NOTES
xxx = customer identification code.
yy = ROM identification code.
To place an order for a custom ROM-coded ADMC326 processor, please request a copy of the ADMC ROM ordering package, available from your Analog Devices
Sales representative.
Analog Devices assesses a charge for each ROM mask generated in addition to a minimum order quantity. Please consult your sales representative for details.
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 ADMC326 features proprietary ESD protection circuitry, permanent damage may
WARNING!
occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
