ELECTRICAL CHARACTERISTICS The q denotes specifications which apply over the full operating temp-
erature range, otherwise specifications are at TA = 25°C. VS = ±6V, VCM = 0V, nominal mode with a 13k resistor from CTRL1 to Vand
a 49.9k resistor from CTRL2 to V , pulse power tested unless otherwise noted. (Note 9)
