DS4420 - Maxim Integrated Products

DS4420 I2C Programmable Gain Amplifier

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 I 2 C slave address, enable up to eight devi.
