PAM8019KGR, Усилитель звуковой мощности, 3 Вт, D, AB, 2 канала, 2.8В до 5.5В, U-QFN4040, 20 вывод(-ов)

Полупроводники - Микросхемы\Усилители и Компараторы\Аудио УсилителиPAM8019KGR is a 3W stereo class-D audio amplifier and class AB headphone driver with DC volume control, non-clip power limit and UVP. This stereo 3W Class D audio power amplifier for driving bridged-tied speakers and includes a Stereo Class AB amplifier for driving headphones. Integrated non-clip power limit technology suppresses output automatically with programmable power limit, improving the sound quality and helping to protect the speakers. Programmable under voltage protection (UVP) can be used to shut down the PAM8019 at a pre-determined voltage level helping to eliminate speaker pop by shutting down before the power supply collapses. Applications include LCD monitors and TVs, projectors / all-in-one computers, portable / active speakers, portable DVD players / game machines. • Filter free and low EMI architecture• Supply voltage range from 2.8 to 5.5V (TA = +25°C, VDD = 5V, Gain = Max., RL=8ohm)• Low quiescent current of 7mA at a VDD of 5V• 64 step DC volume control with hysteresis from -60dB to +20dB• Class D amplifier THD+N=1%, VDD=5V, load =4ohm, Po=2.4W / Load =8ohm, Po=1.4W• Class D amplifier THD+N=10%, VDD=5V, load =4ohm, Po=3.0W / load =8ohm, Po=1.7W• Class AB headphone amplifier, VDD=5V, load=32ohm, Po=60mW• Non clip power limit (NCPL) function, OVP and programmable UVP protection• Thermal and over-current protection with auto-recovery• 20 lead U-QFN4040 package, ambient operation temperature range from -40 to +85°C
