ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Junction Temperature of T A = 25°C only; limits applying over the full
Operating Junction Temperature range are denoted by a “?”. Minimum and Maximum limits are guaranteed through test,
design, or statistical correlation. Typical values represent the most likely parametric norm at T A = 25°C, and are provided
for reference purposes only. Unless otherwise indicated, I K = 10mA V K = V REF .
