(1)Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied.

The PCM4108 is a high-performance, eight-channel digital-to-analog (D/A) converter designed for use in professional audio applications. The PCM4108 supports 16- to 24-bit linear PCM input data, with sampling frequencies up to 216kHz. The PCM4108 features lower power consumption, 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 PCM4108 features a multi-bit delta-sigma architecture, followed by 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 of PCM4108 are easily converted to a single-ended output using an external op amp IC.

The PCM4108 includes a flexible audio serial port interface, which supports standard and time division multiplexed (TDM) formats. In addition, the PCM4108 offers two configuration modes: Standalone and Software-Controlled. The Standalone mode provides dedicated control pins for configuring a subset of the available PCM4108 functions, while Software mode utilizes a serial peripheral interface (SPI) port for accessing the complete feature set via internal control registers.

The PCM4108 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 PCM4108 is available in a 64-lead HTQFP package.
