NAME
DESCRIPTION
1VDD
Power-Supply Input, +2.7V to +5.5V
2VREF
Reference Voltage Input
3VFB
Feedback connection for the output amplifier.
4VOUT
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 synchronization 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 DAC8501.
6
SCLK
Serial Clock Input. Data can be transferred at rates
up to 30MHz.
7DIN
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.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
