REF6041IDGKT

Overview

The REF6041IDGKT is a precision series voltage reference manufactured by Texas Instruments, delivering a fixed output of 4 V. It features an initial accuracy of ±0.05% and a temperature coefficient of 5 ppm/°C. The device operates within an input voltage range up to 5.5 V and supports a maximum shunt current of 4 mA. Designed for surface-mount applications, it utilizes an 8-pin VSSOP package. The component functions across an extended industrial temperature range from -40°C to +125°C, ensuring stable performance in demanding environments.

Feature Summary

• Provides high-precision voltage regulation with low temperature drift characteristics
• Integrates shutdown functionality to minimize power consumption during idle states
• Utilizes a compact surface-mount package suitable for space-constrained designs

Applications

• High-resolution data acquisition systems requiring stable reference voltages
• Industrial process control instrumentation
• Medical equipment signal conditioning circuits

Procurement Notes

Verify the specific suffix IDGKT corresponds to the VSSOP-8 package and tape-and-reel delivery format. Confirm that the 4 V output variant matches the system requirements, as the REF6041 family includes other voltage options. Ensure compatibility with the intended operating temperature range and check for moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when a 4 V reference is required alongside tight tolerance specifications. Compare against the REF6030 or REF6025 if different output voltages are needed while maintaining similar drift characteristics. Consider the REF50xx series if lower noise performance is critical, noting the trade-offs in input voltage headroom and quiescent current consumption for the specific application topology.

Part Context

This part belongs to the REF60xx family of precision voltage references from Texas Instruments. The family shares common architectural features such as low drift and shutdown modes but varies in output voltage and specific electrical parameters. The REF6041 specifically targets applications needing a 4 V rail with high thermal stability.

Replacement Considerations

Direct substitutes include other REF60xx variants like REF6030 or REF6025 for different voltage levels. Cross-family alternatives may include the REF50xx series for lower noise or REF61xx series for buffered outputs, provided pinout and electrical constraints align.
