EUA2510A
Low EMI 2.7W Boosted Class-D
Audio Power Amplifier
DESCRIPTION
The EUA2510A integrates a current-mode boost converter
with a high efficiency mono, Class D audio power amplifier
to provide 2.7W/10% THD or 2W/1% THD continuous
power into a 4Ω speaker when operating on a 3.3V power
supply with boost voltage (PV1) of 5V. The Class D
amplifier is a low noise, filterless PWM architecture that
eliminates the output filter, reducing external component
count, board area consumption, system cost, and simplifying
design.
The EUA2510A’s boost converter, operating at a fixed
frequency of 600KHz, generates a high voltage rail which is
used to supply the Class-D amplifier. The EUA2510A
features a low-power consumption shutdown mode.
Shutdown may be enabled by driving the Shutdown pin to a
logic low (GND).
The gain of the Class D is externally configurable which
allows independent gain control from multiple sources by
summing the signals. Output short circuit and Thermal
shutdown protection prevent the device from damage during
fault conditions. Superior click and pop suppression
eliminates audible transients during power-up and shutdown.
