192 kHz
101 dB Dynamic Range at 5 V
-94 dB THD+N
High-pass filter to remove DC offsets
Analog/digital core supplies from 3.3 V to 5 V

Low-latency digital filter
Auto-mode selection
Pin compatible with the CS5341
General Description
The CS5340 is a complete analog-to-digital converter for
digital audio systems. It performs sampling, analog-to-
digital conversion, and anti-alias filtering, generating
24-bit values for both left and right inputs in serial form at
sample rates up to 200 kHz per channel.
The CS5340 uses a 5th-order, multi-bit Delta-Sigma
modulator followed by digital filtering and decimation,
which removes the need for an external anti-alias filter.
The CS5340 is ideal for audio systems requiring wide dy-
namic range, negligible distortion and low noise, such as
set-top boxes, DVD-karaoke players, DVD recorders,
A/V receivers, and automotive applications.

CHARACTERISTICS AND SPECIFICATIONS
(All Min/Max characteristics and specifications are guaranteed over the Specified Operating Conditions. Typical
performance characteristics and specifications are derived from measurements taken at typical supply voltages
and T
A
= 25
C.)
SPECIFIED OPERATING CONDITIONS
(GND = 0 V, all voltages with respect to 0 V.)
Notes: 1. This part is specified at typical analog voltages of 3.3 V and 5.0 V. See
Analog Characteristics (CS5340-
CZ/CZZ)
and
Analog Characteristics (CS5340-DZZ),
below, for details.
ABSOLUTE MAXIMUM RATINGS
(GND = 0 V, All voltages with respect to ground.) (Note 4)
Notes: 2. Any pin except supplies. Transient currents of up to 100 mA on the analog input pins will not cause SRC
latch-up.
3. The maximum over/under voltage is limited by the input current.
4. Operation beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
