REF4132B33DBVRQ1 Description

Short technical summary and product information.

The REF4132B33DBVRQ1 from Texas Instruments is a high-precision, low-noise, and low-power series voltage reference suitable for automotive applications. It is AEC-Q100 qualified and operates within a temperature range of -40°C to +125°C.

 

This voltage reference IC is available in multiple output voltage options, including 2.5V, 3V, 3.3V, 4.096V, and 5V, with a maximum initial accuracy of ±0.05%. It features a temperature coefficient as low as 12 ppm/°C (A grade) and 30 ppm/°C (B grade), ensuring stable performance across varying temperatures. The device supports an output current of ±10 mA and has a low quiescent current of typically 0.075 mA, with a maximum of 100 µA.

 

Designed for compact applications, the REF4132B33DBVRQ1 comes in a small 5-pin SOT-23 package with surface mount termination. It includes an enable pin for power management and exhibits low output noise of 37.5 µVPP (typ) from 0.1 Hz to 10 Hz. Its excellent long-term stability of 30 ppm/1000 hrs makes it a reliable choice for demanding automotive systems.
