The UTC
UA2311
accepts serial input data format of 16-bits word length. Both left and right data words are time
multiplexed. The last 16 bits word before “WS” changes is recognized as the input data.
The timing and input signal
formats are shown in Figure 1 and 2.
The most significant bit (bit 1) must always be first.
The serial input data is shifted and latched for the Right and
Left Channels.
With a HIGH level on the word select input (WS), data is placed in the left input register and with
a LOW level on the WS input, data is placed in the right input register(see Block Diagram). The data in the
input registers are simultaneously latched in the output registers which control the bit switches.
The 16 bits Right/Left Data is then converted to floating point expression whose format consists of 10 bits
mantissa and 7 step exponent. This floating point expression is then converted to analog output voltage by the
resistor-string. This signal is driven to the Right/Left Channel (V
OR
/V
OL
) by the buffer operational amplifier.
