... V to +12.5 V when using dual supplies. The part is also specified for single supply operation using a reference of +10 V. The output amplifier is capable of developing +10 V across load. The AD7224 is fabricated in an all ion-implanted high speed 2 Linear Compatible CMOS (LC MOS) process which has been specifically developed to allow high speed digital logic circuits and precision analog circuits to be integrated on the same chip ...

... 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 AD7224 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 ...

... SHOWN FOR ALL 1's ON DAC cally possible. INTERFACE LOGIC INFORMATION Table I shows the truth table for AD7224 operation. The part contains two registers, an input register and a DAC register. CS and WR control the loading of the input register while LDAC and WR control the transfer of information from the input regis- ter to the DAC register ...

... Mismatch between R1 and R2 causes gain and offset errors; therefore, these resistors must match and track over tempera- ture. Once again, the AD7224 can be operated in single supply or from positive/negative supplies. Table III shows the digital code versus output voltage relationship for the circuit of Figure 6 with ...
