STEREO DIGITAL AMPLIFIER POWER STAGErequiresa simple passive LC demodulation filterto
deliver high-quality, high-efficiency audio amplification•
2×100Wat 10% THD+N Into 4-Ω BTL(1)with proven EMI compliance. This device requires two•
2×80Wat 10% THD+N Into 6-Ω BTL power supplies,at 12V for GVDD and VDD, andatV for PVDD. The TAS5142 does not require•
2×65Wat 10% THD+N Into 8-Ω BTLpower-up sequencing dueto internal power-on reset.•
4×40Wat 10% THD+N Into 3-Ω SE The efficiencyof this digital amplifieris greater than•
4×30Wat 10% THD+N Into 4-Ω SE 90% into6 Ω, which enables the use of smaller•
1×160Wat 10% THD+N Into 3-Ω PBTL power supplies and heatsinks.
1×200Wat 10% THD+N Into 2-Ω PBTL(1) The TAS5142 has an innovative protection system
integrated on-chip, safeguarding the device againsta•
>100 dB SNR (A-Weighted)wide rangeof fault conditions that could damage the•
<0.1% THD+Nat1W system. These safeguards are short-circuit protection,•
Two Thermally Enhanced Package Options: overcurrent protection, undervoltage protection,
DKD (36-pin PSOP3) overtemperature protection. The TAS5142 hasa new
proprietary current-limiting circuit that reduces
