The gain -10 and +11 precision amplifier circuit diagram

Published:2011/6/28 4:26:00 Author:Rebekka | Keyword: precision amplifier | From:SeekIC

Gain + 11 precision amplifier circuit is shown in figure (b). The amplifier circuit has input impedance high magnification and the voltage is high. The voltage magnification is decided by: Av = type (1 + R2 / R1) = (1 + 100/10) = 1, the maximum gain error of the above two circuits is about 0.01%, The biggest nonlinear error is about 0.001%, the gain drift is about 2 x 10-6 / ℃.
