(2) All performance measurements done with 20kHz low-pass filter and, where noted, A-weighted filter. Failure to use such a filter may result in higher THD+N and lower SNR and dynamic range readings than shown in the Electrical Characteristics. The low-pass filter removes out-of-band noise, which, although not audible, may affect dynamic specification values 8 Submit Documentation Feedback Copyright © 2010–2014, Texas Instruments Incorporated Product Folder Links: TLV320AIC3206 |
