TAS5076PFCR

Audio Special Purpose Overview

The TAS5076PFCR is a six-channel digital pulse-width modulator (PWM) from Texas Instruments, part of the PurePath Digital series. It utilizes Equibit technology to drive up to six digital power devices for high-efficiency audio amplification. The device supports serial audio interfaces including I2S, Left Justified, Right Justified, and DSP formats with 16-, 20-, or 24-bit word lengths. It operates on a 3V to 3.6V supply within an operating temperature range of 0°C to 70°C. Key specifications include a dynamic range of up to 105 dB for front channels and <0.005% THD+N. It features independent volume control, mute, de-emphasis filters, and error recovery mechanisms.

Audio Special Purpose Feature Summary

• Six-channel PWM modulation using Equibit technology for high efficiency
• Supports multiple serial data formats: I2S, Left/Right Justified, and DSP
• Integrated I2C serial control interface for configuration
• Features soft volume, soft mute, and automute capabilities

Audio Special Purpose Applications

• Home theater systems
• DVD minicomponent systems
• Home theater in a box (HTIB)
• A/V receivers

Audio Special Purpose Procurement Notes

Verify the package type matches the required 80-TQFP form factor. Confirm the operating temperature range aligns with system requirements, as this variant is rated for 0°C to 70°C. Ensure the ordering suffix corresponds to the Tape & Reel packaging option if automated assembly is planned. Cross-reference the datasheet revision date to confirm compatibility with current design standards.

Audio Special Purpose Selection Notes

Select this component when a multi-channel digital audio solution is needed without internal power stages. It requires external power devices such as the TAS5110 or discrete MOSFETs. Verify that the host processor can support the required serial clock rates and data formats. Consider the need for external PLL filtering components if operating in master mode.

Audio Special Purpose Part Context

This device belongs to the Texas Instruments PurePath Digital family, designed to work in conjunction with specific power amplifier stages. It serves as the digital processing core for converting PCM audio data into PWM signals. The PFC suffix indicates the plastic TQFP package variant. It is distinct from integrated amplifier chips as it focuses solely on modulation and control.
