Description
1
SYNC
Active Low Input. This is the frame synchronization signal for the serial interface. While SYNC is low,
data is transferred in on the falling edge of SCLK.
2
SCLK
Serial Clock Input. Data is clocked into the input shift register on the falling edge of SCLK. This
operates at clock speeds up to 30 MHz.
3
SDIN
Serial Data Input. Data must be valid on the falling edge of SCLK.
4
SDO
Serial Data Output. Used to clock data from the serial register in daisy-chain or readback mode.
5
CLR
Negative Edge Triggered Input. Asserting this pin sets the data register to 0x0000. There is an internal
pull-up device on this logic input. Therefore, this pin can be left floating and defaults to a Logic 1
condition.
6
LDAC
Load DAC. Logic input. This is used to update the data register and consequently the analog outputs.
When tied permanently low, the addressed data register is updated on the rising edge of SYNC. If
LDAC is held high during the write cycle, the DAC input shift register is updated but the output
update is held off until the falling edge of LDAC. In this mode, all analog outputs can be updated
simultaneously on the falling edge of LDAC. The LDAC pin must not be left unconnected.
7, 8
D0, D1
Digital I/O Port. The user can set up these pins as inputs or outputs that are configurable and readable
over the serial interface. When configured as inputs, these pins have weak internal pull-ups to DVCC.
When programmed as outputs, D0 and D1 are referenced by DVCC and DGND.
9
RSTOUT
Reset Logic Output. This is the output from the on-chip voltage monitor used in the reset circuit. If
desired, it can be used to control other system components.
10
RSTIN
Reset Logic Input. This input allows external access to the internal reset logic. Applying a Logic 0 to
this input clamps the DAC outputs to 0 V. In normal operation, RSTIN should be tied to Logic 1.
Register values remain unchanged.
11
DGND
Digital Ground.
12
DVCC
Digital Supply. Voltage ranges from 2.7 V to 5.25 V.
13, 31
AVDD
Positive Analog Supply. Voltage ranges from 11.4 V to 16.5 V.
14
PGND
Ground Reference Point for Analog Circuitry.
15, 30
AVSS
Negative Analog Supply. Voltage ranges from 11.4 V to 16.5 V.
16
ISCC
Resistor Connection for Pin Programmable Short-Circuit Current. This pin is used in association with an
optional external resistor to AGND to program the short-circuit current of the output amplifiers. Refer
to the Design Features section for further details.
17
AGNDD
Ground Reference Pin for DAC D Output Amplifier.
18
VOUTD
Analog Output Voltage of DAC D. This pin is a buffered output with a nominal full-scale output range
of ±10 V. The output amplifier is capable of directly driving a 10 kΩ, 200 pF load.
19
VOUTC
Analog Output Voltage of DAC C. This pin is a buffered output with a nominal full-scale output range
of ±10 V. The output amplifier is capable of directly driving a 10 kΩ, 200 pF load.
20
AGNDC
Ground Reference Pin for DAC C Output Amplifier.
