Описание
PAM8019 3W Stereo Class-D Audio Amplifiers
Diodes Inc. PAM8019 3W Stereo Class-D Audio Amplifiers are highly integrated power amplifiers for driving bridge-tied load (BTL) speakers. These amplifiers include Stereo Class AB amplifiers for driving headphones and are available in the power efficient and space saving package (U-QFN4040-20). The Auto Gain Control (AGC) function allows the PAM8019 amplifiers to maximize the output power while protecting the speakers. The 64 step DC volume control minimizes the external components and allows precise volume control over the range of +20dB to -60dB. The PAM8019 3W stereo Class-D audio amplifiers have mute and standby modes to disable the outputs and minimize the power consumption. These amplifiers are ideal for use in applications like LCD monitors/TVs, active/portable speakers, projectors, computing, and game machines.
