Product specification
Low power audio DAC
UDA1334BT
8.6
Feature settings
The features of the UDA1334BT can be set by control
pins SFOR1, SFOR0, MUTE, DEEM and PCS.
8.6.1

IGITAL INTERFACE FORMAT SELECT
The digital audio interface formats (see Fig.5) can be
selected via the pins SFOR1 and SFOR0 as shown in
Table 4.

EMPHASIS CONTROL
De-emphasis can be switched on for f
s
= 44.1 kHz by
setting pin DEEM at HIGH level. The function description
of pin DEEM is given in Table 6.

De-emphasis control
Remark:
the de-emphasis function in only supported in
the normal operating mode, not in the low sampling
frequency mode.

P
OWER CONTROL AND SAMPLING FREQUENCY
SELECT
Pin PCS is a 3-level pin and is used to set the mode of the
UDA1334BT. The definition is given in Table 7.
Table 7
PCS function definition
The low sampling frequency mode is required to have a
higher oversampling rate in the noise shaper in order to
improve the signal-to-noise ratio. In this mode the
