NSREF3130-DSTR

Overview

The NSREF3130-DSTR is a fixed-output voltage reference IC from the NOVOSENSE NSREF31xx series, providing a nominal output of 3.0 V. It operates within an input voltage range of 1.8 V to 5.5 V and features a maximum temperature coefficient of 15 ppm/°C with a typical value of 5 ppm/°C. The device exhibits low noise, with a peak-to-peak value of 20 µV in the 0.1 Hz to 10 Hz bandwidth at 2.5 V output conditions. It consumes a typical quiescent current of 130 µA and offers high initial accuracy of ±0.2%. The component is housed in a SOT-23-3L package.

Feature Summary

• Delivers high precision with ±0.2% initial accuracy and ultra-low temperature drift for stable ADC sampling across wide temperature ranges.
• Features advanced low-noise design minimizing 0.1Hz-10Hz interference, ensuring signal integrity in sensitive data acquisition systems.
• Operates with minimal power consumption and requires no output capacitor, simplifying circuit layout and enhancing reliability in battery-powered applications.

Applications

• High-precision analog-to-digital converter (ADC) reference sources in industrial automation
• Portable measurement devices and field transmitters requiring low power operation
• Automotive electronics meeting AEC-Q100 Grade 1 reliability standards

Procurement Notes

Verify the specific suffix 'DSTR' against the manufacturer's official datasheet to confirm packaging type, typically tape and reel. Ensure the order matches the required automotive or industrial grade variant, as the NSREF31xx series includes both. Confirm RoHS compliance status and check for any recent supply constraints or alternative lot codes that may affect lead times or compatibility.

Selection Notes

Select this component when system requirements demand superior thermal stability compared to the NSREF30xx series, specifically where the 15 ppm/°C maximum drift is critical. It is suitable for designs needing a 3.0 V reference with minimal quiescent current draw. Consider the SOT-23-3L footprint for space-constrained PCB layouts. Validate that the 1.8 V minimum input voltage aligns with the system's lowest operating supply condition.

Part Context

The NSREF3130-DSTR belongs to the NSREF31xx sub-series of NOVOSENSE voltage references, designed for high-performance applications. This series complements the NSREF30xx line by offering tighter temperature coefficients, targeting demanding environments in automotive and industrial sectors. The product line emphasizes robustness, low noise, and energy efficiency to support modern sensor interfaces and power management architectures.

Replacement Considerations

Direct substitutes within the same family include other NSREF31xx variants with different fixed output voltages, such as NSREF3125 or NSREF3150, provided the voltage requirement differs. Cross-brand replacements require matching the 3.0 V output, SOT-23-3L package, and ≤15 ppm/°C temperature coefficient specifications.
