The MAX13335EGEE/V+ from Maxim Integrated Products is a dual automotive differential audio receivers with I2C control and diagnostics in 16 pin QSOP package. It is a high -fidelity stereo audio input amplifier designed for automotive applications requiring audio-level detection and/or jack sensing capability. It features 2-ch, low noise, programmable gain amplifier that accepts fully differential and quasi differential input signals with diagnostics capability controlled through an I2C interface. The device"s audio receiver can also pair with MAX13325 audio transmitter to form a complete differential audio link in automotive systems. Each channel features high 80dB CMRR enabling recovery of audio signals in presence of large common mode noise in automotive environments. Typical applications are radio head units, RSA/RSE, connectivity modules and automotive telematics.
