Product details

4.096V shunt reference — what it delivers

The Texas Instruments LM4040B41IDBZTG4 is a precision shunt voltage reference with a fixed 4.096V output, ±0.2% initial tolerance, and 80 µVrms noise over 10 Hz to 10 kHz. It operates as a two-terminal shunt device, drawing a cathode current of 88 µA typical while supplying up to 15 mA to the load.

Tolerance and temperature drift — the so-what

For a 12-bit ADC with a 4.096V reference, that drift contributes about 1 LSB of error over the full temperature span — acceptable for most industrial control loops but worth derating for a 16-bit converter.

Frequently asked questions

Is LM4040B41IDBZTG4 RoHS compliant?
