描述 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.
