To accomplish this, engineers have typically used solutions consisting of resistors, capacitors, operational amplifiers, and voltage references. Texas Instruments has eliminated all of those components with one easy-to-use 3-terminal device. That device is the TLE2425 precision virtual ground. 60 40 20 0 TA = 25C - 20 TA = - 40C TA = - 55C TA = 0C TA = 125C TA = 25C Use of the TLE2425 over other typical circuit - 40 solutions gives the designer increased dynamic TA = 125C - 60 signal range, improved signal-to-noise ratio, TA = - 55C lower distortion, improved signal accuracy, and - 80 easier interfacing to ADCs and DACs. These - 100 benefits are the result of combining a precision 0 24 8 10 - 10 - 8 - 6 - 4 - 2 6 micropower voltage reference and a high-perforIO - Output Current - mA 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. The TLE2425C is characterized for operation from 0C to 70C. The TLE2425I is characterized for operation from - 40C to 85C. The TLE2425M is characterized for operation over the full military temperature range of -55C to 125C.
