AD22653B-2-Vrms Cap-Less Line Driver with Adjustable Gain DataSheet  

Description
    The AD22653B 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 AD22653B 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 AD22653B has built-in
active-mute control for pop-less audio on/off control.
    The AD22653B has internal and external under
voltage protection to prevent POP noise. Built-in
de-pop control sequence also help AD22653B to be
a pop-less device.
    The AD22653B is available in a 14-pin TSSOP
package.
