Typical Performance Characteristics
37
HGNDA
GND
HV
Output stage A high voltage supply ground. A separate ground pin connection is provided
for each of the output stages. All of the HGND[A:D] pins connect to system “HV” power
ground (also see Note 8).

HVDDA
P
HV
Output stage A high voltage supply power. A separate power pin connection is provided
for each of the output stages. All of the HVDD[A:D] pins and the VDDHV pin connect to
the system “HV” power source.
NOTES:
7. Unless otherwise specified all pin names are active high. Those that are active low have an “n” prefix, such as nERRORA.
8. Thermal pad is internally connected to all 4 HGND ground pins (HGNDA, HGNDB, HGNDC, HGNDD). Any connection to the
thermal pad must be made to the common ground for these 4 ground pins.
