REF6245IDGKT

Overview

The REF6245IDGKT is a series voltage reference IC manufactured by Texas Instruments, housed in an 8-VSSOP package. It provides a fixed output voltage of 4.5V with an initial accuracy tolerance of ±0.05%. The device operates within an input voltage range of 4.75V to 5.5V and draws a supply current of 1.15mA. It supports a maximum output current of 3.5mA and exhibits a temperature coefficient of 3ppm/°C. Low-frequency noise is specified at 3µVp-p from 0.1Hz to 10Hz. The component functions reliably across an ambient temperature range of 0°C to 70°C.

Feature Summary

• Delivers high-precision voltage regulation with tight initial accuracy tolerance for sensitive measurement circuits.
• Maintains stable output performance over varying thermal conditions through low temperature coefficient characteristics.
• Features low low-frequency noise profile suitable for precision analog-to-digital converter references.

Applications

• Precision data acquisition systems requiring stable reference voltages
• High-resolution analog-to-digital converter (ADC) front-end circuits
• Industrial instrumentation signal conditioning stages

Procurement Notes

Verify the specific suffix IDGKT corresponds to the 8-VSSOP surface-mount package configuration. Confirm that the 0°C to 70°C operating temperature range meets your environmental requirements, as other variants may support wider industrial ranges. Ensure input voltage stays within the 4.75V to 5.5V specification to maintain rated accuracy and stability during operation.

Selection Notes

Select this component when a 4.5V fixed reference is required with high initial accuracy. Consider the 8-VSSOP package constraints for board space. Evaluate if the 0°C to 70°C commercial temperature range suffices, or if a wider range variant like the REF62xx family's extended options is needed. Compare power consumption against system budget constraints given the 1.15mA supply current.

Part Context

This part belongs to the Texas Instruments REF62xx series of high-precision voltage references. The series is designed for applications demanding low drift and low noise. The REF6245 specifically targets the 4.5V output niche within this portfolio, sharing architectural similarities with other members like the REF6230 and REF6250 while differing in output voltage and specific electrical parameters.

Replacement Considerations

The REF6245IDGKR serves as the reel-pack equivalent of this cut-tape component. Other REF62xx family members offer different output voltages but share similar pinouts and functionality. Verify package compatibility when substituting with generic equivalents.
