3. CHARACTERISTICS AND SPECIFICATIONS
3.1
Electrical Characteristics
Typical characteristics conditions:
T A = 25°C, V DD = 13V, GND = 0V
All voltages are measured with respect to GND.
Unless otherwise specified, all currents are positive when
flowing into the IC.
Minimum/Maximum characteristics conditions:
T J = -40° to +125°C, V DD = 10V to 15V, GND = 0V
