TAS5066PAGRG4

Audio Special Purpose Overview

The TAS5066PAGRG4 is a six-channel digital pulse width modulator (PWM) utilizing Equibit technology. It operates on a 3.3-V supply and supports sampling rates from 32 kHz to 192 kHz, including AES standards like 44.1 kHz and 96 kHz. The device accepts 16-, 20-, or 24-bit serial audio data via I2S, Left/Right Justified, or DSP formats. Key electrical parameters include a 97-dB dynamic range and less than 0.05% THD+N. It features independent volume control, mute, de-emphasis filtering, and an internal PLL for clock generation in master mode.

Audio Special Purpose Feature Summary

• Six-channel PWM output with up to 97-dB dynamic range
• Supports 32 kHz to 192 kHz sampling rates and 16/20/24-bit word lengths
• Integrated I2C serial control interface for configuration
• Internal PLL and clock oscillator circuitry

Audio Special Purpose Applications

• Home theater systems
• DVD minicomponent systems
• A/V receivers

Audio Special Purpose Procurement Notes

Verify the 'RG4' suffix against current Texas Instruments documentation to confirm RoHS compliance and lead-free status. Confirm package availability as the standard PAG variant is listed in the datasheet. Ensure the specific ordering code matches the required temperature grade of 0°C to 70°C.

Audio Special Purpose Selection Notes

Select this component for applications requiring multi-channel digital amplification without external DACs. Verify that the system design accommodates the 64-TQFP package dimensions. Ensure the power supply provides stable 3.3 V for both analog and digital sections. Check compatibility with the intended serial audio protocol (I2S, Left/Right Justified, or DSP).

Audio Special Purpose Part Context

This part belongs to the Texas Instruments PurePath Digital Audio family. It functions as a digital front-end for Class-D amplifier stages, driving external power devices such as the TAS5111 monolithic power stage or discrete MOSFET H-bridges. The device replaces traditional analog signal chains by integrating digital processing directly before the power stage.
