4.3 Characteristics
4.3.1
Note:
Supply Section
The electrical characteristics involve the spread of values guaranteed within the specified supply voltage
and junction temperature range T_J from – 25 ^oC to 125^oC. Typical values represent the median values,
which are related to 25°C. If not otherwise stated, a supply voltage of V_CC = 15 V is assumed.
