MA12040
Filterless and High-Efficiency +4V to +18V
Audio Amplifier with Analog Input
Description Features The MA12040 is a super-efficient audio power amplifier
based on proprietary multi-level switching technology.
It supports a wide supply voltage range, allowing it to
be used in many different applications. • Multi-level switching enables very low power loss
during operation. In addition, it allows the amplifier to
be used in filterless configurations at full rated power
in a wide range of audio products.
The MA12040 features an embedded digital power
management scheme. The power management
algorithm dynamically adjusts switching frequency and
modulation to optimize power loss and EMI across the
output power range. • • A 4th order feedback loop ensures low distortion and a
high PSRR.
The MA12040 operates from a single power stage
supply voltage (PVDD) and a 5V system supply voltage
(DVDD, AVDD). • Highly flexible output stage configurations are offered,
ranging from four single-ended outputs to a single
parallel-BTL output. • The MA12040 features protection against DC, shortcircuits,
over-temperature
and …
