12-Bit, 300ksps ADCs

with FIFO and Internal Reference

Electrical Characteristics (continued)

(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.)
