TAS5010IPFBRG4

Audio Special Purpose Overview

The TAS5010IPFBRG4 is a stereo PCM-to-PWM modulator designed for True Digital Audio Amplifier (TDAA) systems. It accepts serial digital audio inputs and converts them into differential 3.3-V PWM signals compatible with the TAS5100 power stage. The device supports 16-, 20-, or 24-bit data formats at sampling rates up to 192 kHz. Key electrical specifications include a 96-dB dynamic range, THD+N less than 0.08%, and a supply voltage range of 3 V to 3.6 V. It operates within an automotive temperature range of -40°C to 85°C and utilizes a 48-pin TQFP package.

Audio Special Purpose Feature Summary

• Equibit modulation technology delivering 96-dB dynamic range and <0.08% THD+N
• Supports standard serial interfaces including IIS, DSP, right-justified, and left-justified formats
• Integrated low-jitter PLL and digital interpolation filter for high-fidelity audio processing
• Automotive-grade qualification with operation from -40°C to 85°C

Audio Special Purpose Applications

• Car audio amplifiers and head units
• Home theater systems
• DVD-Audio players
• Mini/micro component systems

Audio Special Purpose Procurement Notes

Verify the 'R' suffix indicates Tape & Reel packaging rather than Tray. Confirm the 'G4' suffix denotes RoHS compliance and lead-free status as per Texas Instruments standards. Ensure the specific grade matches automotive requirements if deployed in vehicle electronics. Cross-reference the full part number against current TI availability lists to confirm active status.

Audio Special Purpose Selection Notes

Select this component when designing a TDAA system requiring a dedicated modulator paired with a TAS5100 output stage. It is suitable for applications demanding high efficiency and low distortion in automotive environments. Verify that the host processor can provide the required MCLK, SCLK, and LRCLK signals for the chosen serial interface mode.

Audio Special Purpose Part Context

This device belongs to the TAS5000/TAS5100 family of True Digital Audio Amplifiers. It functions specifically as the PCM-PWM modulator, while the TAS5100 serves as the power output stage. The IPFB designation identifies the industrial/automotive temperature variant in a 48-pin TQFP package. The RG4 suffix specifies the reel packaging and environmental compliance.

Audio Special Purpose Replacement Considerations

TAS5010IPFB: Identical function but packaged in trays instead of reels.

Audio Special Purpose FAQ

What is the maximum sampling rate supported by the TAS5010?

The device supports sampling rates up to 192 kHz, which is automatically detected in slave mode.

How does the TAS5010 handle mute functions?

It provides a quiet mute feature where asserting the MUTE pin low results in a 50% duty cycle on the differential PWM outputs.

What serial data formats are available?

The TAS5010 supports 16-, 20-, and 24-bit right-justified, 16-, 20-, and 24-bit IIS, 16-bit left-justified, and 16-bit DSP frame formats.
