ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS—MAX7426
(VDD = +5V, filter output measured at OUT, 10k
|| 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.......................................................1s
Continuous Power Dissipation (TA = +70°C)
8-Pin µMAX (derate 4.1mW/°C above +70°C) .............330mW
8-Pin PDIP (derate 6.90mW/°C above +70°C).............552mW
Operating Temperature Ranges
MAX742 _C_A ....................................................0°C to +70°C
MAX742 _E_A .................................................-40°C to +85°C
Storage Temperature Range .............................-65°C to +160°C
Lead Temperature (soldering, 10s) .................................+300°C
COSC = 1000pF (Note 3)
VOS = 0 to VDD
SHDN = GND, VCOM = 0 to VDD
(Note 1)
TA = +25°C
Input, COM externally driven
