DESCRIPTION
The PCM4204 is a high-performance, four-channel analog-to-digital (A/D) converter designed for professional and broadcast audio applications. The PCM4204 architecture utilizes a 1-bit delta-sigma modulator per channel incorporating a novel density modulated dither scheme for improved dynamic performance. The PCM4204 supports 24-bit linear PCM output data, with sampling frequencies up to 216kHz. The PCM4204 can also be configured to output either 64x or 128x oversampled, 1-bit direct stream digital (DSD) data for each channel. In addition, the PCM4204 supports a DSD input mode, allowing 1-bit DSD to 24-bit PCM data format conversion utilizing the on-chip digital decimation filter. These features make the PCM4204 suitable for a variety of digital audio recording and processing applications. The PCM4204 includes a flexible audio serial port inter- face, which supports standard PCM audio data formats, as well as time division multiplexed (TDM) PCM data formats. Multiple format support allows the system designer to choose the interface format that best suits the end applica- tion. Audio data format selection, sampling mode configu- ration, and high-pass filter functions are all programmed using dedicated control pins. The PCM4204 operates from a +5V analog power supply and a +3.3V digital power supply. The digital I/O pins are compatible with +3.3V logic families. The PCM4204 is available in a thermally-enhanced HTQFP-64 PowerPAD package. PowerPAD is a registered trademark of Texas Instruments.

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.

When the thermal pad is soldered directly to the printed circuit board (PCB), the PCB can be used as a heatsink. In addition, through the use of thermal vias, the thermal pad can be attached directly to a ground plane or special heatsink structure designed into the PCB. This design optimizes the heat transfer from the integrated circuit (IC). The exposed thermal pad dimensions for this package are shown in the following illustration. For additional information on the PowerPAD package and how to take advantage of its heat dissipating abilities, refer to Technical Brief, PowerPAD Thermally Enhanced Package, Texas Instruments Literature No. SLMA002 and Application Brief, PowerPAD Made Easy , Texas Instruments Literature No. SLMA004.
