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.
