double speed
Double-speed mode is used to support sampling rates of 88.2 kHz and 96 kHz. In order to put the TAS5001 in
double-speed mode with the device in normal operating conditions, the RESET pin must be held low while
switching the DBSPD pin high. After the RESET pin is brought high again, a reset sequence takes place. If the
change is at power up, a power-up sequence is originated.
de-emphasis filter
For audio sources that have been preemphasized, a precision 50-
s/15-s de-emphasis filter is provided to
support the sampling rates of 44.1 kHz and 48 kHz. Pins DEM_SEL and DEM_EN select the de-emphasis
functions. See Figure 6 for a graph showing the de-emphasis filtering characteristics. See Table 3 for
de-emphasis selection.
