NOTES:
1. The analog power supplies for AD converters (Pins 17 and 44) must be turned on simultaneously with or before other power supplies.
turning on these power supplies after any other power supply may cause the device to fall into latch-up condition. This precaution, how-
ever, does not apply when turning off the power supplies.
2. Although the device can operate with low f
S
frequencies such as f
S
= 8kHz or 16kHz, its analog characteristics deteriorate to extent. When
used at only these low frequencies, the CXD2570Q is recommended that is pin-compatible with the CXD2555Q.
CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
