TAS5036APFCR

Audio Special Purpose Overview

The TAS5036APFCR is a six-channel digital pulse-width modulator (PWM) utilizing Equibit technology. It operates on a 3V to 3.6V supply within a 0°C to 70°C temperature range. The device supports sampling rates from 32kHz to 192kHz and accepts 16-, 20-, or 24-bit input data via I2C and I2S interfaces. Key electrical specifications include a 100-dB signal-to-noise ratio and less than 0.005% THD+N. It features independent volume control, mute functions, de-emphasis filters, and error recovery mechanisms for high-performance digital audio amplification.

Audio Special Purpose Feature Summary

• Six-channel PWM modulation with 100-dB SNR and <0.005% THD+N
• Supports sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz
• Integrated I2C serial control interface for system configuration
• Built-in de-emphasis filter and soft volume/mute capabilities

Audio Special Purpose Applications

• Home theater systems including DVD minicomponent systems
• Home theater in a box (HTIB) units
• DVD receivers and A/V receivers
• TV sets with integrated digital audio processing

Audio Special Purpose Procurement Notes

Verify the package type is 80-TQFP (12x12 mm) and the operating temperature range is 0°C to 70°C. Confirm the device is supplied in Tape & Reel format. Ensure compatibility with 3.3V logic levels for the I2C control interface and check that the application design accommodates the required LC low-pass filters at speaker terminals.

Audio Special Purpose Selection Notes

Select this component for applications requiring up to six channels of digital audio amplification. It is suitable for designs needing support for standard AES sampling rates up to 192 kHz. The device requires an external PurePath Digital power stage, such as the TAS5110, to drive speakers. Designers must account for the 80-pin TQFP footprint and provide appropriate decoupling for AVDD and DVDD supplies.

Audio Special Purpose Part Context

This part belongs to Texas Instruments' PurePath Digital audio amplifier family. It serves as the digital front-end modulator, working in conjunction with analog power stages to create a complete digital audio amplification solution. The TAS5036A focuses on signal processing, modulation, and control, while the power stage handles high-current output.
