LDAC
This active low-control input transfers the contents of the input registers to their respective DAC registers.
Pulsing this pin low allows any or all DAC registers to be updated if the input registers have new data.
This allows simultaneous update of all DAC outputs. Alternatively, this pin can be tied permanently low.
Active Low-Control Input. This is the frame synchronization signal for the input data. When
SYNC
goes
low, it powers on the SCLK and DIN buffers and enables the input shift register. Data is transferred in
on the falling edges of the following 16 clocks. If
SYNC
is taken high before the 16th falling edge, the
rising edge of
SYNC
acts as an interrupt and the write sequence is ignored by the device.
Power Supply Input. These parts can be operated from 2.5 V to 5.5 V, and the supply should be
decoupled with a 10
μ
F capacitor in parallel with a 0.1
μ
F capacitor to GND.
Buffered Analog Output Voltage from DAC A. The output amplifier has rail-to-rail operation.
Buffered Analog Output Voltage from DAC B. The output amplifier has rail-to-rail operation.
Buffered Analog Output Voltage from DAC C. The output amplifier has rail-to-rail operation.
Buffered Analog Output Voltage from DAC D. The output amplifier has rail-to-rail operation.
Reference Input Pin for DACs A, B, C, and D. It may be configured as a buffered, unbuffered, or V
DD
input to the four DACs, depending on the state of the BUF and V
DD
control bits. It has an input range
from 0.25 V to V
DD
in unbuffered mode and from 1 V to V
DD
in buffered mode.
Reference Input Pin for DACs E, F, G, and H. It may be configured as a buffered, unbuffered, or V
DD
input to the four DACs, depending on the state of the BUF and V
DD
control bits. It has an input range
from 0.25 V to V
DD
in unbuffered mode and from 1 V to V
DD
in buffered mode.
Buffered Analog Output Voltage from DAC E. The output amplifier has rail-to-rail operation.
Buffered Analog Output Voltage from DAC F. The output amplifier has rail-to-rail operation.
Buffered Analog Output Voltage from DAC G. The output amplifier has rail-to-rail operation.
Buffered Analog Output Voltage from DAC H. The output amplifier has rail-to-rail operation.
Ground Reference Point for All Circuitry on the Part.
Serial Data Input. This device has a 16-bit shift register. Data is clocked into the register on the falling
edge of the serial clock input. The DIN input buffer is powered down after each write cycle.
Serial Clock Input. Data is clocked into the input shift register on the falling edge of the serial clock
input. Data can be transferred at rates up to 30 MHz. The SCLK input buffer is powered down after
each write cycle.
