TI Delivers Industry's Highest Performance Four-Channel Audio DAC from Burr-Brown Pro Audio Product Line

Posted on: Friday, 16 April 2004, 06:00 CDT

TUCSON, Ariz., April 16 /PRNewswire/ -- Texas Instruments Incorporated (TI) today introduced a four-channel, 24-bit audio digital-to- analog converter (DAC) from the company's Burr-Brown Pro Audio product line which features 118dB dynamic range, -100dB total harmonic distortion and up to 200kHz sampling. The PCM4104 is designed for professional audio applications, such as digital mixing consoles, digital effects processors, multi-track recorders, broadcast studio equipment, surround sound processors and high-end A/V receivers. (See http://www.ti.com/sc04100 .)

"The PCM4104 is the industry's highest performance four-channel audio DAC. There is no other audio DAC on the market that offers this level of integration and performance," said Mike Centorino, marketing manager for TI's Burr-Brown Pro Audio products. "The PCM4104 also features low-power operation with 200mW total power consumption for all four channels, while competitive high-performance audio DACs consume the same power for only two channels."

The low power consumption of the PCM4104 makes it ideal for high channel count applications by lowering the overall power budget required for the digital-to-analog conversion subsystem.

The PCM4104 employs delta-sigma technology with a high-performance, multi- level modulator and 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 (6.15Vp-p) 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 operational amplifier IC.

The PCM4104 includes a flexible audio serial port interface, which supports standard and time division multiplexed (TDM) data formats. Support for TDM formats simplifies interfacing to an audio DSP, such as TI's C6713 Pro Audio DSP, while supporting a cascade connection of several PCM4104 devices.

The device offers two configuration modes: standalone and software controlled. Standalone mode provides dedicated control pins for configuring a subset of the available 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.

Available Today

The PCM4104 is packaged in a 48-lead TQFP and is available now from TI and its authorized distributors. An evaluation module (EVM) is also available.
