20-W/15-W STEREO DIGITAL AMPLIFIER POWER STAGE  
A low-cost, high-fidelity audio system can be built  
using a TI chipset, comprising a modulator (e.g.,  
TAS5086) and the TAS5102/TAS5103. This system  
only requires a simple passive LC demodulation filter

for PVDD. The  
TAS5102/TAS5103 does not require power-up  
sequencing due to internal power-on reset. The  
efficiency of this digital amplifier is greater than 90%  
into 8 Ω, which enables the use of smaller power  
supplies and heatsinks.

The TAS5102/3 has an innovative protection system  
integrated on chip, safeguarding the device against a  
wide range of fault conditions that could damage the  
system. These safeguards are short-circuit protection,  
overcurrent protection, undervoltage protection, and  
overtemperature protection. The TAS5102/TAS5103  
has a new proprietary current-limiting circuit that  
reduces the possibility of device shutdown during  
high-level music transients.

DESCRIPTION  
The TAS5102/TAS5103 are integrated stereo digital  
amplifier power stages with an advanced protection  
system. The TAS5102/TAS5103 are capable of  
driving an 8-Ω bridge-tied load (BTL) at up to 20  
W/15 W per channel with low integrated noise at the  
output, low THD+N performance, and low idle power  
dissipation.
