OUTPUT REGULATION

In 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.
