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.ApplicationsAutomotive TelematicsConnectivity ModulesRadio Head UnitsRSA/RSE

The MAX13342E/MAX13345E USB-compliant transceivers are designed to minimize the area and external components required to interface low-voltage ASICs to USB. The devices comply with USB 2.0 specification for full-speed-only (12Mbps) operation. The transceivers include an internal 3.3V regulator, an internal 1.5kΩ D+ pullup resistor, and built-in ±15kV ESD protection circuitry to protect the USB I/O ports (D+, D-). The MAX13345E also has internal series resistors, allowing these components to be wired directly to a USB connector.These devices operate with logic-supply voltages as low as +2.3V, ensuring compatibility with low-voltage ASICs. A low power mode reduces current consumption to less than 45µA. An enumerate function allow devices to logically disconnect while remaining plugged in.The MAX13342E has controlled output impedance of 2Ω (max) on D+/D-, allowing the use of external switches to multiplex two different USB devices onto a single USB connector. The MAX13345E had 43.5Ω (max) internal resistors on D+/D- for direct connection to the USB connector.The MAX13342E/MAX13345E are equipped with DAT and SE0 interface signals. These transceivers provide a USB detection function that monitors the presence of USB VBUSand signals the event.These devices operate over the extended -40°C to +85°C temperature range and are available in UCSP™ 2.0mm x 1.5mm and 14-pin TDFN (3mm x 3mm) packages.ApplicationsCellular TelephonesData CradlesMP3 PlayersPC PeripheralsPDAs
