mance precision operational amplifier in a single IO – Output Current – mA
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.
