TAS5036

Introduction

The TAS5036 is an innovative, cost-effective, high-performance 24-bit six-channel digital pulse width

modulator (PWM) based on Equibit

 technology. Combined with a TI digital amplifier power stage, these

devices use noise-shaping and sophisticated error correction algorithms to achieve high power efficiency and

high-performance digital audio reproduction. The TAS5036 is designed to drive up to six digital power devices

to provide six channels of digital audio amplification. The digital power devices can be six conventional

monolithic power stages (such as the TAS5110) or six discrete differential power stages using gate drivers

and MOSFETs.

The TAS5036 has six independent volume controls and mute. It is designed to drive a digital amplifier power

stage (such as the TAS5182) in an H-bridge (bridge tied load) configuration. The device operates in AD and

BD modes. This all-digital audio system contains only two analog components in the signal chain—an LC

low-pass filter at each speaker terminal and can provide up to 96-dB SNR at the speaker terminals. The

TAS5036 has a wide variety of serial input options including right justified (16, 20, or 24 bit), I2S (16, 20, or

24 bit) left justified, or DSP (16-bit) data formats. The device is fully compatible with AES standard sampling

rates of 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz including de-emphasis for 44.1-kHz and

48-kHz sample rates. The TAS5036 plus the TAS51xx power stage device combination was designed for

home theater applications such as DVD minicomponent systems, home theater in a box (HTIB), DVD receiver,

A/V receiver, or TV sets.
