AGND Analog Ground. Connect all return paths for analog signals to AGND.
2, 3, 10,
11, 14, 15,
20, 42, 47
AV
DD
Analog Supply Voltage. For optimum performance, bypass to the closest AGND with a parallel
combination of a 0.1µF and a 1nF capacitor. Connect a single 10µF and 1µF capacitor combination
between A
VDD
and A
GND
.
6 INP Positive Analog Signal Input
7 INN Negative Analog Signal Input
17 CLK Clock Frequency Input. Clock frequency input ranges from 100kHz to 60MHz.
18 CLK
Complementary Clock Frequency Input. This input is used for differential clock inputs. If the ADC is
driven with a single-ended clock, bypass CLK with a 0.1µF capacitor to AGND.
21, 31, 32
DV
DD
Digital Supply Voltage. For optimum performance, bypass to the closest DGND with a parallel
combination of a 0.1µF and a 1nF capacitor. Connect a single 10µF and 1µF capacitor combination
between D
VDD
and D
GND
.
22, 29, 30
DGND Digital Ground
23–28 D0–D5 Digital Data Outputs. Data bits D0 through D5, where D0 represents the LSB.
33–38 D6–D11 Digital Data Outputs. D6 through D11, where D11 represents the MSB.
39 OE
Output Enable Input. A logic “1” on OE places the outputs D0–D11 into a high-impedance state. A
logic “0” allows for the data bits to be read from the outputs.
40 PD Shutdown Input. A logic “1” on PD places the ADC into shutdown mode.
43 REFIN
External Reference Input. Bypass to AGND with a capacitor combination of 0.22µF in parallel with
1nF. REFIN can be biased externally to adjust reference levels and calibrate full-scale errors. To
disable the internal reference, connect REFIN to AGND.
