General Description

Voltage − V In signal-conditioning applications utilizing a single power source, a reference voltage equal to one-half the supply voltage is required for termination of all analog signal grounds.

Texas Instruments presents a precision virtual ground whose output voltage is always equal to one-half the input voltage, the TLE2426 rail splitter.

6 4 VO 2 The unique combination of a high-performance, micropower operational amplifier and a precision- trimmed divider on a single silicon chip results in a precise VO/VI ratio of 0.5 while sinking and sourcing current.
