TLE2425IDR

Overview

The TLE2425IDR is a precision virtual ground integrated circuit manufactured by Texas Instruments, designed to provide a stable reference voltage for single-supply analog systems. It operates within an input voltage range of 4 V to 40 V and delivers a fixed output voltage of 2.5 V with a tolerance of ±0.8%. The device features a typical bias current of 170 µA and supports a maximum output current of 20 mA. It is housed in an 8-pin SOIC (D) package and is rated for operation over an industrial temperature range of -40°C to +85°C.

Feature Summary

Integrates a micropower voltage reference and high-performance operational amplifier into a single silicon chip
Provides excellent regulation characteristics including low output impedance and high ripple rejection
Eliminates the need for external resistors, capacitors, and discrete op-amps typically required for virtual ground generation

Applications

Signal-conditioning applications using single power sources
Data acquisition system front ends requiring 12-bit accuracy or higher
Interfacing with ADCs and DACs to improve signal-to-noise ratio and reduce distortion

Procurement Notes

Verify the specific suffix 'IDR' corresponds to the industrial temperature grade (-40°C to +85°C) and tape-and-reel packaging format. Confirm RoHS compliance status and lead finish details against the latest manufacturer documentation prior to integration. Ensure input voltage constraints are strictly observed to maintain specified regulation performance.

Selection Notes

Select this component when a precise 2.5V mid-rail reference is required for 5V single-supply analog circuits. The I-suffix ensures suitability for industrial environments compared to commercial variants. Consider the 20mA output capability for driving moderate loads without external buffering. Verify that the SOIC package dimensions align with the target PCB footprint.

Part Context

This part belongs to the TLE2425 family of precision virtual grounds from Texas Instruments. The family includes variants with different temperature ratings (C, I, M) and packages (SOIC, TO-92). The TLE2425IDR specifically denotes the industrial temperature range version in surface-mount SOIC packaging, offering a compact solution for replacing discrete virtual ground circuits.
