1 Introduction

The TAS5000 is an innovative, cost-effective, high-performance 24-bit stereo digital modulator based on Equibit



technology. This product converts input PCM serial digital audio data to an output PWM audio data stream. The

TAS5000 is designed to be connected to two TAS5100 mono true digital amplifiers for driving loudspeakers. This

all-digital audio system contains only two analog components in the signal chain—an L-C low-pass filter at the

speaker terminals. It can provide up to 90 dB SNR at the speaker terminals. It has a wide variety of serial input options

including right justified (16, 20, or 24-bit), IIS (16, 20, or 24-bit), left justified (16-bit), or DSP (16-bit) data formats. It

is fully compatible with AES standard sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz including providing

de-emphasis for 44.1 kHz, and 48 kHz sample rates. The TAS5000 and TAS5100 system can be used in a range of

products such as microcomponent systems, PC speakers, home theater in a box, convergence products, A/V

receivers, or TV sets.
