Product details

10V shunt reference with ±0.2% initial accuracy

The LM4040B10IDBZTG4 is a fixed 10V shunt voltage reference from Texas Instruments, offering a tight ±0.2% initial tolerance and a temperature coefficient of 100ppm/°C.

Output current and noise — what limits the load

The shunt reference can sink up to 15 mA of output current, with a minimum cathode current of 125 µA required for regulation. The output noise is specified at 180 µVrms over a 10 Hz to 10 kHz bandwidth — adequate for 12-bit systems but worth budgeting for in 16-bit+ designs where the noise floor matters.

Frequently asked questions

Is LM4040B10IDBZTG4 obsolete or end-of-life?

No. There is no record of obsolescence or end-of-life notification from Texas Instruments.

Can LM4040B10IDBZTG4 be used with a 5V supply?

No. This is a shunt reference with a fixed 10V output. A 5V supply is below the minimum operating voltage required to bias the reference into regulation. For a 5V rail, consider a lower-voltage variant in the LM4040 family (e.g., 2.5V or 4.096V outputs).
