Product details

3 V reference with ±0.1% tolerance — what it means for the ADC front-end

The Texas Instruments LM4128AMF-3.0/NOPB is a precision series voltage reference delivering a fixed 3 V output with ±0.1% initial accuracy. Housed in a SOT-23-5 package, it draws 100 µA quiescent supply current and can source up to 20 mA to the load. The 75 ppm/°C temperature coefficient keeps the output stable across the full -40°C to 125°C junction temperature range, making it suitable for industrial sensor interfaces, automotive ECU references, and precision ADC/DAC bias circuits where board space is tight.

Active, ROHS3, and available in tape and reel

The LM4128AMF-3.0/NOPB carries an active lifecycle status and is ROHS3 compliant. The NOPB suffix confirms lead-free (RoHS) construction. Packaging options include Tape & Reel (TR) and Cut Tape (CT), which covers both volume production reels and prototype or small-batch quantities.

Frequently asked questions

Does LM4128AMF-3.0/NOPB come in tape and reel packaging?

Yes, it is available in Tape & Reel (TR) and Cut Tape (CT) options, as well as standard tube packaging for smaller quantities.

What is a drop-in equivalent or alternative for LM4128AMF-3.0/NOPB?

A close functional alternative is the LM4132AMF-4.1/NOPB, which offers a tighter ±0.05% tolerance and a lower 20 ppm/°C drift, but outputs 4.096 V instead of 3 V. Verify pin compatibility and output voltage before substituting.
