REF6133IDGKT

Overview

The REF6133IDGKT is a high-precision series voltage reference manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It provides a fixed output voltage of 3.3 V with an initial accuracy of 0.05% and a temperature coefficient of 8 ppm/°C. The device operates within an input voltage range up to 5.5 V and supports a maximum shunt current of 4 mA. It functions reliably across a temperature range of -40°C to +125°C, consuming typical supply current of 820 µA.

Feature Summary

• Integrated high-bandwidth buffer for low output impedance
• High precision with 0.05% initial accuracy
• Low temperature drift of 8 ppm/°C
• Shutdown capability for power reduction

Applications

• Precision data acquisition systems
• Industrial process control instrumentation
• Medical equipment requiring stable references
• High-resolution analog-to-digital converter front ends

Procurement Notes

Verify the specific suffix (KT) indicates cut-tape packaging rather than reel quantities when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure moisture sensitivity level requirements are met during storage and handling procedures to maintain component integrity.

Selection Notes

Select this component when a stable 3.3 V reference is required with tight tolerance specifications. The integrated buffer simplifies circuit design by eliminating external compensation components. Consider the 8 ppm/°C drift rate against environmental temperature variations to ensure long-term stability meets system accuracy goals.

Part Context

This part belongs to the REF61xx family of high-precision voltage references from Texas Instruments. These devices are designed for applications demanding superior performance over standard bandgap references. The VSSOP-8 package allows for compact PCB layouts while maintaining thermal performance suitable for industrial environments.

Replacement Considerations

Direct substitutes include other members of the REF61xx series such as REF6130 or REF6150, depending on required output voltage. Verify pin compatibility and electrical parameters before substitution.
