... OUTPUT VOLTAGE (V) 1783 G26 W U Inputs The LT1783 has two input stages, NPN and PNP (see the Simplified Schematic), resulting in three distinct operat- ing regions as shown in the Input Bias Current vs Common Mode typical performance curve. For input voltages about 0.8V or more below V input stage is active and the input bias current is typically – ...

... Output The output of the LT1783 can swing to within 60mV of the positive rail with no load and within 3mV of the negative rail with no load. When monitoring input voltages within 60mV of the positive rail or within 3mV of the negative rail, gain should be taken to keep the output from clipping ...
