TAS5036AIPFCR

Audio Special Purpose Overview

The TAS5036A is a six-channel digital pulse-width modulator (PWM) utilizing Equibit technology. It operates on a 3V to 3.6V supply and supports sampling rates from 32kHz to 192kHz. The device features I2C and I2S interfaces for control and audio data input. It includes six independent channels with volume control, mute, de-emphasis filters, and error recovery mechanisms. Designed for high-efficiency digital audio amplification, it interfaces directly with power stages or discrete MOSFETs in an all-digital signal chain.

Audio Special Purpose Feature Summary

• Six-channel PWM modulation with 100-dB SNR and <0.005% THD+N
• Supports 16-, 20-, and 24-bit input data formats including I2S, Left/Right Justified, and DSP
• Integrated I2C serial control interface for system configuration
• Built-in de-emphasis filter for 32 kHz, 44.1 kHz, and 48 kHz sample rates

Audio Special Purpose Applications

• Home theater systems such as HTIB and DVD receivers
• Digital audio amplification in TV sets
• Multi-channel speaker driver circuits using TI PurePath Digital power stages

Audio Special Purpose Procurement Notes

Verify the package type is 80-TQFP (PFC) and confirm the operating temperature range matches the specific suffix requirements. Ensure the source document confirms the 'A' variant specifications against standard TAS5036 models if critical performance margins are required for the design.

Audio Special Purpose Selection Notes

Select this component when a multi-channel digital front-end is needed for Class-D amplification. It requires external LC filters at speaker terminals. Verify compatibility with the chosen power stage (e.g., TAS51xx) and ensure the host processor supports the required I2S word lengths and clock configurations.

Audio Special Purpose Part Context

This device belongs to Texas Instruments' PurePath Digital audio amplifier family. It serves as the digital modulation stage preceding the power output stage. It is distinct from analog amplifiers by processing digital bitstreams directly, reducing analog noise susceptibility in the signal path up to the speaker load.

Audio Special Purpose Replacement Considerations

The TAS5036APFC is the commercial grade version (0°C to 70°C). For industrial temperature ranges (-40°C to 85°C), verify availability of equivalent variants or assess if the current thermal design accommodates the extended range without hardware changes.
