Pin Description
PIN
NAME
FUNCTION
1
REF
ADC Reference Input. Connect a 2.048V voltage source to REF. Bypass REF to AGND with 4.7F capacitor.
2AVDD
Analog Supply. Connect to pin 4.
3
AGND
Analog Ground. This is the primary analog ground (star ground).
4AVDD
Analog Supply, 3.3V
±5%. Bypass AVDD to AGND (pin 3) with a 0.1F capacitor.
5
DGND
Digital Ground
6
SHDN
Shutdown Control Input. Drive
SHDN low to put the ADC in shutdown mode.
7
P2
User-Programmable Output 2
8
P1
User-Programmable Output 1
9
P0
User-Programmable Output 0
10
SSTRB
Serial Strobe Output. In internal clock mode, SSTRB goes low when the ADC begins a conversion and goes
high when the conversion is finished. In external clock mode, SSTRB pulses high for one clock period before
the MSB decision. It is high impedance when
CS is high in external clock mode.
11
DOUT
Serial Data Output. MSB first, straight binary format for unipolar input, two’s complement for bipolar input.
Each bit is clocked out of DOUT at the falling edge of SCLK.
12
RST
Reset Input. Drive
RST low to put the device in the power-on default mode. See the Power-On Reset section.
13
SCLK
Serial Data Clock Input. Serial data on DIN is loaded on the rising edge of SCLK, and serial data is updated
on DOUT on the falling edge of SCLK. In external clock mode SCLK sets the conversion speed.
14
DGND
Digital Ground. Connect to pin 5.
15
DVDD
Digital Supply, 3.3V
±5%. Bypass DVDD to DGND (pin 14) with a 0.1F capacitor.
16
DIN
Serial Data Input. Serial data on DIN is latched on the rising edge of SCLK.
17
CS
Chip Select Input. Drive
CS low to enable the serial interface. When CS is high DOUT is high impedance. In
external clock mode SSTRB is high impedance when
CS is high.
18
CREF
Reference Buffer Bypass. Bypass CREF to AGND (pin 3) with 1F.
19
AGND
Analog Ground. Connect to pin 3.
20
AIN
Analog Input
