DESCRIPTION
Technology
The device is a two-channel digital audio amplifier
Patented AM Interference Avoidance
designed for use in automotive head units and
external amplifiers. It provides two channels at 28 W
Patented Cycle-by-Cycle Current Limit
into 4
Ω at 10% THD+N from 14.4 V or 46 W into 2 Ω
75-dB PSRR
at 10% THD+N. The digital PWM topology provides
Four-Address I2C Serial Interface for Device
dramatic improvements in efficiency over traditional
Configuration and Control
linear amplifier solutions. This reduces the power
dissipated by the amplifier by a factor of ten under
