TL4275KTTR

Overview

The TL4275KTTR is a fixed series voltage reference integrated circuit manufactured by Texas Instruments. It provides a stable 3.3 V output with an initial accuracy of ±0.15%. The device operates within an input voltage range of 2.7 V to 60 V and draws a typical quiescent current of 5 mA. It is housed in a compact SC-70 surface-mount package, suitable for space-constrained designs requiring high precision.

Feature Summary

• Provides a fixed 3.3 V output with high initial accuracy of ±0.15%.

Applications

• Precision analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• Measurement instrumentation circuits

Procurement Notes

Verify the specific suffix 'KTTR' corresponds to the SC-70 package and tape-and-reel configuration. Confirm the 3.3 V nominal output and ±0.15% accuracy class match the design requirements. Ensure compatibility with the intended operating temperature range and input voltage constraints before finalizing procurement.

Selection Notes

Select this component when a low-noise, high-accuracy fixed reference is required for single-supply applications. The SC-70 package offers a small footprint for dense PCB layouts. Consider the 5 mA quiescent current draw against system power budgets. Verify that the 60 V maximum input voltage exceeds the highest expected supply rail.

Part Context

This part belongs to the TL4275 family of precision voltage references from Texas Instruments. These devices are designed for applications demanding stable reference voltages with minimal drift over temperature and time. The family includes various output voltages and packages to support diverse industrial and consumer electronics needs.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar accuracy and package types. Verify that any substitute maintains the required 3.3 V output and ±0.15% tolerance without altering the circuit's thermal or electrical characteristics.
