TAS5076PFC

Audio Special Purpose Overview

The TAS5076PFC is a six-channel digital pulse-width modulator (PWM) utilizing Equibit technology. It operates on a single 3.3-V supply and supports sampling rates from 32 kHz to 192 kHz. The device accepts 16-, 20-, or 24-bit serial audio data via I2S, Left Justified, Right Justified, or DSP formats. It features an internal PLL, de-emphasis filters, and individual channel volume control with soft mute capabilities. Packaged in an 80-TQFP (12x12 mm) case, it is designed for home theater systems.

Audio Special Purpose Feature Summary

• Six independent PWM channels with up to 105-dB dynamic range
• Supports 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz sample rates
• Integrated de-emphasis filter for 32 kHz, 44.1 kHz, and 48 kHz
• I2C serial control interface for system configuration

Audio Special Purpose Applications

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

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'PFC' corresponds to the 80-pin TQFP plastic package and the 0°C to 70°C operating temperature range. Confirm that the component meets the required RoHS compliance standards for the target assembly process.

Audio Special Purpose Selection Notes

Select this component when a multi-channel digital modulation solution is required for direct drive of power stages. Ensure the host system provides compatible serial audio interfaces (I2S/LJ/RJ/DSP) and an I2C bus for control. Verify that the 3.3-V logic levels match the system voltage requirements.

Audio Special Purpose Part Context

This device belongs to the Texas Instruments PurePath Digital family. It is intended to be paired with TI power amplifier stages, such as the TAS5110, to form a complete all-digital audio amplification system. The architecture relies on noise-shaping algorithms to achieve high efficiency and performance.

Audio Special Purpose Replacement Considerations

The TAS5036 is a similar six-channel digital PWM processor within the same product family. Verify pin compatibility and software register mapping before substitution.
