Product details

10V shunt reference in a SOT-23-3 footprint

It comes in a SOT-23-3 package, making it a drop-in fit for board-level biasing and ADC reference applications where board space is constrained.

Temperature drift and noise floor

The temperature coefficient is rated at 100 ppm/°C, so the output shifts by roughly 1 mV per 10°C change.

Shunt operation and cathode current

As a shunt reference, it regulates by sinking current through the cathode. The minimum cathode current is 125 µA, and the maximum continuous output current is 15 mA.

Frequently asked questions

What is the temperature coefficient of LM4040A10IDBZRG4?

The temperature coefficient is 100 ppm/°C.

Is LM4040A10IDBZRG4 a good choice for a 10V reference?

Yes, for applications requiring a fixed 10V reference with ±0.1% accuracy and low drift in a small SOT-23-3 package. The shunt topology is simple and requires only one external resistor. The 125 µA minimum cathode current and 15 mA output current cover most precision analog and ADC reference loads.
