Description: 1. The TPA3118 is a high-performance, mono, digital power amplifier chip designed for Class D audio applications in IoT devices. 2. It features a 24-bit, sigma-delta modulator that ensures low distortion and high efficiency, making it ideal for small form factor systems. 3. The TPA3118 is capable of delivering up to 6 Watts RMS into an 8Ω load, with a maximum output power of 15W peak-to-peak. 4. It includes an integrated power supply and protection circuitry, eliminating the need for external components in many applications. 5. This amplifier offers low power consumption, typically around 0.3 Watts in standby mode and 2.65 Watts when active, which is a significant benefit for battery-operated devices. 6. The TPA3118 supports both AC-coupled and DC-coupled output configurations, providing flexibility for various system designs. 7. Its small form factor, with an 8mm x 9mm footprint, makes it suitable for compact IoT devices and wearables. 8. The amplifier comes with built-in ther
