CS4354
5 V Stereo DAC with 2 VRMS Ground-centered Output
Features
Description
Advanced Multi-bit Delta-Sigma Modulator
101 dB A-wt Dynamic Range
-86 dB THD+N
Single-ended Ground Centered Analog
Architecture
– No DC-blocking Capacitors Required
– Integrated Inverting Charge Pump
– Filtered Line-level Outputs
– 2 VRMS Full-scale Output
Low-latency Digital Filtering
Supports Sample Rates up to 192 kHz
24-bit I²S Input
+5 V Analog Supply with Integrated Inverting
Charge Pump and Regulator for Core Logic,
and +1.8 V to +5 V Interface Power Supplies
50 mW Power Consumption
14-pin SOIC, Lead-free Assembly
The CS4354 is a complete stereo digital-to-analog sys-
tem including digital interpolation, third-order multi-bit
delta-sigma digital-to-analog conversion, digital de-em-
phasis, analog filtering, and on-chip 2 VRMS line-level
driver from a 5 V supply.
The advantages of this architecture include ideal differ-
ential linearity, no distortion mechanisms due to resistor
matching errors, no linearity drift over time and temper-
ature, high tolerance to clock jitter, and a minimal set of
external components.
The CS4354 is available in a 14-pin SOIC package in
Commercial (-40°C to +85°C) grade. The CDB4354
Customer Demonstration Board is also available for de-
vice evaluation and implementation suggestions.
Please see “Ordering Information” on page 23 for com-
plete details.
These features are ideal for cost-sensitive, 2-channel
audio systems including video game consoles, Blu-Ray
Disc® and DVD players, set-top boxes, digital TVs, and
DAB/DMB devices.

Notes: 15. Power supply current increases with increasing sample rate and increasing MCLK frequency. Typical
values are based on Fs = 48 kHz and MCLK = 12.288 MHz. Maximum values are based on highest
sample rate and highest MCLK frequency; see Switching Specifications - Serial Audio Interface. Vari-
ance between speed modes is small.
16. During normal operation, SDIN = 997 Hz sine wave at 0 dBFS with load resistance RL = 3 k.
17. Power-down is defined as all clock and data lines held static low. All digital inputs have a weak pull-
down (approximately 50 k) which is only present during power on reset. Opposing this pull-down will
increase the power-down current.
18. Valid with the recommended capacitor values as shown in the typical connection diagram in Section 5.
2.1 Digital I/O Pin Characteristics
Input and output levels and associated power supply voltage are shown in Table 2. Logic levels should not
exceed the corresponding power supply voltage.
