REF6141IDGKR

Overview

The REF6141IDGKR is a high-precision voltage reference from Texas Instruments featuring an integrated buffer and enable pin. It provides a fixed output of 4.096 V with an initial accuracy of ±0.05% and a temperature coefficient of 8 ppm/°C. The device operates within a supply voltage range of 4.35 V to 5.5 V, drawing a quiescent current of 4 mA. It is housed in an 8-pin VSSOP package (0.65 mm height) and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrated ADC drive buffer for direct signal conditioning
• High precision with ±0.05% initial accuracy
• Low temperature drift of 8 ppm/°C
• Built-in enable pin for power management

Applications

• Data acquisition systems requiring stable reference voltages
• Precision analog-to-digital converter (ADC) interfaces
• Medical instrumentation
• Industrial process control equipment

Procurement Notes

Verify the specific suffix 'IDGKR' corresponds to the tape-and-reel packaging format and the 4.096 V output variant. Confirm that the 8-VSSOP package dimensions match the PCB footprint requirements. Ensure the supply voltage remains within the 4.35 V to 5.5 V range during operation to maintain specified accuracy and stability.

Selection Notes

Select this component when a fixed 4.096 V reference with integrated buffering is required to simplify circuit design. It is suitable for applications needing low noise and high stability over a wide temperature range. Consider the 4 mA quiescent current if power consumption is a constraint compared to lower-power alternatives like the REF60xx series.

Part Context

This part belongs to the REF61xx family of high-precision voltage references from Texas Instruments. Unlike the REF60xx series which focuses on ultra-low power, the REF61xx series emphasizes higher precision and integrated buffering capabilities. It complements other TI references by offering a balance of accuracy and ease of use for driving ADCs directly.

Replacement Considerations

The REF6141IDGKT is the tray-packaged equivalent of this reel-part. For functional replacements, consider the REF6142IDGKR for a 2.5 V output or the REF6140IDGKR for a 2.048 V output, maintaining the same package and performance characteristics.
