Typical Operating Characteristics
(AVDD = DVDD = +5V, external reference = +4.096V, CREF = 10F, CREFADJ = 0.1F, VREFADJ = AVDD, CLOAD = 20pF, TA = TMIN to
TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Typical Application Circuit)

9R/C
Read/Convert Input. Power up and place the MAX1157/MAX1159/MAX1175 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 0.1F 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.
