Description
The AD52650 is a stereo, filter-less class-D audio
amplifier. Operating with 5.0V loudspeaker driver
supply, it can deliver 2.5W/CH output power into 4 Ω
loudspeaker within 10% THD+N.
The AD52650 has two volume control modes by
setting MODE pin. While MODE pin is set logic high,
AD52650 is in DC volume control mode with 31-step
volume gain from -38 dB to +20dB, adjusted by the
DC voltage applied on G0 pin. Otherwise, AD52650
is the 4-step volume gain mode with +6dB, +12dB,
+18dB, and +24dB gain, selected by setting G0 and
G1 pins. The two volume adjustment modes are
designed to fit the different volume control
requirements in various applications.
The AD52650 packaged as E-TSSOP 24L is a
stereo audio amplifier with high efficiency, which
leads to longer battery life, less heat sink
requirement, smaller board size and lower system
cost, and suitable for the notebook computer, and
portable multimedia devices. With the independent
shut-down control for left or right channel, the
AD52650 is more convenient to control the left and
right channels.
