TYPICAL APPLICATIONS
This circuit shows how to use one LTC1446 to make an
autoranging ADC. The microprocessor sets the reference
span and the Common pin for the analog input by loading
the appropriate digital code into the LTC1446. V
controls the Common pin for the analog inputs to the
LTC1296 and V

off the PNP transistor supplying power to the LTC1446.
The resistor and capacitor on the LTC1446 outputs act as
a lowpass filter for noise.
