The AD22650 is a 3-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 AD22650 is capable of delivering 3-Vrms output into a 2.5kΩ load with 5V supply. The gain settings can be set by users from 1V/V to 10V/V externally. The AD22650 has internal and external under voltage protection to prevent POP noise.
Build-in shutdown control and de-pop control sequence also help AD22650 to be a pop-less device.
The AD22650 is available in a 14-pin TSSOP package.
