ABSOLUTE MAXIMUM RATINGS

PCM4104-EP

SBAS419 – JUNE 2007

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 216 kHz. 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 subsystem.

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 5-V analog power supply and a 3.3-V digital power supply. The digital I/O is

compatible with 3.3-V 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.
