The drivers can be supplied with HVP-HVM (dou-
ble supply mode) or with HVP-Ground (single
supply mode). In both cases they can achieve a
rail-to rail output dynamic range with an average
load current up to
±75mA.
In double supply mode the input stage has -
5V/+5V common mode dynamic range, while in
single supply configuration it has 1.2V up to 10V
input common mode dynamic range.

Input Multiplexer
MULTIPLEXER is controlled by internal logic with 3 digital inputs, supplied by IntVref (2.5V), it is com-
patible to 3.3V and 5V logic command signals, it allows to perform the following configuration:

F.E. = Falling Edge
The MUX is at NOT inv. Inputs, and NO current flows through the MUX switches, because the driver in-
put stage is designed with high impedance stage.
