General Description
The DS4420 is a fully differential, programmable-gain
amplifier for audio applications. It features a -35dB to
+25dB gain range controlled by an I2C interface and it
is optimized to drive loads as low as 50Ω. The gain is
adjustable in 3dB increments across the entire range.
Three address inputs, used to select the I2C slave
address, enable up to eight devices on a common bus.
The product operates from a single 5V supply over a
-20°C to +70°C temperature range. It is offered in a
3mm x 3mm TDFN package.
