TAS3218IPZP

Digital Signal Processor Dsp Overview

The Texas Instruments TAS3218IPZP is a digital audio processor with analog interface, housed in a 100-pin HTQFP (PZP) package. It operates within a temperature range of -40°C to +85°C and utilizes a single 3.3-V power supply. The device features a 48-bit data path with a 76-bit accumulator and supports up to 135-MHz operation for six channels. It includes three synchronous serial audio inputs and two outputs, handling 16-, 20-, or 24-bit data formats. The unit integrates an embedded 8051 WARP microprocessor, ten multiplexed stereo analog inputs, and three stereo audio DACs with typical dynamic noise ratios of 97 dB.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix PZP corresponds to the 100-pin TQFP package and the IPZP variant indicates the industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design specifications align with the single 3.3-V power supply requirement and internal regulator constraints.

Digital Signal Processor Dsp Selection Notes

Select this component for designs requiring a programmable audio DSP with integrated analog I/O. The device supports master and slave clock modes via external crystal or MCLKIN input. Consider the 100-pin package size and thermal characteristics for PCB layout. Verify that the required number of serial audio interfaces and analog channels matches the available pins and internal multiplexing capabilities.

Digital Signal Processor Dsp Part Context

The TAS3218 is part of the TAS3218I series, designed as a system-on-chip for audio processing. It combines digital signal processing with analog conversion and amplification functions. The device is distinct from other TAS series components by its specific integration of an 8051 controller and analog line drivers within a single TQFP package.
