Noise shaping filter DAC
Product specification
TDA1386T
FUNCTIONAL DESCRIPTION
The TDA1386T CMOS DAC incorporates an up-sampling
filter, a noise shaper, continuous calibrated current
sources and operational amplifiers.
System clock and data input format
The TDA1386T accommodates slave mode only
consequently, in all applications, the system devices must
provide the 256fs system clock.
The TDA1386T supports the following data input modes:
I2S-bus with data word length of up to 20 bits.
LSB fixed serial format with data word length of 16, 18
or 20 bits. As this format idles on the MSB it is necessary
to know how many bits are being transmitted.
The data input formats are illustrated in Fig.7. Left and
right data-channel words are time multiplexed.

Device operation
When the APPL pin is held HIGH and APP3 is held LOW,
pins APP0, APP1 and APP2 form a microcontroller
interface. When the APPL pin is held LOW, pins APP0,
APP1, APP2 and APP3 form pseudo-static application
pins (TDA1305T pin compatible).
In the pseudo-static application mode the TDA1386T is pin
compatible with the TDA1305T slave mode. The
correspondence between TDA1386T pin number,
TDA1386T pin name, TDA1305T pin name and a
description of the effects is given in Table 2.
PSEUDO-STATIC APPLICATION MODE (APPL = LOGIC 0)
In this mode, the device operation is controlled by
pseudo-static application pins (APP0: attenuation mode
control; APP1: double-speed mode control; APP2: mute
mode control and APP3: de-emphasis mode control).
