TLE2425IDRG4

Overview

The TLE2425IDRG4 is a precision virtual ground reference IC manufactured by Texas Instruments, designed for single-supply analog systems. It provides a stable 2.5V output with an operating temperature range of -40°C to 85°C. The device features a maximum input voltage of 40V and typical bias current of 170µA. It offers high output current capability of 20mA, low output impedance of 7.5mΩ, and excellent regulation characteristics including 1.5µV/V input regulation. Packaged in an 8-pin SOIC (D) format, it integrates a micropower voltage reference and operational amplifier.

Feature Summary

• Integrates a precision micropower voltage reference and high-performance operational amplifier on a single silicon chip
• Provides increased dynamic signal range and improved signal-to-noise ratio in single-supply applications
• Features low output impedance and excellent load and input regulation exceeding 12-bit accuracy
• Includes a macromodel for circuit simulation

Applications

• Signal-conditioning front ends for data acquisition systems
• Providing reference voltages for ADC and DAC interfacing
• Generating offsets for data converters
• Terminating signal grounds in single power source analog circuits

Procurement Notes

Verify the specific suffix 'RG4' indicates tape and reel packaging within the SOIC-8 package. Confirm the 'I' suffix corresponds to the industrial temperature range of -40°C to 85°C. Ensure compatibility with standard surface-mount assembly processes for the D package outline. Cross-reference the manufacturer part number against official distribution channels to confirm active production status and RoHS compliance details.

Selection Notes

Select this component when designing single-supply analog circuits requiring a precise mid-rail reference without external discrete components. It is suitable for applications demanding low noise and high stability over the industrial temperature range. Consider the 20mA output current capability for driving moderate loads directly. Evaluate the need for the taped and reeled packaging format for automated assembly lines versus tube packaging.

Part Context

The TLE2425 series serves as a dedicated solution for creating virtual grounds in 5V/GND analog systems. It replaces traditional resistor-capacitor-opamp configurations, reducing board space and system error sources. The ID variant specifically targets industrial environments, offering extended temperature performance compared to commercial grades while maintaining the same electrical specifications for precision referencing.

Replacement Considerations

TLE2425IDR is the tube-packaged equivalent of the same device.
