Product details

8.192 V shunt reference — ±0.5% tolerance, TO-92-3

This voltage is a common reference for ADC and DAC circuits, particularly in 12- and 16-bit data-acquisition systems where a stable mid-rail or full-scale reference is needed.

Texas Instruments has ended production; no last-time-buy window remains open. New designs should not target this order code. No official successor is listed on the manufacturer's record.

Shunt architecture and output current limits

As a shunt reference, the LM4040CIZ-8.2/NOPB sinks current through the cathode to regulate the output voltage.

Through-hole TO-92-3 — board-fit considerations

The three leads are typically cathode, anode, and no-connect (NC) — the pinout is standard for this family but should be verified against the datasheet for the specific orientation. For high-volume through-hole assembly, plan for tube-fed or vibratory-bowl feeding.

Frequently asked questions

Is LM4040CIZ-8.2/NOPB obsolete?

Yes, the manufacturer has marked this part as Obsolete. No last-time-buy window remains. For new designs, select an active alternative from the LM4040 family.

What is the accuracy of LM4040CIZ-8.2/NOPB?

The initial tolerance is ±0.5%, and the temperature coefficient is 100 ppm/°C.
