3. CHARACTERISTICS AND SPECIFICATIONS

3.1

Electrical Characteristics

Typical characteristics conditions:

TA =25°C, VDD = 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:

TJ = -40° to +125°C, VDD = 10V to 15V, GND = 0V
