
At 130 µA supply current, the OPA990SIDBVR fits power-budgeted channels where every microamp counts — think loop-powered transmitters or multi-channel data-acquisition front ends. The 80 mA output per channel can drive a moderate headphone load or an ADC reference buffer directly, though the 1.1 MHz GBW limits the bandwidth for high-frequency signals.
The SOT-23-6 footprint (supplier device package SOT-23-6) is a standard small-outline transistor package, board-compatible with many single op-amps in the same pinout.
