Description
Analog Sampling Inputs.
These eight pins serve as analog sampling inputs.
Common Analog Inputs
. Tie this pin to ground in single-ended mode.
Positive Supply Voltage
Reference-Buffer Output/A/DC Reference Input
. This pin serves as the reference
voltage for analog-to-digital conversions. In internal reference mode, the reference
buffer provides a +2.50V nominal output, externally adjustable at pin REFADJ. In
external reference mode, disable the internal buffer by pulling pin REFADJ to V
DD1
.
Reference-Buffer Amplifier Input
. To disable the reference-buffer amplifier, tie this
pin to V
DD1
.
Analog and Digital Ground
Serial Data Output
. Data is clocked out at the rising edge of pin SCLK. DOUT is high
impedance when CSN is high.
Serial Strobe Output
. SSTRB pulses high for one clock period before the MSB is
clocked out. SSTRB is high impedance when CSN is high.
Serial Data Input
. Data is clocked in at the rising edge of SCLK.
Active-Low Chip Select
. Data will not be clocked into pin DIN unless CSN is low.
When CSN is high, pins DOUT and SSTRB are high impedance.
Serial Clock Input
. This pin clocks data into and out of the serial interface, and is used
to set the conversion speed.
Note:
The duty cycle must be between 40 and 60%.
