AD7453

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

AD7453 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.

NOTES

1Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating only; 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.

NOTES

1Linearity error here refers to integral nonlinearity error.

2This can be used as a standalone evaluation board or in conjunction with the evaluation board controller for evaluation/demonstration purposes.

3The evaluation board controller is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designa-

tors. To order a complete Evaluation Kit, you will need to order the ADC evaluation board, i.e., EVAL-AD7453CB, the EVAL-CONTROL BRD2, and a 12 V ac

transformer. See the AD7453 application note for more information.
