description/ordering information

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.

INPUT/OUTPUT TRANSFER CHARACTERISTICS

The unique combination of a high-performance,

micropower operational amplifier and a precision-

trimmed divider on a single silicon chip results in

a precise V /V 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. For increased

performance, the 8-pin package provides a

noise-reduction pin. With the addition of an

0.25

0.5

t − Time − s

0.75

external capacitor (C ), 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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
