Datasheet - Electrical Characteristics
6 Electrical Characteristics
VDD = 2.7 to 5.5V, RSET = 9.53kΩ, Typical values are at TAMB = +25°C, VDD = 5.0V (unless otherwise specified). All limits are guaranteed. The
parameters with min and max values are guaranteed with production tests or SQC (Statistical Quality Control) methods.
