TAS3218PZPR

Digital Signal Processor Dsp Overview

The Texas Instruments TAS3218PZPR is a digital audio processor with analog interface, housed in a 100-pin TQFP (PZP) package. It operates at 135 MHz and features a 48-bit data path with a 76-bit accumulator. The device includes three synchronous serial audio inputs and two outputs supporting I2S, left-justified, and right-justified formats. It integrates an embedded 8051 WARP microprocessor, ten stereo analog line inputs, three stereo DACs, and a stereo headphone amplifier. Analog performance specifications include a typical dynamic noise ratio of 93 dB for the ADC and 97 dB for the DAC.

Digital Signal Processor Dsp Feature Summary

Digital Signal Processor Dsp Applications

• Digital television audio systems
• Mini/micro component audio applications

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix PZPR indicates the tape and reel packaging variant of the TAS3218PZP. Confirm the commercial temperature range of -20°C to 70°C matches the design requirements. Ensure the 100-pin TQFP footprint aligns with the PCB layout specifications provided in the datasheet.

Digital Signal Processor Dsp Selection Notes

Select this component for designs requiring a programmable audio DSP combined with integrated analog I/O. The device supports master or slave clock modes via external crystal or MCLKIN. Consider the 135 MHz processing speed and available RAM resources when designing complex audio algorithms.

Digital Signal Processor Dsp Part Context

The TAS3218PZPR is the tape and reel version of the TAS3218PZP. Both belong to the TAS3218 family of digital audio processors. The PZP suffix denotes the 100-pin Thin Quad Flatpack package type used by Texas Instruments for this series.

Digital Signal Processor Dsp Replacement Considerations

The TAS3218IPZPR serves as the industrial temperature grade (-40°C to 85°C) replacement for the commercial grade TAS3218PZPR.
