NSREF3133-DSTR

Overview

The NSREF3133-DSTR is a precision voltage reference from the NSREF31xx series by NOVOSENSE, designed for high-accuracy data sampling applications. It delivers a fixed output voltage of 3.3V with an initial accuracy of ±0.2%. The device features ultra-low temperature drift, typically 5ppm/°C and maximally 15ppm/°C, ensuring stability across wide temperature ranges. It exhibits low noise, with a typical peak-to-peak value of 20µV in the 0.1Hz to 10Hz band, and consumes only 130µA of current. The part supports both industrial and automotive grades, with the latter meeting AEC-Q100 Grade 1 standards for operation between -40°C and 125°C.

Procurement Notes

Verify that the specific suffix matches the required operating temperature range and reliability grade. Confirm whether the ordered unit corresponds to the industrial or automotive specification, as performance criteria differ between these variants. Ensure compatibility with system voltage requirements and load conditions before integration.

Selection Notes

Select this component when high precision and low drift are critical for analog-to-digital conversion accuracy. The NSREF31xx series is appropriate for battery-powered applications due to its low quiescent current and lack of output capacitor requirement. Choose the automotive grade if the application demands compliance with AEC-Q100 standards for harsh environments.
