DESCRIPTION
The PCM4104 is a high-performance, four-channel
digital-to-analog (D/A) converter designed for use in
professional audio applications. The PCM4104 supports
16- to 24-bit linear PCM input data, with sampling
frequencies up to 216kHz. The PCM4104 features lower
power consumption than most comparable stereo audio
D/A converters, making it ideal for use in high channel
count applications by lowering the overall power budget
required for the D/A conversion sub-system.
The PCM4104 features delta-sigma architecture,
employing a high-performance multi-level modulator
combined with a switched capacitor output filter. This
architecture yields lower out-of-band noise and a high
tolerance to system clock phase jitter. Differential voltage
outputs are provided for each channel and are well-suited
to high-performance audio applications. The differential
outputs are easily converted to a single-ended output
using an external op amp IC.
The PCM4104 includes a flexible audio serial port
interface, which supports standard and time division
multiplexed (TDM) formats. Support for TDM formats
simplifies interfacing to DSP serial ports, while supporting
a cascade connection for two PCM4104 devices. In
addition, the PCM4104 offers two configuration modes:
Standalone and Software-Controlled. The Standalone
mode provides dedicated control pins for configuring a
subset of the available PCM4104 functions, while
Software mode utilizes a serial peripheral interface (SPI)
port for accessing the complete feature set via internal
control registers.
The PCM4104 operates from a +5V analog power supply
and a +3.3V digital power supply. The digital I/O is
compatible with +3.3V logic families. The PCM4104 is
available in a TQFP-48 package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate
precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to
damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Dynamic performance parameters are measured using an Audio Precision System Two Cascade or Cascade Plus test system. Input data word
length is 24 bits with triangular PDF dither added for dynamic range and THD+N tests. Idle channel SNR is measured with both the soft and
zero data mute functions disabled and 0% full-scale input data with no dither applied. The measurement bandwidth is limited by using the Audio
Precision 10Hz high-pass filter in combination with either the AES17 20kHz low-pass filter or AES17 40kHz low-pass filter. All A-weighted
measurements are performed using the Audio Precision A-weighting filter in combination with either the 22kHz or 80kHz low-pass filter.
Measurement mode is set to RMS for all parameters. The AVERAGE measurement mode will yield better typical performance numbers.
(2) Idle Channel SNR is not limited by word length.
