Pins connection (top view)
Channel 1 LS driver supply: it can be varied from 5V to 12V buses.
It must be connected together with other VCCDRx pins.
Filter locally with at least 1 F ceramic cap vs. PGND1.
Channel 1 LS driver output.
A little series resistor helps in reducing device-dissipated power.
Channel 1 LS driver return path.
Connect to Power Ground Plane.
Device supply voltage. The operative supply voltage is 12V ±15%.
Filter with 1 F capacitor (Typ.) vs. SGND.
All the internal references are referred to this pin. Connect it to the PCB signal ground.
Offset programming pin, internally fixed at 1.240V.
Short to SGND to disable the offset generation or connect through a resistor R
SGND to program an offset (positive or negative, depending on TC status) to the regulated
output voltage as reported in the relative section.
This pin is connected to the error amplifier output and is used to compensate the control
feedback loop.
