TS4061AICT-1.225

Overview

The TS4061AICT-1.225 is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a fixed output of 1.225V with an initial accuracy of ±0.1%. 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 a typical operating current of 10µA at 25°C and supports up to 15mA output current. Low-frequency noise is specified at 10µVp-p (0.1Hz to 10Hz) and 95µVrms (10Hz to 10Hz). It is housed in a SOT-323 surface-mount package.

Feature Summary

• Provides high precision with ±0.1% initial accuracy at 25°C
• Features ultra-low operating current for power-restricted designs
• Maintains stability when used with capacitive loads

Applications

• Portable battery-powered instrumentation
• Handheld meters
• Data acquisition systems

Procurement Notes

Verify component status as the TS4061AICT-1.225 is listed as obsolete with no remaining stock available from distributors. Confirm alternative sourcing strategies or substitute part numbers before finalizing design specifications. Ensure compliance with RoHS3 standards and check for any specific handling requirements related to the SOT-323 package during assembly.

Selection Notes

Select this component for applications requiring high accuracy and minimal power consumption in compact form factors. The SOT-323 package suits space-constrained designs. Consider the ±0.1% tolerance and low temperature coefficient for precision measurement circuits. Evaluate the 15mA output capability against load requirements to ensure adequate drive strength for downstream components.

Part Context
