PAM8301AAF

PAM8301AAF is a 1.5W Class-D mono audio amplifier. Its low THD+N feature offers high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly instead of using low-pass output filters, therefore saving system cost and PCB area. With the same number of external components, the efficiency of the PAM8301 is much better than that of Class-AB cousins. It can optimize battery life, thus, it is ideal for portable applications. Applications include PMP/MP4, GPS, portable speakers, walkie-talkie, handsfree phones/speaker phones, cellular phones.

• 1.5W output at 10% THD with a 8ohm load and 5V power supply
• Filterless, low quiescent current and low EMI
• Superior low noise, short circuit protection, thermal shutdown
• Few external components to save space and cost
• 2.5 to 5.5V supply voltage range
• Quiescent current is 4mA typ at no load, TA = +25°C, VDD = 5V, gain = 24dB, RL = 8ohm
• Total harmonic distortion plus noise is 0.2% typ at RL = 8ohm, PO = 200mW, TA = 25°C
• Signal to noise ratio is 78dB typ at f = 20 to 20kHz, TA = +25°C, VDD = 5V, gain = 24dB, RL = 8ohm
• SOT23-6 package
• Operation temperature range from -40 to +85°C
