Overview
The LM4132BMF-2.5/NOPB is a precision voltage reference from Texas Instruments, designed to offer high accuracy and stability in a compact SOT-23 (DBV) package. This device leverages CMOS technology to achieve performance comparable to the best laser-trimmed bipolar references but at a lower cost. The use of EEPROM registers for correcting curvature, temperature coefficient, and accuracy on a CMOS band-gap architecture allows for package-level programming, overcoming the limitations of laser-trimmed references during assembly. This makes the LM4132 ideal for applications requiring precise voltage referencing in space-critical and power-sensitive designs.
