Product details

Fixed 8.192 V shunt reference with ±0.1% tolerance

The LM4040AIM3X-8.2/NOPB is a precision shunt voltage reference from Texas Instruments that delivers a fixed 8.192 V output with an initial tolerance of ±0.1% and a temperature coefficient of 100 ppm/°C. It operates as a two-terminal shunt device, requiring only a series resistor from the supply to set the bias current — the cathode current floor is 95 µA, and it can sink up to 15 mA of output current.

The SOT-23-3 package (also known as TO-236-3 or SC-59) is a standard surface-mount footprint that mates with common PCB land patterns.

Frequently asked questions

Is LM4040AIM3X-8.2/NOPB obsolete?

Yes, the LM4040AIM3X-8.2/NOPB is listed as Obsolete. Texas Instruments has discontinued production, and no official replacement part number is provided.

What is the tolerance of LM4040AIM3X-8.2/NOPB?

The initial output voltage tolerance is ±0.1%, which is tight for a shunt reference and suitable for precision analog circuits such as ADC references or comparator thresholds.
