Description
The CS4382A is a complete 8-channel digi tal-to-analog
system. This D/A system includes digital de-emphasis,
1 dB step size volume control, ATAPI channel mixing,
selectable fast and slow digital interpolation filters followed by an oversampled, multi-bit delta-sigma
modulator which includes mismatch shaping technology that eliminates distortion due to capacitor mismatch.
Following this stage is a multi-element switched capacitor stage and low-pass filter with differential analog
outputs.
The CS4382A also has a proprietary DSD processor
which allows for 50 kHz on-chip filtering without an intermediate decimation stage. The CS4382A is available
in a 48-pin LQFP package in both Commercial (-40°C to
+85°C) and Automotive grades (-40°C to +105°C). The
CDB4382A Customer Demonstration board is also
available for device evaluation and implementation suggestions. Please see “Ordering Information” on page 48
for complete details.
The CS4382A accepts PCM data at sample rates from
4 kHz to 216 kHz, DSD audio data, and delivers excellent sound quality. These featu res are ideal for multichannel audio systems including SACD players, A/V receivers, digital TV’s, mixing consoles, effects
processors, sound cards, and automotive audio
systems.

Control Port Power (Input) - Determines the required signal level for the Control Port. Refer to the
Recommended Operating Conditions for appropriate voltages.
Reset (Input) - The device enters a low power mode and all internal registers are reset to their default
19
settings when low.
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits.
Requires the capacitive decoupling to analog ground, as shown in the Typical Connection Diagram.
Quiescent Voltage (Output) - Filter connection for internal quiescent voltage. VQ must be capacitively
coupled to analog ground, as shown in the Typical Connection Diagram. The nominal voltage level is
specified in the Analog Characteristics and Specifications section. VQ presents an appreciable source
impedance and any current drawn from this pin will alter device performance. However, VQ can be
used to bias the analog circuitry assuming there is no AC signal component and the DC current is less
than the maximum specified in the Analog Characteristics and Specifications section.
Mute Control (Output) - These pins are intended to be used as a control for external mute circuits to
41
prevent the clicks and pops that can occur in any single supply system. The use of external mute cir-
22
cuits are not mandatory but may be desired for designs requiring the absolute minimum in extraneous
clicks and pops.

Differential Analog Output (Output) - The full-scale differential analog output level is specified in the
Analog Characteristics specification table.
Serial Audio Interface Power (Input) - Determines the required signal level for the serial audio interface. Refer to the Recommended Operating Conditions for appropriate voltages.
Test - These pins need to be tied to analog ground.
Serial Control Port Clock (Input) - Serial clock for the serial Control Port. Requires an external pull-up
resistor to the logic interface voltage in I²C
Serial Control Data (Input/Output) - SDA is a data I/O line in I²C Mode and requires an external pull-up
resistor to the logic interface voltage, as shown in the Typical Connection Diagram. CDIN is the input
data line for the Control Port interface in SPI
Address Bit 0 (I²C) / Control Port Chip Select (SPI) (Input) - AD0 is a chip address pin in I²C Mode;
CS is the chip select signal for SPI format.

Notes:
8. Slow roll-off interpolation filter is only available in Software Mode.
9. Response is clock-dependent and will scale with Fs.
10. For Single-Speed Mode, the Measurement Bandwidth is from stopband to 3 Fs.
For Double-Speed Mode, the Measurement Bandwidth is from stopband to 3 Fs.
For Quad-Speed Mode, the Measurement Bandwidth is from stopband to 1.34 Fs.
11. De-emphasis is available only in Single-Speed Mode; only 44.1 kHz De-emphasis is available in Hardware Mode.
12. Amplitude vs. Frequency plots of this data are available in Section 7. “Filter Plots” on page 42.
