Reference voltage for analog-to-digital conversion (internal or external reference). Reference input for
external reference. Bypass internal reference with 1μF capacitor to GND.
REF
5
Active-Low Chip Select. Data is not clocked into DIN unless
CS
is low. When
CS
is high, DOUT is high
impedance.
Serial Data Input. Data is clocked in at the rising edge of SCLK.
CS
7
Serial Data Output. Data is clocked out on the falling edge of SCLK. High impedance when
CS
is high.
Serial Clock Input. Clocks data in and out of serial interface. In external clock mode, SCLK also sets the
conversion speed.
DOUT
9
DIN
8
Common reference for analog inputs. Sets zero-code voltage in single-ended mode. Must be stable to
±0.5LSB during conversion.
