CNVST, SCLK, DOUT to GND....................-0.3V to (VDD + 0.3V)
REF, AIN1 (AIN+), AIN2 (AIN-) to GND......-0.3V to (VDD + 0.3V)
Maximum Current into Any Pin............................................50mA
Continuous Power Dissipation (TA = +70°C)
8-Pin SOT23 (derate 9.70mW/°C above TA = +70°C) ...696mW
Operating Temperature Range ...........................-40°C to +85°C
Storage Temperature Range .............................-60°C to +150°C
Lead Temperature (soldering, 10s) .................................+300°C
Stresses beyond those listed under âAbsolute Maximum Ratingsâ 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.
ELECTRICAL CHARACTERISTICS
(VDD = +2.7V to +3.6V, VREF = +2.5V for MAX1287/MAX1289, or VDD = +4.75V to +5.25V, VREF = +4.096V for MAX1286/MAX1288,
0.1µF capacitor at REF, fSCLK = 8MHz (50% duty cycle), AIN- = GND for MAX1288/MAX1289. TA = TMIN to TMAX, unless otherwise
noted. Typical values at TA = +25°C.)
