Single-supply general-purpose op-amp in a compact 8-TDFN
The Maxim Integrated MAX4473ETA-T is a single-circuit general-purpose operational amplifier with a rail-to-rail output stage, housed in an 8-WDFN exposed-pad package (3x3 mm footprint). It delivers a 1.8V/µs slew rate from a supply span of 2.7V to 6.5V, drawing 1.2mA quiescent supply current. The input offset voltage is specified at 500 µV, with an input bias current of 400 nA. Each output channel can source or sink 20 mA.
The 1.8V/µs slew rate supports signals up to roughly 100 kHz at full output swing; for higher-frequency or large-signal applications, budget the settling time against your sampling window.
Supply flexibility and thermal footprint
The 2.7V to 6.5V supply span covers a single lithium-ion cell through a regulated 5V rail, so the same BOM line can serve battery-powered and line-powered designs.
Lifecycle and compliance flag
The critical compliance note: this part is RoHS non-compliant. For builds destined for EU markets or any RoHS/REACH-regulated supply chain, a lead-free alternative must be qualified. The active status gives procurement teams a stable sourcing window, but the RoHS restriction narrows the eligible BOM lines — plan for a restricted-materials exemption or a drop-in replacement.
