... PNP Output The output of the LT1782 can swing to within 60mV of the positive rail with no load and within 3mV of the negative rail with no load. When monitoring voltages within 60mV of the positive rail or within 3mV of the negative rail, gain should be taken to keep the output from clipping. The ...

... APPLICATIO S I FOR ATIO sourcing current is reduced to 10mA at 3V total supplies as noted in the Electrical Characteristics. The LT1782 is internally compensated to drive at least 600pF of capacitance under any output loading condi- tions. A 0.22 F capacitor in series with a 150 resistor between the output and ground will compensate these amplifiers for larger capacitive loads 10,000pF, at all output currents ...
