Functional Block Diagram
Description
The AD52660A is a high efficiency stereo class-D
audio amplifier. Operating with 8 ~ 12V supply, it can
deliver 9.5W/CH output power into 8 Ω loudspeaker
within 10% THD+N and without external heat sink.
The AD52660A has two volume control modes by
setting MODE0 pin. While MODE0 pin is set logic
high, AD52660A is in DC volume control mode with
31-step volume gain, adjusted by the DC voltage
applied on GAIN0 pin. Otherwise, AD52660A is the
4-step volume gain mode, selected by setting
GAIN0 and GAIN1 pins. The two volume adjustment
modes are designed to fit the different volume
control requirements in various applications.
The AD52660A packaged as E-LQFP 48L is a
stereo audio amplifier with high efficiency and low
thermal resistance which leads to no external heat
sink requirement under 9.5W/ch output power.
