CS4226

DS188F1
FUNCTIONAL DESCRIPTION
Overview
The CS4226 has 2 channels of 20-bit analog-to-
digital conversion and 6 channels of 20-bit digital-
to-analog conversion. A mono 20-bit ADC is also
provided. All ADCs and DACs are delta-sigma
converters. The stereo ADC inputs have adjustable
input gain, while the DAC outputs have adjustable
output attenuation. The device also contains an
S/PDIF receiver capable of receiving compressed
AC-3/MPEG or uncompressed digital audio data.
Digital audio data for the DACs and from the
ADCs is communicated over separate serial ports.
This allows concurrent writing to and reading from
the device. The CS4226 functions are controlled
via a serial microcontroller interface. Figure 1
shows the recommended connection diagram for
the CS4226.
Analog Inputs
Line Level Inputs
AIN1R, AIN1L, AIN2R, AIN2L, AIN3R, AIN3L
and AINAUX are the line level input pins (See Fig-
ure 1). These pins are internally biased to the
CMOUT voltage. A 10
µF DC blocking capacitor
placed in series with the input pins allows signals
centered around 0 V to be input to the CS4226. Fig-
ure 2 shows an optional dual op amp buffer which
combines level shifting with a gain of 0.5 to atten-
uate the standard line level of 2 Vrms to 1 Vrms.
The CMOUT reference level is used to bias the op-
amps to approximately one half the supply voltage.
With this input circuit, the 10
µF DC blocking caps
in Figure 1 may be omitted. Any remaining DC off-
set will be removed by the internal high-pass fil-
ters.
Selection of stereo the input pair (AIN1L/R,
AIN2L/R or AIN3L/R) for the 20-bit ADC’s is ac-
complished by setting the AIS1/0 bits (ADC analog
input mux control), which are accessible in the
ADC Control Byte. On-chip anti-aliasing filters
follow the input mux providing anti-aliasing for all
input channels.
The analog inputs may also be configured as differ-
ential inputs. This is enabled by setting bits
AIS1/0=3. In the differential configuration, the left
channel inputs reside on pins 10 and 11, and the
right channel inputs reside on pins 12 and 13 as de-
scribed in Table 1 below. In differential mode, the
full scale input level is 2 Vrms.
The analog signal is input to the mono ADC via the
AINAUX pin.
Independent Muting of both the stereo ADC’s and
the mono ADC is possible through the ADC Con-
trol Byte with the MUTR, MUTL and MUTM bits.
