Note: We assume that the measurements for the allowable operating ranges and electrical characteristics described in this document are performed with the chip mounted in a package. Although this product is shipped in chip form, the characteristic values listed in this document are measured with this IC mounted on a Our designated package at operating ambient temperature range of -20°C to +70°C. The specifications of this product in package form or in chip forms are basically identical, however, the characteristics of the product in chip form may vary depending on the board on which the product is mounted, the bonding pressure, and the type of mold resin used. Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

Note 7-2: The conversion time refers to the period from the time an instruction for starting a conversion process till the time the conversion results register(s) are loaded with a complete digital conversion value corresponding to the analog input value. The conversion time is 2 times the normal-time conversion time when: • The first AD conversion is performed in the 12-bit AD conversion mode after a system reset. • The first AD conversion is performed after the AD conversion mode is switched from 8-bit to 12-bit conversion mode.
