GENERAL DESCRIPTION
The CM8685 is a single channel monolithic Class D Plus and feed forward compensation techniques to achieve better THD+N. The CM8685 integrated four power MOSFETs to drive bridge tight load output. They are guaranteed no shot through, adaptively control break before make. The CM8685 can deliver peak output power of up to 5 watts at 4Ω load from a single 5V power supply in the high fidelity range (20 Hz to 20kHz). The CM8685 incorporated a green mode function to ensure high efficiency at light load and full load. The CM8685 has the optimal high efficiency of up to 90% and no heat sink required. The efficient Class D Plus temperature of 40 ℃. Low supply current of 3mA makes the device ideal for battery-powered applications. CM8685 is packaged in a 8-pin PSOP and PDIP package saves the system space.
