SPX2431AM-L

Overview

The SPX2431AM-L is a precision adjustable shunt voltage reference manufactured by MaxLinear. It operates within an output voltage range of 2.5 V to 20 V and features an initial accuracy of 0.5%. The device supports a maximum shunt current of 100 mA with a minimum operating current of 400 uA. It exhibits a temperature coefficient of 30 PPM/C and functions at input voltages up to 2.52 V above the reference. The component is housed in a SOT-23-3 package for surface mount installation and operates between 0 C and +105 C.

Feature Summary

Provides stable, adjustable reference voltage via external resistor divider
Maintains high precision with low temperature drift characteristics
Supports wide operating current range from microamps to 100 mA

Applications

Precision analog-to-digital converter (ADC) reference sources
Digital-to-analog converter (DAC) voltage references
Battery-powered instrumentation circuits requiring stable biasing

Procurement Notes

Verify end-of-life status as the component is listed as discontinued. Confirm availability through authorized distributors or surplus channels. Ensure compatibility with existing PCB footprints and thermal requirements. Check RoHS compliance details before integration. Validate supply chain reliability due to potential obsolescence constraints.

Selection Notes

Select this component when precise, adjustable shunt regulation is required in compact designs. Consider the 0.5% initial accuracy and 30 PPM/C temperature coefficient for stability needs. Evaluate the 100 mA max current capability against load requirements. Verify that the SOT-23-3 package fits the mechanical constraints. Assess if the 2.5 V to 20 V output range meets system specifications.

Part Context

The SPX2431 series belongs to MaxLinear's portfolio of power management integrated circuits, specifically under voltage references. This family offers adjustable shunt regulators designed for applications demanding high precision and stability.
