Overview
The TLE2425CDR is a precision virtual ground integrated circuit manufactured by Texas Instruments, designed to provide a stable 2.5V reference for single-supply analog systems. It operates within an input voltage range of 4V to 40V and supports an operating temperature range of 0°C to 70°C. The device delivers a typical output current capability of 20mA with a bias current of 170µA. Key electrical characteristics include an output voltage tolerance of ±20mV at 25°C, a temperature coefficient of 20ppm/°C, and an output impedance of 7.5mΩ. It is housed in an 8-pin SOIC (D) package.
Feature Summary
- Combines a micropower voltage reference and high-performance operational amplifier into a single silicon chip
- Provides increased dynamic signal range and improved signal-to-noise ratio for single-supply applications
- Features excellent regulation characteristics including low output impedance and minimal drift
- Includes a macromodel for circuit simulation purposes
Applications
- Signal-conditioning front ends for data acquisition systems
- Providing termination for signal grounds in single power source circuits
- Interfacing with ADCs and DACs to eliminate system error sources
Procurement Notes
Verify the specific suffix 'CDR' corresponds to the commercial temperature grade (-2425C marking) and SOIC-8 tape-and-reel packaging. Confirm RoHS compliance and lead finish status via the latest Package Option Addendum. Ensure design requirements align with the 0°C to 70°C operating range specified for this variant.
Selection Notes
Select the TLE2425CDR when a precise 2.5V virtual ground is required for 5V/GND analog systems. This part replaces discrete resistor-capacitor-amplifier solutions, reducing component count and board space. Consider the 20mA sink/source capability and low noise characteristics for sensitive signal paths requiring high accuracy.
Part Context
The TLE2425 series serves as a dedicated solution for generating virtual grounds in single-supply electronics. The 'CDR' designation indicates the commercial temperature variant packaged in an SOIC format. It belongs to a family of precision references that simplify analog interface design by integrating regulation and amplification functions on one die.
Replacement Considerations
TLE2426CDR provides adjustable virtual ground capabilities. TLE2425IDR offers the same functionality with an extended industrial temperature range (-40°C to 85°C). Verify pinout compatibility and thermal performance when substituting.
