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 current are positive when
flowing into the IC.
Minimum/Maximum characteristics conditions:
T_J = -40° to +125 °C, V_DD = 10V to 15V, GND = 0V
