EVALUATION KIT AVAILABLE MAX13335E/MAX13336E Dual Automotive Differential Audio Receivers with I2C Control and Diagnostics General Description The MAX13335E/MAX13336E are high-fidelity stereo audio input amplifiers designed for automotive applications requiring audio-level detection and/or jack sensing capability. Benefits and Features ●● +3.3V or +5V Operation ●● +28V to -16V Tolerant Inputs ●● Wide Common-Mode Input Range (-5V to +11.5V) 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. ●● Fully Differential Inputs Up to 7VRMS 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. ●● I2C Control Interface 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. ●● Quasi-Differential Inputs Up to 3.5VRMS ●● Audio Presence Detection ●● Jack Sense Detection ●● Diagnostic Capability ●● Programmable Gain with Zero-Crossing Detection ●● Automotive Grade ESD Protection • ISO 10605 ±15kV Air Gap • ±8kV Contact Discharge Applications ●● ●● ●● ●● Radio Head Units RSA/RSE Connectivity Modules Automotive Telematics Ordering Information appears at end of data sheet.

In addition, the MAX13335E/ MAX13336E can operate as an auxiliary input audio amplifier with jack sense function. Thermal shutdown protects the device when the junction temperature exceeds +150°C (typ). The device resumes operation when the junction temperature drops below the thermal shutdown hysteresis of 15°C (typ). The internal status register latches the status change of the TSD bit until an I2C read is performed. Diagnostics Signal Path The devices can be configured to operate with quasidifferential (up to 3.5VRMS) and fully differential (up to 7VRMS) input signals. Both input channels feature high 80dB CMRR (typ). An integrated programmable gain amplifier with zero-crossing detection controlled through the I2C interface provides adjustable gain from -14dB to +16dB (MAX13335E) or -22dB to +8dB (MAX13336E) in +2dB increments. Zero-crossing detection can be enabled to limit the zip noise during a gain transition by delaying the gain change until a zero-crossing event occurs on the input signal. The devices feature four similar diagnostic I/O ports. When configured correctly, they are capable of performing jack sense detection, short-to-ground, short-to-battery, open-load, and shorts between channels. Each diagnostic I/O port contains a programmable current source, a voltage sense, and a diode to ground. Interrupt Output The procedure usually starts with stepping up the current source from the minimum to maximum range. The devices can monitor the inputs for the presence of audio, clip detection, and change-of-state in the jack sense. An active-low, open-drain interrupt request output can be configured through the I2C interface to report the presence of audio, clip detection, and change-of-state in the jack sense. The internal status register also latches the status change of those parameters until an I2C read is performed. 40µA TO 705µA D_ RD_ VIDH DH_ DL_ VIDL Figure 1. Diagnostic I/O Port www.maximintegrated.com I2C INTERFACE The principle behind the diagnosis is simply forcing a current into the load attached to the I/O port and sensing the voltage to check if it is greater or smaller than the two predefined low/high thresholds. These can be easily accessed by a microcontroller through the I2C interface. 1) If the sensed voltage is consistently below the low threshold, a short-to-ground event is determined. 2) However, if the sensed voltage is consistently above the high threshold, there is a possibility of either a short-to-battery or an open-load event. In order to differentiate between them, the I/O port should be tested again with a voltage-sense-only configuration (i.e., with the current source switched off). If the sensed voltage remains above the high threshold, a short-tobattery event has occurred. Otherwise, an open-load event is detected. 3) In some current source range, if the sensed voltage is between the high and low thresholds, this could indicate that the load is present. A valid readout of the status might require some amount of delays (to be inserted by the microcontroller) due to the settling time needed to charge/discharge any external capacitive load on the I/O port. The diode is useful in the case of sensing an unconnected load or short between channels. Here, one end of the load can be forced to ground by the diode and the usual procedure described above can be applied to detect various events. It is, however, advisable to test the I/O port for a short-to-battery condition prior to turning on the diode as it could risk damaging the device.

When the serial interface is inactive, SDA and SCL idle high. Applications Information START and STOP Conditions Serial Interface Writing to the device using I2C requires that first the master send a START condition (S) followed by the device’s I2C address. After the address, the master sends the address of the register that is to be programmed. The master then ends communication by issuing a STOP condition (P) to relinquish control of the bus, or a repeated START condition (Sr) to communicate to another I2C slave (Figure 2). Bit Transfer Each SCL rising edge transfers one data bit. The data on SDA must remain stable during the high portion of the SCL clock pulse (Figure 3). Changes in SDA while SCL A master device initiates communication by issuing a START condition (S) which is a high-to-low transition on SDA with SCL high. A START condition from the master signals the beginning of a transmission to the device. The master terminates transmission by a STOP condition (P) (see the Acknowledge Bit section). A STOP condition is a low-to-high transition on SDA while SCL is high (Figure 4). The STOP condition frees the bus. If a repeated START condition (Sr) is generated instead of a STOP condition, the bus remains active. When a STOP condition or incorrect slave ID is detected, the device internally disconnects SCL from the serial interface until the next START or repeated START condition, minimizing digital noise and feedthrough.

START/STOP Conditions Maxim Integrated │  12 MAX13335E/MAX13336E Dual Automotive Differential Audio Receivers with I2C Control and Diagnostics Acknowledge Bit reads the final byte of data from the device, followed by a STOP condition. The acknowledge bit (ACK) is a clocked 9th bit that the device uses to handshake the receipt of each byte of data when in write mode. The device pulls down SDA during the entire master-generated 9th clock pulse if the previous byte is successfully received (Figure 5). Monitoring ACK allows for detection of unsuccessful data transfers. An unsuccessful data transfer occurs if a receiving device is busy or if a system fault has occurred. In the event of an unsuccessful data transfer, the bus master could retry communication. The master must pull down SDA during the 9th clock cycle to acknowledge receipt of data when the device is in read mode. An acknowledge must be sent by the master after each read byte to allow data transfer to continue. A not-acknowledge is sent when the master Slave Address The device is programmable to one of the four I2C slave addresses (Table 2). The power-on default I2C slave address of the device for read/write is 0xD0/0xD1 (1101000R/W). The I2C slave address of the device can be selected by writing to Control Register 1 (0x03) while INT is pulled low externally during the I2C write duration (Figure 6). Single Byte-Write Operation For a single byte-write operation, send the slave address as the first byte followed by the register address and then a single data byte (Figure 7).

The voltage sensing utilizes a window comparator with an upper threshold of 1.94V and a lower threshold of 0.92V (see the Diagnostic Configurations section). 3) Setting D_[3:0] = 1110 enables voltage sensing only. 4) Setting D_[3:0] = 1111 enables the internal diode to ground.

The gain of the programmable gain amplifier (AV) is determined by the following transfer function: Gain(AV) = -14dB + (G_[3:0] x 2)dB (for MAX13335E) Gain(AV) = -22dB + (G_[3:0] x 2)dB (for MAX13336E) Diagnostic Configurations The device’s diagnostics can be configured for local jack sense, remote jack sense, and differential drive connections (see the Typical Application Circuits). Diagnostic registers DIAG0 and DIAG1 configure the diagnostic I/O ports D_ as a current-source output with voltage sensing enabled, a voltage sensing input, or a diode to GND. When voltage sensing is enabled, the current states of the internal window comparator are updated to status register STAT0. A valid readout of the STAT0 register might require some amount of delays (to be inserted by the microcontroller) between configuring the diagnostic and reading the status register due to the settling time needed to charge/discharge the external capacitive load on the D_ pins. Local Jack Sense The device is configured for jack sense function when the jack is localized to the same module. In this application example, the diagnostic I/O D1 is configured as a 97µA current-source output and D0 is configured for voltage sensing. When a plug is not inserted, the internal spring contact of the jack shorts D1 to D0. The 97µA current source from D1 pulls D0 to VDD resulting in DH0 = 1. When a plug is inserted, the internal spring contact of the jack is forced open and disconnects D1 from D0. This results in D0 going low and hence DH0 = 0. Remote Jack Sense Detection When the jack is remotely located, the device can be used for additional fault detection of the wiring harness used for the connection. See the Typical Application Circuits. Differential Connection For fully differential applications, the device can be configured to detect faults in the wiring harness as shown in the Typical Application Circuits. Table 4.

Diagnostic Setup for Local Jack Sense Audio Presence Detection When the device is used in an auxiliary input amplifier, it can detect if audio is present at the inputs so the downstream DSP does not have to continuously convert the analog signal to digital in order to monitor the audio stream. This can save two ADC inputs as the auxiliary input can be muxed with another audio stream that is mutually exclusive. To do this, perform the following steps: www.maximintegrated.com 1) Set the gain in the GAIN register based on the required input audio level where the APD threshold is exceeded. The threshold is set to 200mVRMS/G_[3:0]. 2) Set API bit in the CTRL0 register to enable the APD interrupt. When the input audio level exceeds 200mVRMS/G_[3:0] the INT pin is asserted. The microcontroller can read back the STAT0 register to check for APD = 1.

Diagnostic Setup for Remote Jack Sense Low-Power Standby with Jack Sense 4) Set D0[3:0] = 0001 to source 40µA out of the D0 pin. 1) Connect D0 to the R (or L) of the jack. When a plug is inserted, the DH0 comparator trips and subsequently asserts the interrupt INT pin. The microcontroller can read back the STAT0 register to check for DH0 = 1 and follow up by setting SHDN to 0. 2) Connect RSENSE (or LSENSE) of the jack with a 50Ω resistor to ground. In the standby state, the typical current consumption is reduced to 290µA. When the device is used as an auxiliary amplifier, there is the option to put the device into a low-power standby mode while waiting for a plug to be inserted into the jack. To do this, perform the following steps: 5) Enable the JSI bit in the CTRL0 register. 3) Set the SHDN bit to 1 in the CTRL0 register to power down the amplifier. www.maximintegrated.com Maxim Integrated │  22 MAX13335E/MAX13336E Dual Automotive Differential Audio Receivers with I2C Control and Diagnostics ESD Guide For maximum protection against IEC 61000-4-2 and ISO 10605 ESD pulses, a 1kΩ or larger resistor is recommended on every diagnostic D_ pin before the input AC-coupling capacitor. Additionally, a suitable ESD diode must be connected from the DC-blocking ceramic capacitor to ground. The ESD diode can be connected on either side of the DC-blocking capacitor; however, depending on application requirements, the IC side may allow for a lower clamping voltage, which results in a smaller ESD device. If the input source is always DC biased to VBAT/2, then a unidirectional ESD device can be used when clamping on the input side of the DC-blocking capacitor.
