Product Descriptions

ACM8622M 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 14.5V PVDD supply, 3.3V DVDD supply. lt can drive 2x10.5W output power into BTL 6 ohm and 1x23W into PBTL 4 ohm @1 percent THD+N.

ACM8622M 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 EMl noise. lt allows inductor free application with specified output power situation with ACM8622M.

The advanced audio effect tuning capability inside ACM8622M provides one highly integrated solution. lt allows turning on / off each block with highly free operations. Both pre and post BOs / volume helps a lot to maintain audio headroom.
