Function:
Filter connection for internal bias voltage, typically 50% of VREF. Capacitors must be connected from
CMOUT to analog ground, as shown in Figure 4. CMOUT has a typical source impedence of 25 k and
any current drawn from this pin will alter device performance
Ground reference for the internal sampling circuits. Must be connected to analog ground.
Positive reference for internal sampling circuits. External capacitors are required from FILT+ to analog
ground, as shown in Figure 4. The recommended values will typically provide 60 dB of PSRR at 1 kHz
and 40 dB of PSRR at 120 Hz. FILT+ is not intended to supply external current.
Analog voltage reference. Typically 5VDC.
The Mode Select pins determine the operational mode of the device as detailed in Tables 7-10. The op-
tions include;
Selection of the Digital Interface Format which determines the required relationship between the
Left/Right clock, serial clock and serial data as detailed in Figures 20-23
Selection of the standard 15 s/50 s digital de-emphasis filter response, Figure 28, which requires re-
configuration of the digital filter to maintain the proper filter response for 32, 44.1 or 48 kHz sample rates.
Selection of the appropriate clocking mode to match the input sample rates.
In I
device will enter the SPI mode at anytime a high to low transition is detected on this pin. Once the device
has entered the SPI mode, it will remain until either the part is reset or undergoes a power-down cycle.

C mode, AD0 is a chip address bit. CS is used to enable the control port interface in SPI mode. The
