Specifications subject to change without notice.
Lower sampling rates than those given by this formula are possible, but the jitter rejection will decrease.
Refer to the Typical Performance Characteristics section for DNR and THD + N numbers over a wide range of input and output sample rates.
For any other ratio, minimum THD + N will be better than –115 dB. Please refer to detailed performance plots.
