What are the key features of TLE2425CDG4?
- Precision 2.5 V virtual ground output with wide 4 V to 40 V input range for versatile single-supply to dual-supply conversion
- 20 mA output current capability with low output impedance for driving multiple analog loads simultaneously
- 8-pin SOIC package with industry-standard footprint enabling drop-in compatibility across generations of precision analog front-end designs
What is TLE2425CDG4 used for?
The TLE2425CDG4 is used to create a stable 2.5 V virtual ground reference in single-supply systems, enabling rail-to-rail op-amps to handle bipolar signals in audio, sensor, and instrumentation amplifier circuits. It simplifies power supply architecture in industrial field transmitters and data acquisition modules that must process both positive and negative signals from a single 5 V or 12 V rail. The 4 V to 40 V input range makes it compatible with 5 V logic systems as well as 24 V industrial supplies without additional components.

Frequently Asked Questions
How does the TLE2425CDG4 create a virtual ground and at what output voltage is it fixed?
The TLE2425CDG4 actively drives a precision 2.5 V output that serves as a virtual ground mid-rail, allowing single-supply op-amp circuits to process bipolar analog signals. The internal bandgap reference holds the 2.5 V output within ±2 mV across a 4 V to 40 V input range, providing a stable reference with load regulation better than 1 Ω effective output impedance for loads up to 20 mA.
Which industrial sensor front-end designs benefit from using the TLE2425CDG4 versus a resistive voltage divider?
4-20 mA loop transmitters, thermocouple amplifiers, and bridge sensor conditioners all benefit because the TLE2425CDG4 actively regulates the 2.5 V mid-rail against load variations up to 20 mA, unlike a passive resistor divider that shifts by tens of millivolts per milliamp of load. In a 12-bit ADC front-end operating from a 5 V rail, this active regulation prevents mid-rail drift that would otherwise consume 3-4 bits of dynamic range.
What is the maximum input voltage the TLE2425CDG4 can accept and how does this affect 24 V industrial designs?
The TLE2425CDG4 accepts input voltages from 4 V to 40 V, covering standard 24 V industrial rails with margin for transient spikes up to 40 V. This allows direct connection to 24 V bus-powered field devices without a pre-regulator, simplifying the BOM and reducing the power conversion stages in PLCs, smart transmitters, and building automation controllers.
How much output current can the TLE2425CDG4 supply and how many op-amp inputs can it bias simultaneously?
The TLE2425CDG4 delivers up to 20 mA of continuous output current. Since a typical precision op-amp bias input draws under 10 µA, a single TLE2425CDG4 can simultaneously bias hundreds of op-amp non-inverting inputs in a large analog signal chain, or drive moderate-impedance resistive networks establishing the virtual ground mid-point across multiple channels in a data acquisition card.
For a portable 9 V battery instrument, how does the TLE2425CDG4 split the supply and what headroom remains for analog signal swing?
Connected to a 9 V battery, the TLE2425CDG4 fixes the virtual ground at 2.5 V, leaving +6.5 V above and -2.5 V below the mid-rail. Rail-to-rail op-amps biased from this mid-point can swing ±2 V with typical headroom, covering the ±1 V output range of most MEMS sensors and providing adequate gain for a ±100 mV bridge sensor input through a 10× gain stage.
