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.
