analog input
input types
The four analog inputs can be configured as two pairs of differential inputs or four single-ended inputs by setting
the control register 0 bit 4 input type selection (dual or single channel).
differential input (CR0.4=1)
Up to two channels are available when the TLV1562 is programmed for differential input. The output data format
is bipolar when the device is operated in differential input mode.
single-ended input (CR0.4=0)
Up to four channels are available when the TLV1562 is programmed for single-ended input. The output data
format is unipolar when the device is operated in single-ended input mode.
