SPX1431S-L/TR

Overview

The SPX1431S-L/TR 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 0.4%. The device supports a maximum shunt current of 100 mA and maintains a temperature coefficient of 30 ppm/°C. It is housed in an 8-SOIC surface-mount package and functions across a commercial temperature range from 0°C to +105°C.

Feature Summary

Provides precise adjustable shunt regulation with high initial accuracy
Operates over a wide output voltage range up to 20 V
Designed for surface-mount integration in compact circuits

Applications

Precision analog-to-digital converter (ADC) reference sources
Digital-to-analog converter (DAC) voltage references
Battery-powered instrumentation calibration

Procurement Notes

This component is officially obsolete and no longer manufactured by MaxLinear. Verification of availability is restricted to existing stock or third-party distributors. Engineers must confirm the authenticity of available units and assess long-term supply chain risks before finalizing designs that rely on this specific part number.

Selection Notes

Designers requiring this functionality should evaluate alternative components due to the obsolete status of the SPX1431S-L/TR. Selection criteria should focus on matching the required output voltage range, accuracy specifications, and thermal performance while ensuring the substitute part is actively supported by the manufacturer for new production volumes.

Part Context

The SPX1431S-L/TR belongs to the SPX1431 series of shunt adjustable precision references. This family is categorized under Power Management ICs (PMIC) specifically as Voltage References. The device utilizes an 8-SOIC package, distinguishing it from other series members that may use SOT-23 or TO-263 packages.

Replacement Considerations

Publicly confirmed substitutes include TL1431ACDT from STMicroelectronics. Designers should verify pin compatibility and electrical parameter alignment when transitioning to alternative parts.
