The following is a circuit diagram of the [Si2704/05/06/07 Typical Application Circuit Diagram].
The Si2704/05/06/07 is a high-performance digital audio processing Class D amplifier designed to minimize EMI and simplify system design. It integrates the power stage, PWM DAC, and digital audio processing (DAP) into a single chip, making it ideal for cost-effective and energy-efficient solutions. With a digital input Delta-Sigma PWM architecture, the Si270x series features a patent-pending EMI-reduction technology and an AM-band noise-free notch filter. This allows it to deliver up to 2 x 5W of power to a 3Ω load in BTL mode, with an efficiency of 88% when PSRR exceeds 50dB. Additionally, it offers a dynamic range of 95dB with THD better than 0.1%. These devices are widely used in portable media players (PMP), MP3 docking stations, handheld consumer electronics, active or wireless speakers, TVs, monitors, and TV sound cards.
