TAS5026APAGR

Audio Special Purpose Overview

The Texas Instruments TAS5026APAGR is a six-channel digital pulse width modulator (PWM) processor based on 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. Key electrical specifications include a signal-to-noise ratio of 96 dB and total harmonic distortion plus noise below 0.1%. It features integrated volume control, mute functions, de-emphasis filters, and error recovery mechanisms for high-efficiency digital audio amplification.

Audio Special Purpose Feature Summary

• Six independent PWM channels with individual volume and mute controls
• Supports 16-, 20-, and 24-bit input data formats including I2S and DSP
• Integrated low-jitter PLL and clock oscillator circuit
• Digital de-emphasis filter for 32 kHz, 44.1 kHz, and 48 kHz sample rates

Audio Special Purpose Applications

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

Audio Special Purpose Procurement Notes

Verify the package type matches the required PCB footprint, as the standard variant uses a 64-pin TQFP. Confirm the temperature range specification aligns with the application environment, noting that the 'C' suffix indicates commercial grade (0°C to 70°C). Ensure the ordering suffix corresponds to the specific tape and reel configuration required for automated assembly processes.

Audio Special Purpose Selection Notes

Select this component when designing multi-channel digital audio systems requiring high efficiency and low jitter. It is suitable for applications needing up to six speaker outputs driven by external power stages. Consider the interface compatibility with the host microcontroller or DSP, specifically regarding master/slave clock modes and supported serial data protocols like I2S or DSP format.

Audio Special Purpose Part Context

The TAS5026 belongs to Texas Instruments' PurePath Digital audio solutions family. It is designed to work in conjunction with TI digital amplifier power stages, such as the TAS5110 or TAS5182, to form a complete all-digital audio system. This architecture minimizes analog components in the signal chain, relying primarily on LC filters at the speaker terminals.
