Diodes Inc. has announced a 20W mono Class-D audio amplifier in the space-saving SOP16 exposed-pad, surface-mount package. According to the firm, the PAM8320's low-impedance drive capability allows it to deliver 20W into a 4 bridge-tied-load speaker.

The company stated that the device is intended for a variety of high-power, small-enclosure speakers in wireless headphones, PCs and docking station products. The amplifier's 4.5-15V supply range also means it performs equally well for battery cell and mains-driven consumer audio systems, continued Diodes.

Operating at an efficiency of up 95 per cent, the PAM8320 eliminates the need for an external heatsink, saving system space and reducing BOM cost. To help increase product reliability, the 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.
