General Description
The ACM8822 device is a four-channel high-efficient
class-D amplifier with digital input, low EMI output
stages.
The ACM8822 supports start stop cranking down to
4.5V and compatible with 40V load dump.
The ACM8822 supports 16/24/32-bit data, I2S-Bus,
and TDM with 4, 8, or 16 slots per frame. High
resolution bandwidth supports up to 20kHz (I2S
48kHz) , 40kHz (I2S 96kHz) and 80kHz (I2S 192kHz).
There are a large number of protection features
integrated in to ACM8822, intended to protect the
device, speaker and system against fault events like
Short circuit protection, Over temperature protection,
Speaker DC protection, Battery load dump protection,
Over/under voltage protection, Clock error Protection.
The device is offered in a very compact and thin LQFP
10mm×10mm package.
