*Absolute Maximum Ratings are those values beyond which damage to the device
may occur. Functional operation under these conditions is not implied. Continuous
operation of the device at the absolute rating level may affect device reliability.
Operating Conditions*
Symbol
Parameter
Value
VPP
Positive high voltage supply
50V to 110V
VNN
Negative high voltage supply
-10V to VPP –220V
VDD
Logic power supply voltage
4.75V to 12.6V
VIH
High level input voltage
VDD -1.0V to VDD
VIL
Low level input voltage
0V to 1.0V
VSIG
Analog signal voltage peak-to-peak
VNN+10V to VPP-10V
TA
Operating free air temperature
0°C to 70°C
* Notes:
1 Power up/down sequence is arbitrary except GND must be powered-up first and powered-down last.
2 VSIG must be within VNN and VPP or floating during power up/down transition.
3 Rise and fall times of power supplies VDD, VPP, and VNN should not be less than 1.0msec.
