NOISE REDUCTION

NC − No internal connection
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. TI
presents a precision virtual ground whose output
voltage is always equal to one-half the input
voltage—the TLE2426 rail splitter.

Voltage − V
The unique combination of a high-performance,
micropower operational amplifier and a precisiontrimmed divider on a single silicon chip results in
a precise VO/VI ratio of 0.5 while sinking and
sourcing current. The TLE2426 provides a lowimpedance 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.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum
dissipation rating is not exceeded.
2. Long-term high-temperature storage and/or usage at the absolute maximum ratings may result in a reduction of overall device life.
