MAX522

Dual, 8-Bit, Voltage-Output

Serial DAC in 8-Pin SO Package

_______________________________________________________________________________________

ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VDD = +2.7V to +5.5V, REF = VDD, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

Note 1: The outputs may be shorted to VDD or GND if the package power dissipation is not exceeded. Typical short-circuit current to

GND is 50mA.

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 to GND ................................................................ -0.3V, +6V

Digital Inputs and Outputs to GND............... -0.3V, (VDD + 0.3V)

REF ................................................................-0.3V, (VDD + 0.3V)

OUTA, OUTB (Note 1)............................................................VDD

Continuous Power Dissipation (TA = +70°C)

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

SO (derate 5.88mW/°C above +70°C) ...........................471mW

Operating Temperature Ranges

MAX522C_ A.......................................................0°C to +70°C

MAX522E_ A....................................................-40°C to +85°C

Storage Temperature Range .............................-65°C to +165°C

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