TLE2426CDR

Overview

The TLE2426CDR is a precision voltage reference IC from Texas Instruments, housed in an 8-pin SOIC surface-mount package. It operates as a rail-to-rail virtual ground or adjustable reference with an output range of 1.98 V to 20.2 V. Key electrical specifications include an initial accuracy of 1%, a temperature coefficient of 35 ppm/°C, and a maximum input voltage of 40 V. The device supports a maximum shunt current of 20 mA and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides stable rail-to-rail virtual ground functionality for single-supply systems
• Delivers precise voltage referencing with low temperature drift characteristics
• Supports high input voltage tolerance up to 40 V for flexible power configurations

Applications

• Single-supply operational amplifier biasing
• Precision analog signal conditioning circuits
• Data acquisition system reference generation

Procurement Notes

Verify the specific suffix 'CDR' indicates the tape-and-reel packaging variant distinct from the tube-packaged 'CD'. Confirm RoHS compliance status and ensure the supplier provides official Texas Instruments documentation matching the exact part number to avoid substitution errors with similar family members.

Selection Notes

Select this component when a reliable mid-supply reference or virtual ground is required for single-supply op-amp circuits. Consider the 1% initial accuracy and 35 ppm/°C temperature coefficient against application stability needs. Ensure the 20 mA load capability meets circuit demands and that the SOIC-8 package fits the PCB layout constraints.

Part Context

This part belongs to the TLE2426 series of dual rail-to-rail virtual ground generators. It serves as a cost-effective solution for creating split supplies from a single source. The device simplifies design by integrating two independent reference outputs in a compact surface-mount package, widely used in portable and battery-powered instrumentation.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pin-out compatibility and electrical parameter overlaps before considering alternative manufacturers or different Texas Instruments families.
