Description
The AD52651A is a stereo, filter-less class-D
with 5.0V loudspeaker driver supply, it can deliver
2.5W/CH output power into 4
Ω
loudspeaker within
10% THD+N and 120mW/CH output power into 16
Ω
headphone within 1% THD+N.
The AD52651A has two volume control modes by
setting MODE pin. While MODE pin is set logic high,
AD52651A 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,
AD52651A 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. Beside
stereo class-D amplifier, AD52651 has built-in an
inverted stereo class-AB headphone driver. With the
independent power-down control for left or right
channel, the AD52651 is more convenient to control
the left and right channels.
The AD52651A packaged as E-TSSOP 24L is a
stereo audio amplifier with high efficiency, which
leads to longer battery left, less heat sink
requirement, smaller board size and lower system
cost, and suitable for the notebook computer, and
portable multimedia devices.
