NOTES:
1. The analog power supplies for AD converters (Pins 17 and 44) must be turned on simultaneously with or before other poser 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 F
S
frequencies such as F
S
= 44.1kHz or 48kHz, its analog characteristics deteriorate to extent.
When used at only these F
S
frequencies, the CXD255Q is recommended that is pin-compatible with the CXD2570Q.
