... 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 AD7314 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 ...

... SCLK. Only the third bit in the data stream provides a user-controlled function. This third bit is the power- down bit which, when set puts the AD7314 into shutdown mode. The first two bits of the data stream are don’t cares while all other bits in the data stream other than the power-down bit should ensure correct operation of the AD7314 ...

... SUPPLY DECOUPLING The AD7314 should at least be decoupled with a 0.1 mF ceramic capacitor between V and GND. This is particularly important DD if the AD7314 is mounted remote from the power supply. TYPICAL TEMPERATURE ERROR GRAPHS Figure 6 shows a typical temperature error plot for one device with V at 2.65 V. ...
