TAS5015PFBG4

Audio Special Purpose Overview

The TAS5015PFBG4 is a stereo PCM-PWM modulator designed for high-quality digital audio amplification systems. It converts serial PCM digital audio streams into 3.3-V PWM signals using Equibit technology. The device supports 16-, 20-, or 24-bit input data and sampling rates up to 192 kHz. Key electrical specifications include a dynamic range of 112 dB and THD+N less than 0.01%. It operates on a 3V to 3.6V supply within an ambient temperature range of 0°C to 70°C. The component is housed in a 48-TQFP (7x7) package.

Audio Special Purpose Feature Summary

• 112-dB dynamic range with THD+N < 0.01%
• Supports 16, 20, and 24-bit input data formats
• Compatible with sampling rates from 44.1 kHz to 192 kHz
• Includes de-emphasis filter for 44.1-kHz and 48-kHz rates

Audio Special Purpose Applications

• Integrated Amplifiers
• AV Receivers
• Car Audio Systems

Audio Special Purpose Procurement Notes

Verify the NRND status indicating the part is not recommended for new designs. Confirm RoHS compliance and lead finish details via official documentation. Ensure the G4 suffix aligns with specific manufacturing requirements for the target application.

Audio Special Purpose Selection Notes

Select this component for applications requiring a discrete back-end TDAA power output stage. Verify compatibility with external PLL configurations for optimal performance. Ensure the system design accommodates the required 3.3-V logic levels and differential PWM output connections.

Audio Special Purpose Part Context

The TAS5015 is part of Texas Instruments' True Digital Audio Amplifier family. It functions as the modulation stage, working in conjunction with discrete H-bridge power devices to drive loudspeakers efficiently. This architecture separates the digital processing from the high-power analog output stage.
