REF6150IDGKR

Overview

The REF6150IDGKR is a high-precision voltage reference from Texas Instruments featuring an integrated high-bandwidth buffer. It delivers a fixed 5 V output with an initial accuracy of 0.05% and a maximum temperature coefficient of 8 ppm/C. The device operates within a supply voltage range of 5.3 V to 5.5 V, drawing a typical quiescent current of 830 uA. It supports a maximum output current of 3 mA and includes a shutdown mode with a typical current of 1 uA. Noise performance is characterized by 5 uVrms in the 10 Hz to 10 kHz band and 15 uVpp in the 0.1 Hz to 10 Hz band. It is housed in an 8-VSSOP package and rated for operation between -40°C and 125°C.

Feature Summary

• Integrated low output impedance buffer for high drive capability
• High precision with 0.05% initial accuracy and low temperature drift
• Ultra-low power consumption with dedicated shutdown functionality

Applications

• Precision data acquisition systems
• Medical instrumentation requiring stable references
• Industrial process control loops

Procurement Notes

Verify the suffix 'KR' indicates tape-and-reel packaging when ordering. Confirm the specific grade matches the required temperature coefficient and accuracy specifications. Ensure the operating environment stays within the -40°C to 125°C range. Check for moisture sensitivity level requirements during storage and handling. Validate that the 5.3 V minimum input voltage aligns with the system power supply design.

Selection Notes

Select this component when a buffered output is necessary to drive capacitive loads without oscillation. Compare noise specifications against ADC requirements for signal integrity. Consider the 830 uA quiescent current for battery life calculations if not using shutdown mode. Evaluate the 8-VSSOP footprint against available PCB space constraints.

Part Context

This part belongs to the REF61xx series of high-precision voltage references. It shares the same core architecture as the REF6150IDGKT but differs in packaging format. The series is designed for applications demanding stability and low noise in compact form factors.

Replacement Considerations

The REF6150IDGKT is the tray-packaged equivalent of this reel-part. Other REF61xx variants offer different output voltages or accuracy grades but may lack the integrated buffer.
