Operating 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 16Ω headphone within 1% THD+N. The AD5265A has two volume control modes by setting MODE pin. While MODE pin is set logic high, AD5265A 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, AD5265A 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. Not only the stereo class-D amplifier, AD5265A also has a fixed gain (-1V/V) stereo class-AB headphone driver. The AD5265A 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 AD5265A is more convenient to control the left and right channels. Supply voltage range: 2.5 V to 5.5 V Support single-ended or differential analog input Low static operat...
