TAS5066PAGG4

Audio Special Purpose Overview

The TAS5066PAGG4 is a six-channel digital pulse width modulator (PWM) based on Equibit technology. It operates with a 3V to 3.6V supply and supports sampling rates from 32kHz to 192kHz. The device features I2C and I2S interfaces, providing independent volume control and mute for each channel. It delivers up to 97-dB dynamic range and less than 0.05% THD+N. Packaged in a 64-TQFP (10x10 mm), it is designed for home theater applications such as DVD minicomponent systems and A/V receivers.

Audio Special Purpose Feature Summary

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

Audio Special Purpose Applications

• DVD minicomponent systems
• Home theater in a box (HTIB)
• DVD receiver and A/V receiver
• TV sets

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's current datasheet to confirm compliance status and package details. Ensure the application environment remains within the specified 0°C to 70°C operating temperature range and 3V to 3.6V supply voltage limits.

Audio Special Purpose Selection Notes

Select this component for designs requiring six discrete digital audio channels without external DACs. Confirm compatibility with PurePath Digital power stages or discrete H-bridge drivers. Verify that the system master clock requirements align with the device's master/slave mode capabilities and supported sampling rates.

Audio Special Purpose Part Context

This part belongs to Texas Instruments' PurePath Digital audio amplifier family. It functions as a digital front-end modulator, converting serial digital audio data into PWM signals. It is typically paired with external power MOSFETs or monolithic power stages to complete the amplification chain.
