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
24-bit PCM input data, with sampling frequencies up to
192kHz. The PCM4104 features lower power than
comparable stereo audio D/A converters, making it ideal
for use in high channel count systems, lowering the overall
power budget required for D/A conversion by more than
50%.
The PCM4104 features a multi-level, delta-sigma
architecture with a switched capacitor output filter, which
gives a high tolerance to clock jitter. The differential
voltage outputs are well suited to high-performance audio
applications, and are easily converted to a single-ended
output using a single op amp per channel.
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. In addition, the
PCM4104 offers two operating modes: Standalone and
Software-Controlled. The Standalone mode provides
dedicated control pins for configuring a limited set of
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, and is not +5V tolerant. 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.
