ELECTRICAL CHARACTERISTICS TEST CONDITION, unless otherwise specified: VCC = 5V;

VSS = -5V; VBAT = -48V; AGND = BGND; Direct Polarity; TA = 25°C.

Note: Testing of all parameters is performed at 25°C. Characterization as well as the design rules used

allow correlation of tested performances at other temperatures. All parameters listed here are

met in the range 0°C to +70°C. Functionality between -40°C and 85°C is verified.
