Rev.1.22 Mar 30, 2007 Page 25 of 53

REJ03B0088-0122

NOTES:

1. Referenced to V

CC=AVCC=VREF=3.3 to 5.5V, VSS=AVSS=0V at Topr = −20 to 85°C / −40 to 85°C unless otherwise specified.

2. φAD frequency must be 10 MHz or less.

3. When sample & hold function is disabled, φAD frequency must be 250 kHz or more, in addition to the limitation in Note 2.

4. When sample & hold function is enabled, φAD frequency must be 1MHz or more, in addition to the limitation in Note 2.
