TLE2426CDRG4

Overview

The TLE2426CDRG4 is a ground reference (virtual ground) voltage reference IC manufactured by Texas Instruments. It operates within an input voltage range of 4V to 40V and provides an adjustable output voltage between 2V and 20V. The device features an initial accuracy of ±1% and a typical temperature coefficient of 35ppm/°C. It supports a maximum output current of 20mA with a supply current of 400µA. The component is housed in an 8-SOIC package and is rated for operation from -55°C to +125°C.

Feature Summary

• Provides a stable virtual ground potential for single-supply systems
• Adjustable output voltage allows flexible circuit configuration
• High precision with low temperature drift characteristics

Applications

• Single-supply operational amplifier biasing
• Analog-to-digital converter reference circuits
• Signal conditioning stages requiring mid-rail reference

Procurement Notes

Verify the specific suffix 'CDRG4' against the official datasheet to confirm the commercial grade temperature range and tube packaging format. Ensure the design accounts for the 35ppm/°C temperature coefficient rather than assuming lower values found in other variants. Confirm RoHS compliance status matches current regulatory requirements before finalizing procurement.

Selection Notes

Select this component when a precise virtual ground is required for single-supply analog applications. The adjustable output range accommodates various rail voltages up to 40V. Consider the 8-SOIC package constraints for PCB layout. Verify that the 20mA load capability meets the downstream circuit demands without exceeding thermal limits.

Part Context

This part belongs to the TLE2426 series of virtual ground generators. It serves as a cost-effective alternative to dedicated dual-supply configurations. The series is widely used in audio and instrumentation applications where a clean mid-point reference is critical for signal integrity and noise reduction.

Replacement Considerations

TLE2426CDG4 is a direct pin-compatible substitute within the same series offering identical electrical specifications.
