7 / 15 page REV. PrC PRELIMINARY TECHNICAL DATA –7– AD7451/AD7441 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 AD7451/AD7441 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.

This is a stress rating only and functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2Transient currents of up to 100 mA will not cause SCR latch up.

This board is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designators. To order a complete Evaluation Kit, you will need to order the ADC evaluation board i.e. TBD, the EVAL-CONTROL BRD2 and a 12V AC transformer. See the TBD technote for more information. 4RT = SOT-23; RM = µSOIC Figure 3. Load Circuit for Digital Output Timing Specifications IOL 1.6mA IOH 200µA +1.6V CL 50pF TO OUTPUT PIN |
