Description
    The AD22653 is a 2-Vrms cap-less stereo line driver. The device is ideal for single supply electronics. Cap-less design can eliminate output dc-blocking capacitors for better low frequency response and save cost.
    The AD22653 is capable of delivering 2-Vrms output into a 10kΩ　load with 3.3V supply. The gain settings can be set by users from ±1V/V to ±10V/V externally, and gain can be configured individually for R/L channel. The AD22653 has built-in active-mute control for pop-less audio on/off control.
    The AD22653 has internal and external under voltage protection to prevent POP noise. Built-in de-pop control sequence also help AD22653 to be a
pop-less device. The AD22653 is available in a 14-pin TSSOP package.
