Power up and place the MAX1179/MAX1187/MAX1189 in acquisition mode by holding R/C low during the first falling edge of CS. During the second falling edge of CS, the level on R/C determines whether the reference and reference buffer power down or remain on after conversion. Set R/C high during the second falling edge of CS to power down the reference and buffer, or set R/C low to leave the reference and buffer powered up. Set R/C high during the third falling edge of CS to put valid data on the bus. 10 EOC End of Conversion. EOC drives low when conversion is complete. 11 AVDD Analog Supply Input. Bypass with a 0.1µF capacitor to AGND. 12 AGND Analog Ground. Primary analog ground (star ground). 13 AIN Analog Input 14 AGND Analog Ground. Connect pin 14 to pin 12. Typical Operating Characteristics (continued) (AVDD = DVDD = +5V, external reference = +4.096V, CREF = 10µF, CREFADJ = 0.1µF, VREFADJ = AVDD, CLOAD = 20pF, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Typical Application Circuit) |
