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

FEATURES

•

2×20 W at 10% THD+N Into 8-Ω BTL at 18 V

(With Heatsink for TAS5102)

•

2×15 W at 10% THD+N Into 8-Ω BTL at 15.5 V

for TAS5103

to deliver high-quality,

high-efficiency

audio

amplification with proven EMI compliance. These

devices require two power supplies, at 3.3 V for

2×10 W at 10% THD+N Into 8-Ω BTL at 13 V

>100-dB SNR (A-Weighted)

VREG, and up to 23

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.
