EVALUATION KIT AVAILABLE MAX13335E/MAX13336E Dual Automotive Differential Audio Receivers 2 with I C Control and Diagnostics General Description Benefits and Features The MAX13335E/MAX13336E are high-fidelity stereo +3.3V or +5V Operation audio input amplifiers designed for automotive applica- +28V to -16V Tolerant Inputs tions requiring audio-level detection and/or jack sensing Wide Common-Mode Input Range (-5V to +11.5V) capability. Fully Differential Inputs Up to 7V RMS The devices feature a dual-channel, low-noise, program- mable gain amplifier that accepts fully differential and Quasi-Differential Inputs Up to 3.5V RMS quasi-differential input signals with diagnostics capability Audio Presence Detection 2 controlled through an I C interface. The devices audio Jack Sense Detection receiver can also pair with the MAX13325/MAX13326 Diagnostic Capability audio transmitter to form a complete differential audio link in automotive systems. Programmable Gain with Zero-Crossing Detection Each channel of the device features high common-mode 2 I C Control Interface rejection ratio (CMRR) (80dB), enabling the recovery of Automotive Grade ESD Protection audio signals in the presence of large common-mode ISO 10605 15kV Air Gap noise in automotive environments. An integrated pro- 8kV Contact Discharge grammable gain amplifier is adjustable from -14dB to +16dB (MAX13335E) and -22dB to +8dB (MAX13336E) Applications with zero-crossing detection to provide an optimum out- Radio Head Units put-signal level and limit zip noise. The external flexible RSA/RSE diagnostic inputs can be configured to perform jack sense Connectivity Modules functions or to detect short-to-battery, short-to-ground, Automotive Telematics 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 -40C to +105C operating temperature Ordering Information appears at end of data sheet. range, and are available in a 16-pin QSOP package.
