Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced a 20W mono Class-D audio amplifier in the space-saving SOP16 exposed-pad, surface-mount package. PAM8320’s low-impedance drive capability enables it to deliver 20W into a 4Ω bridge-tied-load speaker, making it suitable for a variety of high-power, small-enclosure speakers in wireless headphones, PCs and docking station products. The amplifier’s wide 4.5V to 15V supply range also means it performs equally well for battery cell and mains-driven consumer audio systems.
Operating at an efficiency of up 95%, the PAM8320 eliminates the need for an external heatsink, saving system space and reducing BOM cost. To help increase product reliability, this amplifier features a suite of safeguard circuitry, consisting of over-voltage and under-voltage lockout protection, thermal and short-circuit protection with auto recovery, as well as anti-pop circuitry to keep the speaker safe during power-on and power-off sequences.
