Description
1
VDD1
P
Analog 5 V Supply. Decouple the 5 V supply with a 100 nF capacitor.
2
VDD2
P
Analog 2.5 V Supply. Decouple this pin with a 100 nF capacitor. The 2.5 V supply source should
supply this pin first and then be traced to the other VDD2 pins (Pin 7 and Pin 18).
3
CAP1
AO
Connect this pin to a 10 nF capacitor.
4
REFIN
AI/O
Prebuffer Reference Voltage. When using the internal reference, this pin outputs the band gap voltage
and is nominally at 1.2 V. It can be overdriven with an external reference voltage such as the ADR280.
In either internal or external reference mode, a 10 μF capacitor is required. If using an external 4.096 V
reference (connected to REF), this pin is a no connect and does not require any capacitor.
5, 6
EN0, EN1
DI
Enable Pins. The logic levels of these pins set the operation of the device as follows:
EN1 = 0, EN0 = 0: Illegal state.
EN1 = 0, EN0 = 1: Enable internal buffer, disable internal reference. An external 1.2 V reference
connected to the REFIN pin is required.
EN1 = 1, EN0 = 0: Disable internal reference and reference buffer. An external 4.096 V reference
connected to the REF pin is required.
EN1 = 1, EN0 = 1: Enable internal reference and reference buffer.
7
VDD2
P
Digital 2.5 V Supply. Decouple this pin with a 100 nF capacitor.
8, 9
CNV−, CNV+
DI
Convert Input. These pins act as the conversion control pin. On the rising edge of these pins, the
analog inputs are sampled and a conversion cycle is initiated. CNV+ works as a CMOS input when
CNV− is grounded; otherwise, CNV+ and CNV− are differential LVDS inputs.
10, 11
D−, D+
DO
LVDS Data Outputs. The conversion data is output serially on these pins.
12
VIO
P
Input/Output Interface Supply. Use a 2.5 V supply and decouple this pin with a 100 nF capacitor.
13
GND
P
Ground. Return path for the 100 nF capacitor connected to Pin 12.
14, 15
DCO−, DCO+
DO
LVDS Buffered Clock Outputs. When DCO+ is grounded, the self-clocked interface mode is selected.
In this mode, the 16-bit results on D± are preceded by a 2-bit header (10) to allow synchronization of
the data by the digital host with simple logic. When DCO+ is not grounded, the echoed-clock inter-
face mode is selected. In this mode, DCO± is a copy of CLK±. The data bits are output on the falling
edge of DCO+ and can be latched in the digital host on the next rising edge of DCO+.
16, 17
CLK−, CLK+
DI
LVDS Clock Inputs. This clock shifts out the conversion results on the falling edge of CLK+.
18
VDD2
P
Analog 2.5 V Supply. Decouple this pin with a 100 nF capacitor.
19, 20
VDD1
P
Analog 5 V Supply. Isolate these pins from Pin 1 with a ferrite bead and decouple them with a 100 nF
capacitor.
21
VCM
AO
Common-Mode Output. When using any reference scheme, this pin produces one-half the voltage
present on the REF pin, which can be useful for driving the common mode of the input amplifiers.
22
IN−
AI
Differential Negative Analog Input. Referenced to and must be driven 180° out of phase with IN+.
23
IN+
AI
Differential Positive Analog Input. Referenced to and must be driven 180° out of phase with IN−.
24
GND
P
Ground.
