5 MHz gain-bandwidth in a SOT-23-5 footprint
The MAX4322EUK+T: The rail-to-rail output stage allows the output to swing within millivolts of either supply rail, preserving dynamic range in low-voltage systems operating from 2.4 V to 6.5 V.
Parametric fit for signal-chain design
The 5 MHz gain-bandwidth product sets the small-signal closed-loop bandwidth: at a noise gain of 10, the -3 dB point is approximately 500 kHz. For precision DC applications below 1 mV offset, a zero-drift or chopper-stabilized amplifier would be required. The rail-to-rail output eliminates the need for a negative supply in single-supply topologies, simplifying the power tree.
Package and board integration
The SOT-23-5 package occupies approximately 2.9 mm × 1.6 mm on the PCB, with a 0.95 mm pin pitch. The SC-74A / SOT-753 case code is a standard JEDEC outline; land patterns per IPC-7351B are available from the package drawing. Surface-mount assembly with tape-and-reel or cut-tape packaging supports both prototyping and volume production.
Lifecycle and compliance status
It is ROHS3 compliant, meeting the current EU restriction on hazardous substances. For BOM planning, the active status means the part is available through authorized distribution channels. No pin-compatible second-source or successor is listed in the manufacturer's cross-reference data.
