音频 IC 开发工具 TAS5518-5261K2EVM

The PurePath Digital™ customer evaluation amplifier module demonstrates two audio integrated circuits TAS5518 and TAS5261 from Texas Instruments .

TAS5518PAG is a high performance 32 bit 24 bit input multi channel PurePath Digital™ Pulse Width Modulator PWM based on Equibit™ technology with fully symmetrical AD modulation scheme. It will accept input sample rate from 32kHz to 192kHz. The device also has Digital Audio Processing DAP that provides 48 bit signal processing, advanced performance and a high level of system integration. The device has interfaces for headphone output and Power Supply Volume Control PSVC.

The TAS5261 is a high performance, integrated mono digital amplifier power stage designed to drive 4Ω to 8Ω speakers with low harmonic distortion. This system requires only a simple, passive demodulation filter to deliver high quality, high-efficiency audio amplification.

This EVM, together with a TI input-USB board, is a complete 2 channel stereo digital audio amplifier system which includes digital input S/PDIF, analog inputs, interface to PC and DAP features like digital volume control, input and output mixers, automute, tone controls, loudness, EQ filters and dynamic range compression DRC. There are configuration option for power stage failure protection and a mini-jack connector for headphone.

This stereo system is designed for home theater applications such as A/V receivers.
