DESCRIPTION
NAME
NO.
I/O
ADC_0
47
I
Bipolar analog inputs. These pins are typically used to monitor the DAC group-C outputs. The
input range of these channels is –12.5 to 12.5 V.
ADC_1
46
I
ADC_2
45
I
ADC_3
44
I
ADC_4
43
I
Bipolar analog inputs. These pins are typically used to monitor the DAC group-D outputs. The
input range of these channels is –12.5 to 12.5 V.
ADC_5
42
I
ADC_6
41
I
ADC_7
40
I
ADC_8
34
I
Bipolar analog inputs. These pins are typically used to monitor the DAC group-B outputs. The
input range of these channels is –12.5 to 12.5 V.
ADC_9

I
ADC_10
32
I
ADC_11
31
I
ADC_12
30
I
Bipolar analog inputs. These pins are typically used to monitor the DAC group-A outputs. The
input range of these channels is –12.5 to 12.5 V.
ADC_13
29
I
ADC_14

I
ADC_15
27
I
AGND1
21
I
Analog ground. These pins are the ground reference point for all analog circuitry on the device.
Connect the AGND1, AGND2, and AGND3 pins to the same potential (AGND). Ideally, the
analog and digital grounds should be at the same potential (GND) and must not differ by more
than ±0.3 V.
AGND2
48
I
AGND3
56
I
AVCC_AB
20
I
Positive analog power for DAC groups A and B. The AVCC_AB and AVCC_CD pins must be
connected to the same potential (AVCC).
AVCC_CD
57
I
Positive analog power for DAC groups C and D. The AVCC_AB and AVCC_CD pins must be
connected to the same potential (AVCC).
AVDD
50
I
Analog supply voltage (4.7 V to 5.5 V). This pin must have the same value as the DVDD pin.
AVEE
17
I
Lowest potential in the system. This pin is typically tied to a negative supply voltage but if all
DACs are set in a positive output range, this pin can be connected to the analog ground. This
pin also acts as the negative analog supply for DAC group A. This pin sets the power-on-reset
and clamp voltage values for the DAC group A.
AVSSB
24
I
Negative analog supply for DAC group B. This pin sets the power-on-reset and clamp voltage
values for the DAC group B. This pin is typically tied to the AVEE pin for the negative output
ranges or AGND for the positive output ranges.
AVSSC
53
I
Negative analog supply for DAC group C. This pin sets the power-on-reset and clamp voltage
values for the DAC group C. This pin is typically tied to the AVEE pin for the negative output
ranges or AGND for the positive output ranges.
AVSSD
60
I
Negative analog supply for DAC group D. This pin sets the power-on-reset and clamp voltage
values for the DAC group D. This pin is typically tied to the AVEE pin for the negative output
ranges or AGND for the positive output ranges.
CS
6
I
Active-low serial-data enable. This input is the frame-synchronization signal for the serial data.
When this signal goes low, it enables the serial interface input shift register.
DAC_A0
15
O
DAC group A. These DAC channels share the same range and clamp voltage. If any of the
other DAC groups is in a negative voltage range, DAC group A should be in a negative
voltage range as well.
DAC_A1
16
O
DAC_A2
18
O
DAC_A3
19
O
DAC_B4
22
O
DAC group B. These DAC channels share the same range and clamp voltage.
DAC_B5

DAC_B6
