ANALOG FRONT END
The PCM1850A/1851A has a built-in analog front-end circuit, which is shown in the block diagram of
Figure 22
.
Selection of the multiplexer input and PGA gain is controlled by mode control via the serial port as shown in
Table 2
and
Table 3
. The change of the input selection and the gain selection is performed immediately after the
serial control packet for the change is sent. A popping noise or other unexpected transient response could be
generated in the audio signal during channel and gain change. Because the PCM1850A/1851A has no
zero-cross detection and no other buffering capability for channel and gain change, appropriate data handling in
the digital domain is recommended to control transients.

SLES173–MARCH 2006
The PCM1850A/1851A analog front end permits only ac input via an input capacitor; dc input is prohibited. A
signal source resistance of less than 1 k
is recommended for the V
IN
xx pins.
All unselected channel inputs are terminated V

S (= 0.5 V
CC
) using a resistor, typically 57 k
.
The PCM1850A/1851A employs MOUTL/R pins (pins 12 and 11) to monitor the multiplexer output. The load on
these pins must be ac-coupled and not less than 10 k
. The full-scale output level is typically 0.6 V
CC
.
