TAS5001PFBRG4

Audio Special Purpose Overview

The TAS5001PFBRG4 is a stereo PCM-PWM modulator from the Texas Instruments TAS5001 series, designed for high-quality digital audio amplification. It operates on a single 3V to 3.6V supply and features a 96dB dynamic range with THD+N below 0.08%. The device accepts 16-, 20-, or 24-bit serial PCM data at sampling rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz. Packaged in a 48-TQFP (7x7 mm) surface-mount format, it includes an internal low-jitter PLL, digital interpolation filter, and Equibit modulation technology.

Audio Special Purpose Feature Summary

• Stereo PCM-to-PWM Modulation: Converts digital audio streams into differential 3.3-V PWM signals using Equibit technology.
• High Audio Performance: Delivers 96dB dynamic range and less than 0.08% THD+N.
• Flexible Serial Interface: Supports IIS, right-justified, left-justified, and DSP formats via MOD pins.
• Integrated Clocking: Features a low-jitter PLL and supports master/slave clocking modes.

Audio Special Purpose Applications

• DVD Audio Systems
• Home Theater Amplifiers
• Car Audio Amplifiers and Head Units
• Internet Music Appliances

Audio Special Purpose Procurement Notes

Verify the 'R' suffix indicates Tape & Reel packaging rather than bulk. Confirm the operating temperature grade matches the application requirements, as the datasheet lists both commercial (0°C to 70°C) and industrial (-40°C to 85°C) variants. Ensure the specific revision level aligns with current design specifications.

Audio Special Purpose Selection Notes

Select this component when a dedicated PCM-PWM modulator is required for a True Digital Audio Amplifier system paired with a power stage like the TAS5100. Consider the 48-pin TQFP package constraints and the need for external PLL filtering components. Verify compatibility with the host processor's serial audio interface timing.

Audio Special Purpose Part Context

This part belongs to the TAS5001 family of True Digital Audio Amplifiers. It functions as the signal processing front-end, converting PCM data to PWM, while typically driving a separate power output device such as the TAS5100 H-Bridge. The PFBRG4 designation specifies the 48-TQFP package, reel packaging, and lead-free/RoHS compliance.
