DESCRIPTION
I/O
I
I _{Bipolar analog inputs. These pins are typically used to monitor the DAC group-C outputs. The}
I ^{input range of these channels is –12.5 to 12.5 V.}
I
I
I _{Bipolar analog inputs. These pins are typically used to monitor the DAC group-D outputs. The}
I ^{input range of these channels is –12.5 to 12.5 V.}
I
I
I _{Bipolar analog inputs. These pins are typically used to monitor the DAC group-B outputs. The}
I ^{input range of these channels is –12.5 to 12.5 V.}
I
I
I _{Bipolar analog inputs. These pins are typically used to monitor the DAC group-A outputs. The}
I ^{input range of these channels is –12.5 to 12.5 V.}
I
I Analog ground. These pins are the ground reference point for all analog circuitry on the device.
I
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
I than ±0.3 V.
I
Positive analog power for DAC groups A and B. The AV_{CC_AB} and AV_{CC_CD} pins must be
connected to the same potential (AV_CC).
I
Positive analog power for DAC groups C and D. The AV_{CC_AB} and AV_{CC_CD} pins must be
connected to the same potential (AV_CC).
I Analog supply voltage (4.5 V to 5.5 V). This pin must have the same value as the DV_DD pin.
Lowest potential in the system. This pin is typically tied to a negative supply voltage but if all
I
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.
Negative analog supply for DAC group B. This pin sets the power-on-reset and clamp voltage
I values for the DAC group B. This pin is typically tied to the AV_EE pin for the negative output
ranges or AGND for the positive output ranges.
Negative analog supply for DAC group C. This pin sets the power-on-reset and clamp voltage
I values for the DAC group C. This pin is typically tied to the AV_EE pin for the negative output
ranges or AGND for the positive output ranges.
Negative analog supply for DAC group D. This pin sets the power-on-reset and clamp voltage
I values for the DAC group D. This pin is typically tied to the AV_EE pin for the negative output
ranges or AGND for the positive output ranges.
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.
O
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
O _{voltage range as well.}

O
