DS4420N+

The DS4420N+ is an I2C programmable-gain amplifier for audio applications in 14 pin TDFN package. This fully differential amplifier features a -35dB to +25dB gain range controlled by an I2C interface and it is optimized to drive loads as low as 50 ohm. The gain is adjustable in 3dB increments across the entire range. It is used in telephone headsets, microphone gain control and audio volume control.
