REF6141IDGKT

Overview

The REF6141IDGKT is a high-precision series voltage reference from Texas Instruments, providing a fixed output of 4.096 V with an initial accuracy of ±0.05%. It features a low temperature coefficient of 8 ppm/°C and operates within a supply voltage range of 2.7 V to 5.5 V. The device draws a typical quiescent current of 350 µA and supports a maximum load current of 4 mA. Housed in an 8-pin VSSOP package, it functions reliably across an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Integrated low-output impedance buffer for stable driving capabilities
• High precision performance with tight initial accuracy tolerance
• Low temperature coefficient ensuring stability across thermal variations
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• Automatic test equipment (ATE)
• Precision data acquisition systems
• Medical devices
• Programmable logic controller (PLC) analog input modules

Procurement Notes

Verify the specific suffix IDGKT confirms the 8-VSSOP package and tape-and-reel or cut-tape availability. Confirm RoHS compliance status matches project requirements. Ensure the supplier source provides genuine Texas Instruments components to guarantee specified electrical parameters. Check for any specific handling precautions related to electrostatic discharge during assembly.

Selection Notes

Select this component when a fixed 4.096 V reference is required with high accuracy and low drift. It is suitable for applications needing a buffered output to drive ADCs or DACs directly without external buffering. Consider the 8-VSSOP package size for PCB layout constraints. Evaluate power consumption against system battery life requirements given the 350 µA quiescent current.

Part Context

This part belongs to the REF61xx family of high-precision voltage references from Texas Instruments. These devices are designed for applications requiring stable and accurate voltage sources. The REF6141 specifically offers a 4.096 V output, distinguishing it from other variants like the REF6130 (3 V) or REF6133 (3.3 V) within the same series.

Replacement Considerations

Public confirmed substitute part numbers include REF6141IDGKR.
