REF6245IDGKR

Overview

The REF6245IDGKR is a high-precision series voltage reference manufactured by Texas Instruments, featuring a fixed output of 4.5 V with an initial accuracy of ±0.05%. It exhibits a low temperature coefficient of 3 ppm/°C and operates within an input voltage range of 4.75 V to 5.5 V. The device draws a supply current of 1.15 mA and supports a maximum load current of 3.5 mA. It is housed in an 8-VSSOP package and is rated for operation between -40°C and +125°C.

Feature Summary

• Delivers stable 4.5 V reference with ±0.05% initial accuracy
• Maintains low drift rate of 3 ppm/°C across temperature range
• Operates on single supply from 4.75 V to 5.5 V
• Provides 3.5 mA output drive capability

Applications

• High-resolution data acquisition systems
• Precision analog-to-digital converter references
• Medical instrumentation signal conditioning
• Industrial process control sensors

Procurement Notes

Verify the suffix 'KR' indicates tape-and-reel packaging when ordering. Confirm the specific voltage variant matches system requirements, as the REF62xx family includes multiple output options. Ensure ESD handling protocols are followed due to the sensitive semiconductor nature of the component. Cross-reference the manufacturer part number with distributor codes to avoid substitution errors during procurement.

Selection Notes

Select this component when a 4.5 V output is required with tight tolerance specifications. Compare against other REF62xx variants if different voltage levels or noise characteristics are needed. Consider the 8-VSSOP package constraints for PCB layout. Verify that the 1.15 mA quiescent current fits the power budget of the application design.

Part Context

This part belongs to the REF62xx series of precision voltage references from Texas Instruments. The series is designed for applications requiring high accuracy and low drift. The IDGKR suffix denotes the specific package type and reel quantity configuration provided by the manufacturer for automated assembly processes.

Replacement Considerations

REF6245IDGKT serves as the cut-tape equivalent of the same electrical specification. Other REF62xx models may replace this unit if different output voltages are acceptable. Verify pinout compatibility before substituting with non-series components.
