REF6241IDGKT

Overview

The REF6241IDGKT is a series voltage reference IC manufactured by Texas Instruments, housed in an 8-VSSOP package. It provides a fixed output voltage of 4.096V with an initial accuracy tolerance of ±0.05%. The device operates within an input voltage range of 4.35V to 5.5V and draws a supply current of 1.1mA. It delivers a maximum output current of 4mA. Key performance metrics include a temperature coefficient of 3ppm/°C and low noise characteristics of 3µVp-p from 0.1Hz to 10Hz. The component is rated for operation between 0°C and 70°C.

Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Features low temperature coefficient for stable performance across operating conditions
• Exhibits low noise profile suitable for sensitive analog signal chains
• Designed for surface-mount integration in compact electronic assemblies

Applications

• High-resolution data acquisition systems requiring precise reference voltages
• Industrial process control instrumentation
• Medical equipment signal conditioning circuits
• Precision measurement devices

Procurement Notes

Verify the specific suffix IDGKT corresponds to the 8-VSSOP package and tape-and-reel packaging format. Confirm that the 0°C to 70°C industrial temperature range aligns with system requirements, as other variants may offer extended ranges. Ensure compatibility with standard 8-pin VSSOP footprints during PCB layout. Check for RoHS3 compliance status if required by regional regulations.

Selection Notes

Select this component when a 4.096V reference is needed with ±0.05% accuracy. Consider the 1.1mA supply current for power budget calculations. The 3ppm/°C drift rate is critical for applications requiring minimal thermal compensation. Compare against other REF62xx family members if different output voltages or wider temperature ranges are necessary. Ensure the 4mA load capability meets downstream circuit demands.

Part Context

This part belongs to the REF62xx series of precision voltage references from Texas Instruments. These devices are designed for applications demanding high accuracy and stability. The REF6241 specifically offers a 4.096V output, distinguishing it from other variants like the REF6230 (3.0V) or REF6250 (5.0V). All share similar low-noise and low-drift characteristics but differ in output voltage and sometimes temperature range specifications.

Replacement Considerations

Direct substitutes within the same package and voltage include other REF6241 variants with different suffixes indicating packaging or temperature range changes. Cross-family replacements require matching the 4.096V output, ±0.05% accuracy, and 8-VSSOP footprint. Verify pinout compatibility before substitution.
