Supply Section
Note: The electrical characteristics involve the spread of values guaranteed within the specified supply voltage
and junction temperature range TJ from – 25 oC to 125oC. Typical values represent the median values,
which are related to 25°C. If not otherwise stated, a supply voltage of VCC = 18 V is assumed.
