TLE2426CD (TEXAS INSTRUMENTS)

The TLE2426CD is a 'Rail Splitter' Precision Virtual Ground Voltage Reference for signal-conditioning applications utilizing a single power source. The precision virtual ground whose output voltage is always equal to one-half the input voltage. 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. It provides a low impedance output with 20mA of sink and source capability while drawing less than 280µA of supply current. With the addition of an external capacitor (CNR), peak-to-peak noise is reduced while line ripple rejection is improved. Initial output tolerance for a single 5 or 12V system is better than 1% with 3.6% over the full 40V input range. Ripple rejection exceeds 12 bits of accuracy.
