TLE2425 Precision Virtual Ground

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 Instruments has eliminated all of those components wi.

Features

ased 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-performance 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. ∆VV)O− Output Voltage Change − µV 100 VI = 5 V 80 60 TA = − 40°C 40 TA = 0°C TA = − 55°C 20 0 TA = 25°C − 20 TA = 125°C TA = 25°C − 40 − 60 TA = 125°C .
