Overview
The TLE2426CDG4 is a precision virtual ground generator manufactured by Texas Instruments, designed to create a stable mid-supply reference for single-supply analog circuits. It operates within an input voltage range of 4V to 40V and provides an adjustable output voltage from 2V to 20V. The device features an initial accuracy of 1% and a temperature coefficient of 35 ppm/°C. It supports a maximum shunt current of 20mA with a supply current of 400µA. Packaged in an 8-SOIC surface-mount format, it functions as a low-impedance rail splitter.
Feature Summary
- Generates a precise virtual ground at half the supply voltage for single-supply systems
- Provides low output impedance to maintain stability under varying load conditions
- Operates reliably across extended industrial temperature ranges
Applications
- Single-supply operational amplifier biasing
- Audio signal conditioning circuits
- Sensor interface power management
Procurement Notes
Verify that the specific part number matches the required package type and temperature grade for your application. Confirm RoHS compliance status and check for any recent product change notifications or lifecycle notices from the manufacturer before finalizing procurement decisions.
Selection Notes
Select this component when a stable, low-impedance reference point is needed for single-supply analog designs. Ensure the input voltage remains within the specified 4V to 40V range to guarantee proper operation and accuracy. Consider the thermal performance and packaging requirements relative to the PCB layout constraints.
Part Context
This component belongs to the TLE2426 series of virtual ground generators from Texas Instruments. It serves as a specialized power management IC alternative to passive resistor divider networks, offering superior load regulation and lower output impedance for precision analog applications.
Replacement Considerations
Direct substitutes include other variants within the TLE2426 family such as TLE2426CDR or TLE2426IDG4, provided they match the required package and temperature specifications.
