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 50O. 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 single 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.
