ESMT Features z z z z z z z z z z z Preliminary AD5265A 2.5W/CH Stereo Filter-less Class-D Audio Amplifier with Headphone Driver Description The AD5265A is a stereo, filter-less class-D audio amplifier with headphone driver. 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.
