Texas Instruments presents a precision virtual ground whose output voltage is always equal to one-half the input voltage, the TLE2426 rail splitter. Voltage − V description 6 4 VO 2 The unique combination of a high-performance, micropower operational amplifier and a precision0 trimmed divider on a single silicon chip results in 0 0.25 0.5 0.75 1 a precise VO/VI ratio of 0.5 while sinking and t − Time − s sourcing current. The TLE2426 provides a low-impedance output with 20 mA of sink and source capability while drawing less than 280 µA of supply current over the full input range of 4 V to 40 V. A designer need not pay the price in terms of board space for a conventional signal ground consisting of resistors, capacitors, operational amplifiers, and voltage references. For increased performance, the 8-pin package provides a noise-reduction pin. 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-V or 12-V system is better than 1% over the full 40-V input range. Ripple rejection exceeds 12 bits of accuracy. Whether the application is for a data acquisition front end, analog signal termination, or simply a precision voltage reference, the TLE2426 eliminates a major source of system error.
