The PAM8100 is a 3-VRMS pop-free stereo line driver designed toallow the removal of the output DC-blocking capacitors for reducedcomponent count and cost. The device is ideal for single-supplyelectronics where size and cost are critical design parameters.The PAM8100 is capable of driving 3Vrms into a 2.5-kΩ load with 5-Vsupply voltage. The device has differential inputs and uses externalgain-setting resistors to support a gain range of ±1 V/V to ±10 V/V.The PAM8100 has built-in mute control for pop-free on/off control.The PAM8100 has an external and internal undervoltage detector thatmutes the output.Using the PAM8100 in audio products can reduce component countconsiderably compared to traditional methods of generating a 3-Vrmsoutput.The PAM8100 is available in a 14-pin TSSOP.

The PAM8106 is a 10W / ch stereo class-D audio amplifier with Spread-Spectrum modulation, which offers high-quality low THD+N, low EMI, and high PSRR

The PAM8302L is a 2.5W Class-D mono audio amplifier. Its low THD+N offers high-quality sound reproduction. The PAM8302L uses a filterless design that avoids the use of lowpass filters. This new design allows the amplifier to directly drive a speaker, making it cheap and compact. The new design allows the amplifier to be more affordable and take less PCB area. The PAM8302L uses less power than the Class-AB amplifiers. The use of this product can help optimize battery life; it is ideal for portable applications. The PAM8302L is available in MSOP-8 and DFN3x3-8 packages.

The PAM8303C is a 3W mono filterless Class-D amplifier with high PSRR and differential input that eliminate noise and RF rectification. Features like 90% efficiency and small PCB area make the PAM8303C Class-D amplifier ideal for cellular handsets. The filterless architecture requires no external output filter, fewer external components, less PCB area and lower system costs, and simplifies application design. The PAM8303C features short circuit protection and thermal shutdown. The PAM8303C is available in 9-ball WCSP, MSOP-8 and DFN 3x3 8-pin packages.

The PAM8304 is a mono, filter-less, Class-D amplifier with high SNR (signal-to-noise ratio) and differential input that helps eliminate noise. The PAM8304 supports 2.8V to 6V operation, which makes it ideal for up to 4-cell alkaline battery applications. The PAM8304 is capable of driving speaker loads as low as 3Ω with a 5V supply, maximizing the output power.

The PAM8320 is an efficient 20W mono Class-D audio poweramplifier, designed to drive speakers as low as 4Ω in a bridge-tiedloadconfiguration. Due to the low power dissipation and highefficiency of up to 95%, the device can be used without any externalheat sink whilst playing music.The PAM8320 features short circuit protection, thermal shutdown,over voltage protection and under voltage lock-out.The PAM8320 is available in a SO-16EP package.
