Introduction
The TAS5026 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 TAS5026 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 TAS5110) or six discrete differential power stages using gate drivers and
MOSFETs.
The TAS5026 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 mode.
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 TAS5026 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 TAS5026 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.
