TLE2425CLP

Overview

The TLE2425CLP is a precision virtual ground reference IC from Texas Instruments, designed for single-supply analog systems. It provides a stable 2.5V output voltage with an initial accuracy of ±0.8% at 25°C and a temperature coefficient of 20 ppm/°C. The device operates within an input voltage range of 4V to 40V and supports a typical bias current of 170 µA. It features high output-current capability, sourcing or sinking up to 20 mA typically, while maintaining low output impedance. The component is housed in a TO-92-3 (LP) package and is rated for commercial operation between 0°C and 70°C.

Feature Summary

• Integrates a micropower voltage reference and a high-performance operational amplifier into a single silicon chip to eliminate external components.
• Provides excellent regulation characteristics including low output impedance and superior input and load regulation exceeding 12 bits of accuracy.
• Delivers increased dynamic signal range, improved signal-to-noise ratio, and lower distortion compared to traditional resistor-capacitor solutions.

Applications

• Signal-conditioning front ends for data acquisition systems requiring precise grounding.
• Providing termination for all signal grounds in single power source analog circuits.
• Interfacing with ADCs and DACs to improve signal accuracy and reduce system error.

Procurement Notes

Verify the specific suffix 'CLP' corresponds to the commercial temperature grade (0°C to 70°C) and TO-92-3 package configuration. Confirm RoHS compliance status via the manufacturer's latest packaging addendum. Ensure the application input voltage remains within the 4V to 40V recommended operating conditions to maintain specified performance levels.

Selection Notes

Select this component when a fixed 2.5V virtual ground is required for 5V/GND analog systems. It serves as a direct replacement for discrete resistor and capacitor networks, simplifying design and reducing board space. Consider the TO-92-3 through-hole package for prototyping or applications where surface-mount options are not feasible.

Part Context

The TLE2425 series includes variants such as the TLE2425CD (SOIC), TLE2425ID (Industrial Temp), and TLE2425MD (Military Temp). The CLP variant specifically denotes the plastic TO-92-3 package with commercial temperature rating. This family is part of Texas Instruments' PMIC portfolio focused on precision voltage references.

FAQ

What is the maximum continuous input voltage allowed?

The absolute maximum continuous input voltage is 40 V.

Does the device support short-circuit protection?

Yes, the output can be shorted to either supply with unlimited duration, provided temperature and supply voltages are limited to ensure maximum dissipation ratings are not exceeded.
