Precision Virtual Ground
Low-Impedance Output... 0.0075 Ω Typ Macromodel Included
descriptionIn signal-conditioning applications using a single
power source, a reference voltage is required for
termination of all signal grounds. To accomplish
this, engineers have typically used solutions
consisting of resistors, capacitors, operational
amplifiers, and voltage references. Texas Instru-
ments has eliminated all of those components
with one easy-to-use 3-terminal device. That
device is the TLE2425 precision virtual ground.
Use of the TLE2425 over other typical circuit
solutions gives the designer increased dynamic
signal range, improved signal-to-noise ratio,
lower distortion, improved signal accuracy, and
easier interfacing to ADCs and DACs. These
benefits are the result of combining a precision
micropower voltage reference and a high-perfor-
mance precision operational amplifier in a single
silicon chip. It is the precision and performance of
these two circuit functions together that yield such
dramatic system-level performance.
The TLE2425 improves input regulation as well as output regulation and, in addition, reduces output impedance
and power dissipation in a majority of virtual-ground-generation circuits. Both input regulation and load
regulation exceed 12 bits of accuracy on a single 5-V system. Signal-conditioning front ends of data acquisition
systems that push 12 bits and beyond can use the TLE2425 to eliminate a major source of system error.
AVAILABLE OPTIONS The D package is available taped and reeled. Add R suffix to
