Pin Description
Common-Mode Level Positive Input. For AC applications, connect to AVDD to internally set the input
DC bias level. For DC-coupled applications, connect to AGND.
CMLP
11
Common-Mode Level Negative Input. Connect to AGND to internally set the input DC bias level for
both AC- and DC-coupled applications.
CMLN
12
Clock Input. Clock frequency range from 0.1MHz to 10MHz.
CLK
13
Active-Low Output Enable and Power-Down Input. Digital outputs become high impedance and
device enters low-power mode when pin is high.
OE/PD
14
Digital Data Output (MSB)
D9
15
Negative Reference Output. Bypass to AGND with 0.1F capacitor. REFN can accept an external
voltage when the internal reference is disabled (REFN = AGND).
REFN
5
Common-Mode Level Input. Bypass to AGND with a 0.1F capacitor. CML can accept an external
voltage when the internal reference is disabled (REFN = AGND).
CML
6
Positive Analog Signal Input
INP
9
Negative Analog Signal Input
INN
10
External Reference Input. Bypass to AGND with a 0.1F capacitor. REFIN can be biased externally
to adjust the reference level and calibrate full-scale errors. To disable the internal reference, connect
REFIN to AGND.
REFIN
4
Positive Reference Output. Bypass to AGND with a 0.1F capacitor. If the internal reference is
disabled, REFP can accept an external voltage.
REFP
3
PIN
Analog Supply Voltage Input. Bypass with a parallel combination of 2.2F, 0.1F, and 100pF capacitors
to AGND. Bypass each supply input to the closest AGND (e.g., capacitors between pins 1 and 2).
AVDD
2, 8
Analog Ground. Connect all return paths for analog signals to these pins.
AGND
