EUA2306
20-W Stereo Digital Audio Power Amplifier
DESCRIPTION
The EUA2306 is a 20-W, digital audio power amplifier
with 4 half-bridged power drivers. The EUA2306 is a slave
device that all clocks are provided by the external sources.
One serial data input allows processing of up to two
discrete audio channels and seamless integration to most
digital audio processors. A bidirectional I²C interface
allows reading or writing to change the internal register
status.
The EUA2306 also features short-circuit and thermal
protection preventing the device from being damaged
during a fault condition. The EUA2306 is available in
thermally efficient 48-pin TQFP package.
