Product details

The Texas Instruments LM4040A41IDBZRG4 is a precision shunt voltage reference delivering a fixed 4.096 V output with a tight ±0.1% initial tolerance and a temperature coefficient of 100 ppm/°C.

Shunt topology — no load-current minimum to manage

As a shunt reference, the LM4040A41IDBZRG4 sinks current through its cathode to regulate the output voltage. The 80 µVrms noise spec (10 Hz to 10 kHz) is clean enough for a 12-bit ADC reference without additional filtering in most layouts.

The SOT-23-3 footprint is shared across the LM4040 family, so a pin-compatible alternate within the same series is straightforward if a different voltage or tolerance tier is needed.

Frequently asked questions

What package does the LM4040A41IDBZRG4 come in?

It is supplied in a SOT-23-3 surface-mount package (also listed as TO-236-3 / SC-59). The shipping format is Tape & Reel (TR). The three-pin configuration is standard for shunt references: cathode, anode, and no-connect.
