MA12070P
Filterless and High-Efficiency +4V to +26V
Audio Amplifier with I2S Digital Input
Description Features The MA12070P is a super-efficient audio power
amplifier based on proprietary multi-level switching
technology. It supports a 4-26V 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 MA12070P 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.
An integrated digital-to-analog converter enables
digital I2S audio stream input. It supports sample rates
from 44.1 kHz to 192 kHz.
Highly flexible output stage configurations are offered,
ranging from four single-ended outputs to a single
parallel-BTL output.
The MA12070P features protection against DC, shortcircuits,
over-temperature …
