Description

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.
