GENERAL DESCRIPTION
1.1 Overview Compared to traditional Class D amp, the NAU83G20 has 2 ADCs integrated such that speaker voltage and current can be sensed and sent back to the DSP for speaker excursion control. This speaker excursion control can prevent the speaker membrane excursion from exceeding its rated limit and provide ample headroom for overall loudness and sound quality. 1.2 FEATURES
The NAU83G20 Monophonic Amplifier, with DSP and I/V Sense, and utilizes a powerful Class-D Amplifier. The chip features high output power capability, low-current shutdown mode, and click-and-pop suppression. Equipped with a DSP Core, numerous types of device protection schemes are supported, as well as speaker protection schemes, including ambient temperature monitoring input for enhanced speaker module design. The temperature monitoring in the NAU83G20 protects both the chip and the speaker from overheating. The chip is available in a 50-ball Wafer Level Chip Scale Package (WLCSP). Key Feature...
