产品描述

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.
