ACM8624 2×33W Stereo | 1×66W Mono, Digital Input Class-D Audio Amplifier with Audio Effect Tuning
ACM8624 is a fully integrated, high efficiency, stereo Class-D
audio amplifier with digital inputs. The application circuit
requires few passives components to operate with 4.5V to
26.4V PVDD supply, 3.3V or 1.8V DVDD supply. It can drive
2×33W output power into BTL 6Ω and 1×66W into PBTL
3Ω@1% THD+N.
ACM8624 features one novel PWM modulation architecture,
which adjusts PWM common duty cycle during start-up
phase to avoid startup pop click.
Spread spectrum technology provides lower EMI noise. It
allows inductor free application with specified output power
situation with ACM8624.
The advanced audio effect tuning capability inside ACM8624
provides one highly integrated solution. It allows turning on
/ off each block with highly free operations. Both BQs and
volume helps a lot to maintain audio headroom.
