Product details

Precision shunt reference for tight-regulation rails

The LM4050AEM3-2.5+T: With a 15 mA output current capability and a low 65 µA cathode current, this reference suits precision ADC/DAC bias, power-supply monitoring, and portable instrumentation where board space is tight.

Noise and drift matter for signal-chain accuracy

Wideband noise from 10 Hz to 10 kHz is specified at 35 µVrms — low enough that it does not dominate the noise floor of a 16-bit ADC sampling at moderate rates.

SOT-23-3 package and surface-mount assembly

Housed in a standard SOT-23-3 (TO-236-3 / SC-59) package, the device is surface-mount only and fits into compact mixed-signal layouts without needing a dedicated reference footprint. Supplied on Tape & Reel or Cut Tape, it is ready for pick-and-place assembly in volume production or prototype runs.
