REF6041IDGKR

Overview

The REF6041IDGKR is a high-precision series voltage reference from Texas Instruments, providing a fixed output of 4.096 V. It features an initial accuracy of ±0.05% and a temperature coefficient of 5 ppm/°C. The device integrates an ADC drive buffer and operates with a maximum input voltage of 5.5 V. It supports a maximum shunt current of 4 mA and consumes 1.1 mA of supply current. The component is housed in an 8-pin VSSOP package (VSSOP-8-0.65mm) and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrated ADC drive buffer for direct interface with analog-to-digital converters
• High precision with low temperature drift ensuring stable reference performance
• Fixed output voltage configuration eliminating external resistor networks

Applications

• Precision data acquisition systems requiring stable voltage references
• Industrial process control instrumentation
• Medical equipment signal conditioning circuits

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature range specifications. Confirm that the VSSOP-8 footprint matches the design layout. Check manufacturer documentation for specific handling and storage requirements related to surface-mount components.

Selection Notes

Select this component when a fixed 4.096 V reference with high accuracy is required. Consider the integrated buffer if driving capacitive loads or ADC inputs directly. Ensure the 5.5 V maximum input voltage aligns with the system power supply rails.

Part Context

This part belongs to the REF6041 series of high-precision voltage references. It shares family characteristics such as integrated buffering and low noise but differs in output voltage and specific package options compared to other variants like the REF6033 or REF6025.

Replacement Considerations

Direct substitutes include REF6041IDGKT and REF6041IDGK. Verify pinout compatibility and thermal performance when replacing with these variants.
