CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8300 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
WARNING!

PIN DESCRIPTIONS
Pin #
Name
Function
1VDD
Positive power supply input. Specified range
of operation +2.7 V to +5.5 V.
2
CS
Chip Select, active low input. Disables shift
register loading when high. Does not affect
LD operation.
3
CLK
Clock input, positive edge clocks data into
shift register.
4
SDI
Serial Data Input, input data loads directly
into the shift register, MSB first.
5
LD
Load DAC register strobes, active low.
Transfers shift register data to DAC register.
See Truth Table I for operation. Asynchro-
nous active low input.
6
CLR
Resets DAC register to zero condition.
Asynchronous active low input.
7
GND
Analog and Digital Ground.
8VOUT
DAC voltage output, 2.0475 V full scale
with 0.5 mV per bit. An internal tempera-
ture stabilized reference maintains a fixed
full-scale voltage independent of time, tem-
perature and power supply variations.
