Packages Only)
descriptionIn 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. T exas
Instruments 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 precision-
trimmed 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 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. The performance and precision of the TLE2426 is available in an easy-to-use, space saving,
3-terminal LP package. For increased performance, the optional 8-pin packages provide 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% with 3.6% 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.
