REF6241IDGKR

Overview

The REF6241IDGKR 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 features a low temperature coefficient of 3ppm/°C and exhibits a noise level of 3µVp-p over the 0.1Hz to 10Hz frequency band. The component supports a maximum output current of 4mA and functions reliably across a commercial operating temperature range of 0°C to 70°C.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial accuracy tolerance
• Maintains stable performance through ultra-low temperature coefficient characteristics
• Ensures signal integrity via minimal low-frequency noise generation

Applications

• High-resolution data acquisition systems requiring precise reference voltages
• Industrial process control instrumentation demanding long-term stability
• Medical diagnostic equipment utilizing sensitive analog front-ends
• Precision metering applications for accurate energy measurement

Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging configuration distinct from the 'T' variant. Confirm the 8-VSSOP physical footprint matches the target PCB layout constraints. Ensure the commercial temperature grade meets the operational environment requirements. Validate RoHS compliance status against current regulatory standards before integration into final assemblies.

Selection Notes

Select this component when a 4.096V reference is required with stringent accuracy needs. Consider the 1.1mA supply current for power-sensitive designs. Evaluate the 8-VSSOP package size against available board space. Compare the 3ppm/°C drift against environmental temperature variations to ensure system-level precision targets are achievable without external compensation.

Part Context

This part belongs to the REF62xx family of precision voltage references from Texas Instruments. It shares architectural similarities with other members like the REF6250 but differs in output voltage and specific electrical parameters. The VSSOP packaging allows for compact surface-mount integration in modern electronic devices requiring small form factors.

Replacement Considerations

Direct substitutes include the REF6241IDGT for reel-to-reel processing differences. Cross-reference the REF6250IDGKT if a 5V output is acceptable. Verify pin compatibility and thermal characteristics when replacing with generic equivalents from other manufacturers.
