DIFFERENTIAL_PREAMP

Published:2009/7/9 5:23:00 Author:May | From:SeekIC

Opamps A1 and A2 form cross-coupled preamp with differential input and differential output, driving instrumentation opamp A3 to provide overall gain of 106. Common-mode input range is ±10 V, and full.scale differential input is ±100 mV. For higher input impedance, 108 opamps can be used in preamp. For higher speed, all three opamps can be 118.-W. G.
