REF54410CDR

Overview

The REF54410CDR is a precision series voltage reference from the Texas Instruments REF54 family, providing a fixed output of 4.096V in an 8-pin SOIC package. It features a maximum temperature drift coefficient of 1 ppm/°C (C grade) and high initial accuracy of ±0.02%. The device operates with a wide input voltage range up to 18V and supports bidirectional load currents of ±10mA. Key electrical characteristics include a maximum quiescent current of 300µA at 25°C and low-frequency noise of 0.45ppm p-p. It is designed for stable operation with output capacitors between 1µF and 100µF.

Feature Summary

• High precision performance with low temperature drift and high initial accuracy
• Wide operating input voltage range supporting diverse power supply conditions
• Bidirectional output current capability for sourcing and sinking loads
• Integrated enable control for flexible power management

Applications

• Semiconductor test equipment
• Precision data acquisition systems
• Industrial instrumentation
• PLC analog I/O modules
• Field transmitters

Procurement Notes

Verify the specific suffix 'CDR' corresponds to the C-grade temperature range (0°C to 70°C) and SOIC-8 package configuration. Confirm that the application environment remains within the specified thermal limits to maintain the guaranteed 1 ppm/°C drift specification. Ensure proper decoupling capacitors are utilized as recommended in the datasheet to ensure stability.

Selection Notes

Select this component when a 4.096V reference is required with strict drift limitations in commercial temperature ranges. Consider the REF54410QDR if operation below 0°C or above 70°C is necessary, as it offers extended temperature coverage. Evaluate the ceramic LCCC package option if superior long-term stability is critical for the design.

Part Context

The REF54410CDR belongs to the REF54 family of high-precision voltage references designed to complement high-resolution data converters. This family emphasizes low noise and low drift characteristics suitable for demanding measurement applications. The device serves as a stable voltage source for analog-to-digital and digital-to-analog conversion stages in industrial and scientific instruments.

Replacement Considerations

REF54410QDR provides equivalent functionality with an extended temperature range (-40°C to +125°C). REF54410CFKHT offers improved long-term stability using a ceramic LCCC package. Both alternatives maintain pin compatibility with the REF54410CDR when the EN pin is not utilized.
