• High-Performance Digital Audio Input: Features an I2S Serial Digital Audio Input Interface supporting a wide sample rate range from 8 kHz to 96 kHz, with automatic sample rate detection.

• Efficient, Filterless Class D Architecture: Utilizes a Filterless Class D amplifier with high efficiency (80% at 2.5W) and low distortion (0.2% THD at 1W) for power-sensitive portable devices.

• Advanced Audio Control & Processing: Includes a Distortion Prevention (NCN) function and a built-in Digital High-Pass Filter (HPF) whose cutoff frequency can be set with a simple single-wire pulse.

• Robust Protection and Noise Suppression: Offers comprehensive protection mechanisms (Overcurrent, Over-Temperature, and Undervoltage Protection) alongside excellent Power-Up/Power-Down Noise Suppression (anti-pop/click).

• Robust Protection and Noise Suppression: Offers comprehensive protection mechanisms (Overcurrent, Over-Temperature, and Undervoltage Protection) alongside excellent Power-Up/Power-Down Noise Suppression (anti-pop/click).

• Optimized for Portability and Thermal Management: Built around the NS4168 chip in an eSOP8 packaging (Enhanced SOP with Exposed Pad) design, making it ideal for compact applications requiring superior thermal performance.

Brief introduction

The I2S audio amplifier module uses the NS4168 as the main control chip. It is a high-efficiency, low-noise and highly integrated Class D audio power amplifier module, which is especially suitable for portable audio devices with high requirements for power consumption and anti-interference. Its I2S digital input, anti-distortion function and rich protection mechanisms endow it with broad application prospects in consumer electronics products.
