REF6150IDGKT

Overview

The REF6150IDGKT is a high-precision voltage reference featuring an integrated high-bandwidth buffer, manufactured by Texas Instruments. It provides a fixed output voltage of 5 V 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 and draws a typical quiescent current of 830 uA. Key noise specifications include a typical wideband noise of 5 uVrms (10 Hz to 10 kHz) and low-frequency noise of 15 uVpp (0.1 Hz to 10 Hz). It supports a maximum output current of 3 mA and functions reliably across an operating temperature range of -40°C to 125°C in an 8-VSSOP package.

Feature Summary

• Integrated high-bandwidth buffer providing low output impedance for stable driving capabilities
• High precision performance characterized by tight initial accuracy and low temperature drift
• Low noise profile suitable for sensitive analog signal processing applications

Applications

• Precision data acquisition systems requiring stable reference voltages
• High-resolution analog-to-digital converter (ADC) references
• Medical instrumentation and test equipment calibration circuits

Procurement Notes

Verify the specific suffix 'DGKT' corresponds to the 8-VSSOP package and tape-and-reel shipping configuration. Confirm that the catalog rating matches the intended industrial or automotive qualification requirements if applicable. Ensure the input voltage remains strictly within the 5.3 V to 5.5 V operational window to maintain specified accuracy and stability parameters during system integration.

Selection Notes

Select this component when a 5 V reference with integrated buffering is required to minimize external component count and board space. The 8 ppm/°C temperature coefficient makes it suitable for applications demanding high thermal stability without complex trimming. Consider the 830 uA quiescent current consumption against power budget constraints compared to lower-power shunt references.

Part Context

This part belongs to the REF61xx series of high-precision voltage references from Texas Instruments. The series is designed to offer superior performance over standard references by integrating a buffer amplifier directly on the die. This integration reduces output impedance and improves transient response, distinguishing it from non-buffered counterparts like the REF50xx series which may require external amplification.

Replacement Considerations

The REF6250IDGKT offers similar functionality with a lower temperature coefficient of 3 ppm/°C but requires careful verification of pinout compatibility and specific noise characteristics before substitution.
