TAS5000PFBG4

Audio Special Purpose Overview

The TAS5000PFBG4 is a stereo digital audio modulator from Texas Instruments, utilizing Equibit technology to convert PCM serial digital audio data into PWM streams. It supports 16-, 20-, or 24-bit input data at sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz. The device operates on a 3V to 3.6V supply and features an internal PLL for low-jitter clock generation. It provides up to 90 dB SNR and dynamic range at the speaker terminals. Designed for consumer audio applications, it interfaces via SPI-compatible serial formats including IIS, right/left justified, and DSP modes.

Audio Special Purpose Feature Summary

• Equibit-based digital PWM modulation with 90 dB SNR
• Supports 16/20/24-bit audio data at standard sampling rates
• Integrated low-jitter PLL and oscillator circuit
• Hardware-selectable serial interface formats (IIS, DSP, etc.)

Audio Special Purpose Applications

• Microcomponent systems
• PC speakers
• Home theater in a box
• A/V receivers

Audio Special Purpose Procurement Notes

Verify component authenticity as this part may be discontinued. Confirm package integrity upon receipt. Ensure design safeguards are implemented for application hazards. Check latest datasheet versions before ordering to verify current specifications and availability status.

Audio Special Purpose Selection Notes

Select based on required serial interface format (IIS, DSP, etc.) and sampling rate support. Ensure compatibility with TAS5100 amplifiers for complete system implementation. Verify power supply requirements (3V-3.6V) and operating temperature range (0°C to 70°C). Consider double-speed mode support if 88.2 kHz or 96 kHz operation is needed.

Audio Special Purpose Part Context

Part of the TAS5000 series of digital audio processors. Designed specifically for driving TAS5100 mono true digital amplifiers. Uses Equibit technology for high-efficiency Class-D-like performance with minimal analog components in the signal chain.

Audio Special Purpose Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Evaluate alternative TI audio DSPs or modulators based on pin compatibility and functional requirements.
