Supply range and quiescent current — fit for battery-powered designs
The 2.2 V minimum supply span lets this part run directly from two alkaline cells or a Li-ion battery near end-of-discharge, while the 5.5 V maximum covers 5 V regulated rails. Total supply current for both channels is 2.01 mA, which keeps the power budget modest in multi-stage analog front-ends. For battery-powered sensor nodes or portable instruments, the combination of low minimum supply and moderate quiescent current avoids the need for a boost converter, simplifying the power tree.
Each channel can source or sink 52.6 mA, enough to drive a 100 Ω load to within a few hundred millivolts of the rails, or to charge the sampling capacitor of a successive-approximation ADC in one acquisition window. The 260 nA input bias current is typical for a bipolar-input op-amp; it matters when the source impedance exceeds 100 kΩ, where the bias current multiplied by the source resistance starts to contribute a DC error comparable to the 80 µV offset. For high-impedance sensors like pH probes or photodiodes, a CMOS-input alternative would be a better fit.
Package and footprint — 8-VSSOP layout notes
The small body saves board area compared to an SOIC-8, but the fine pitch demands careful solder-paste stencil design to avoid bridging. Decoupling with a 0.1 µF ceramic placed within 2 mm of the supply pin is recommended; the low supply current means a 1 µF bulk cap per rail is sufficient for most layouts.
