Pin Description
Positive Supply Voltage
VDD2
16
Input to the Reference-Buffer Amplifier. To disable the reference-buffer amplifier, connect REFADJ to VDD1.
REFADJ
9
Serial Strobe Output. SSTRB pulses high for one clock period before the MSB decision. High impedance
when CS is high.
SSTRB
12
Serial-Data Input. Data is clocked in at SCLK’s rising edge.
DIN
13
Active-Low Chip Select. Data will not be clocked into DIN unless CS is low. When CS is high, DOUT and
SSTRB are high impedance.
CS
14
Serial-Clock Input. Clocks data in and out of serial interface and sets the conversion speed. (Duty cycle
must be 40% to 60%.)
SCLK
15
Reference-Buffer Output/ADC Reference Input. Reference voltage for analog-to-digital conversion. In
internal reference mode, the reference buffer provides a 2.500V nominal output, externally adjustable at
REFADJ. In external reference mode, disable the internal buffer by pulling REFADJ to VDD1.
REF
8
Ground
GND
10
Serial-Data Output. Data is clocked out at SCLK’s rising edge. High impedance when CS is high.
DOUT
11
Active-Low Shutdown Input. Pulling SHDN low shuts down the device, reducing supply current to 2A (typ).
SHDN
7
Ground Reference for Analog Inputs. COM sets zero-code voltage in single-ended mode. Must be
stable to ±0.5LSB.
