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).

38

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.
