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.

Electrical Characteristics

(VDD = +2.7V to +3.6V (MAX11627/MAX11629/MAX11633); VDD = +4.75V to +5.25V (MAX11626/MAX11628/MAX11632), fSAMPLE

= 300kHz, fSCLK = 4.8MHz external clock (50% duty cycle), VREF = 2.5V (MAX11627//MAX11629/MAX11633); VREF = 4.096V

(MAX11626/MAX11628/MAX11632), TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
