Product Details
The MAX13335E/MAX13336E are high-fidelity stereo audio input amplifiers designed for automotive applications requiring audio-level detection and/or jack sensing capability.
The devices feature a dual-channel, low-noise, programmable gain amplifier that accepts fully differential and quasi-differential input signals with diagnostics capability controlled through an I²C interface. The devices' audio receiver can also pair with the MAX13325/MAX13326 audio transmitter to form a complete differential audio link in automotive systems.
Each channel of the device features high common-mode rejection ratio (CMRR) (80dB), enabling the recovery of audio signals in the presence of large common-mode noise in automotive environments. An integrated programmable gain amplifier is adjustable from -14dB to +16dB (MAX13335E) and -22dB to +8dB (MAX13336E) with zero-crossing detection to provide an optimum output-signal level and limit zip noise. The external flexible diagnostic inputs can be configured to perform jack sense functions or to detect short-to-battery, short-to-ground, open load, and shorts between channels.
The audio inputs are protected against ISO 10605 ±15kV Air Gap and ±8kV Contact Discharge ESD pulses. Both devices have a -40°C to +105°C operating temperature range, and are available in a 16-pin QSOP package.
