Characteristics
4.3.1
Note:
Supply Section
The electrical characteristics involve the spread of values within the specified supply voltage and junction
temperature range T_J from – 25 C to 125 C. Typical values represent the median values, which are
related to 25°C. If not otherwise stated, a supply voltage of V_CC = 18 V is assumed.
