Description
The AD52660A is a high efficiency stereo Class-D audio amplifier. Operating with 8~15V supply, it can deliver 12W/CH output power into 8 Ω loudspeaker
within 1% THD+N.
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 (7x7mm) is a stereo audio amplifier with high efficiency and low thermal resistance which leads to no external heat sink requirement under 10W/ch output power.
