TS4061BICT-1.25

Overview

The TS4061BICT-1.25 is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a fixed output of 1.25V with an initial accuracy of ±0.2%. It operates within an industrial temperature range of -40°C to +85°C and features a maximum temperature coefficient of 35ppm/°C. The device draws an ultra-low operating current of 10µA at 25°C and supports up to 15mA output current. Packaged in SOT-323, it exhibits low noise characteristics, including 10µVp-p from 0.1Hz to 10Hz.

Feature Summary

• Provides stable fixed output voltage over the industrial temperature range
• Ultra-low operating current suitable for power-restricted designs
• High precision with ±0.2% initial accuracy
• Very low low-frequency noise performance

Applications

• Portable battery-powered instrumentation
• Data acquisition systems requiring precise references
• Space-constrained surface mount designs

Procurement Notes

Verify component status as obsolete or end-of-life through official manufacturer channels before design finalization. Confirm package integrity and moisture sensitivity level compliance during storage and handling. Ensure replacement strategies are documented if active sourcing is required for production continuity.

Selection Notes

Select this component when space-saving SOT-323 packaging is mandatory alongside high precision requirements. The low quiescent current makes it suitable for battery-operated applications where energy efficiency is critical. Verify that the 15mA load capability meets system demands while maintaining stability with capacitive loads.

Part Context

This part belongs to the TS4061 family of precision voltage references designed for industrial applications. It shares core architectural features with other variants in the series but differs in specific output voltage and tolerance grades. The family emphasizes miniaturization and low power consumption for modern electronic designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the TS4061 series offering different voltage outputs or tolerances. Verify availability of successor components from STMicroelectronics if the current part is discontinued.
