ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VDD = +2.5V to +5.5V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

VDD, SCLK, DIN, CS, LDAC, OUT_ to GND ...............-0.3V to 6V

REF to GND ................................................-0.3V to (VDD + 0.3V)

Maximum Current (any pin) .............................................±50mA

Continuous Power Dissipation (TA = +70°C)

Plastic DIP (derate 9.09mW/°C above +70°C) .............727mW

µMAX (derate 4.10mW/°C above +70°C) .....................330mW

Operating Temperature Ranges

MAX5_ _AC_ A.....................................................0°C to +70°C

MAX5_ _AE_ A ..................................................-40°C to +85°C

Storage Temperature Range .............................-65°C to +150°C

Lead Temperature (soldering, 10sec) .............................+300°C
