Noise Reduction Pin

description/ordering information
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.
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.
