ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS—MAX7408/MAX7411

(VDD = +5V; filter output measured at OUT, 10kΩ || 50pF load to GND at OUT, SHDN = VDD, OS = COM, 0.1µF from COM to GND,

fCLK = 100kHz, 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 to GND ..............................................................-0.3V to +6V

IN, OUT, COM, OS, CLK, SHDN ................-0.3V to (VDD + 0.3V)

OUT Short-Circuit Duration...................................................1sec

Continuous Power Dissipation (TA = +70°C)

8-Pin DIP (derate 6.90mW/°C above +70°C) ...............552mW

8-Pin µMAX (derate 4.1mW/°C above +70°C) .............330mW

Operating Temperature Ranges

MAX74_ _C_A .....................................................0°C to +70°C
