4 / 8 page REV. A AD8300 –4– 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!

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.
