FUNCTIONAL DESCRIPTION
The TDA1543 accepts input serial data formats in two's complement with any bit length. Left and right data words are
time multiplexed. The most significant bit (bit 1) must always be first. The format of data input is shown in Fig.5 and Fig.6.
This flexible input data format (I
correction circuits and audio signal processor circuits (ASP).
The high maximum input bit-rate and fast settling current facilitates application in 4
adjustable current is added to the output currents to bias output operational amplifiers (OP1; OP2) for maximum dynamic
range (see Fig.1).
With a LOW level on the word select (WS) input data is placed in the left input register and with a HIGH level on the WS
input data is placed in the right input register. The data in the input registers is simultaneously latched in the output
registers which control the bit switches.
The output current of the DAC is a sink current. The current I
