Low-power general-purpose op-amp for battery and industrial rails
With a 430 kHz gain-bandwidth product and a 0.16 V/µs slew rate, this op-amp is deliberately slow — that is the tradeoff for the 50 µA quiescent current.
Supply voltage range: 2.2 V to 36 V — single-supply flexibility
The 2.2 V minimum supply means the OPA244UA operates from a single Li-ion cell down to its end-of-discharge voltage, while the 36 V maximum covers 24 V industrial buses with margin. This wide span eliminates the need for a rail-splitter or a second regulator in mixed-voltage boards. The input common-mode range is not rail-to-rail (the datasheet margin applies), so check the input swing against the supply rails for your specific signal.
The ROHS3 compliance is current.
