Note
The IRS2053M digital audio driver is a three channel
Class D audio driver housed in a 48 pin MLPQ. The
IRS2053M features clipping detection outputs, DC
offset detection input, over temperature sensor
inputs and a fault reporting output.

Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All
voltage parameters are absolute voltages referenced to COM; all currents are defined positive into any lead.
The Thermal Resistance and Power Dissipation ratings are measured under board mounted and still air
conditions.
