PIN DESCRIPTION
PIN NAME DESCRIPTION
1
V_DD
Power-Supply Input, +2.7V to +5.5V.
2
V_REF
Reference Voltage Input
3
V_FB
Feedback connection for the output amplifier.
4
V_OUT
Analog output voltage from DAC. The output ampli-
fier has rail-to-rail operation.
5
SYNC
Level-triggered control input (active LOW). This is
the frame sychronization signal for the input data.
When SYNC goes LOW, it enables the input shift
register and data is transferred in on the falling
edges of the following clocks. The DAC is updated
following the 24th clock cycle unless SYNC is taken
HIGH before this edge, in which case the rising
edge of SYNC acts as an interrupt and the write
sequence is ignored by the DAC8531.
6
SCLK
Serial Clock Input. Data can be transferred at rates
up to 30MHz.
7
D_IN
Serial Data Input. Data is clocked into the 24-bit
input shift register on the falling edge of the serial
clock input.
8
GND
Ground reference point for all circuitry on the part.
