MAX13335E/MAX13336E
Dual Automotive Differential Audio Receivers
with I2C Control and Diagnostics
General Description
Benefits and Features
● +3.3V or +5V Operation
The MAX13335E/MAX13336E are high-fidelity stereo
audio input amplifiers designed for automotive applica-
tions requiring audio-level detection and/or jack sensing
capability.
● +28V to -16V Tolerant Inputs
● Wide Common-Mode Input Range (-5V to +11.5V)
● 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 input signals with diagnostics capability
● Quasi-Differential Inputs Up to 3.5V
● Audio Presence Detection
● Jack Sense Detection
RMS

controlled through an I C interface. The devices’ audio
receiver can also pair with the MAX13325/MAX13326
audio transmitter to form a complete differential audio link
in automotive systems.
● Diagnostic Capability
● Programmable Gain with Zero-Crossing Detection
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 pro-
grammable gain amplifier is adjustable from -14dB to
+16dB (MAX13335E) and -22dB to +8dB (MAX13336E)
with zero-crossing detection to provide an optimum out-
put-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.

Thermal Shutdown
Detailed Description
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
The MAX13335E/MAX13336E are designed to operate
with the MAX13325/MAX13326 dual automotive audio
line drivers to form a complete differential audio link
in automotive systems. In addition, the MAX13335E/
MAX13336E can operate as an auxiliary input audio
amplifier with jack sense function.

until an I C read is performed.
Diagnostics
Signal Path
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 volt-
age sense, and a diode to ground.
The devices can be configured to operate with quasi-
differential (up to 3.5V
) and fully differential (up to
RMS
7V
) input signals. Both input channels feature high
RMS
80dB CMRR (typ). An integrated programmable gain
amplifier with zero-crossing detection controlled through
2
the I C 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 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
2
accessed by a microcontroller through the I C interface.
The procedure usually starts with stepping up the current
source from the minimum to maximum range.
Interrupt Output
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 I C interface to report the
presence of audio, clip detection, and change-of-state in
the jack sense. The internal status register also latches
1) If the sensed voltage is consistently below the low
threshold, a short-to-ground event is determined.
2
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 dif-
ferentiate 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-to-
battery event has occurred. Otherwise, an open-load
event is detected.

between the high and low thresholds, this could indi-

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 pro-
cedure 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.

STOP Conditions section). When the serial interface is
inactive, SDA and SCL idle high.
START and STOP Conditions
Applications Information
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
Serial Interface
Writing to the device using I C requires that first the mas-
2
ter send a START condition (S) followed by the device’s
2
I C 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 con-
dition (P) to relinquish control of the bus, or a repeated
START condition (Sr) to communicate to another I C
slave (Figure 2).
2
condition (S ) is generated instead of a STOP condition,
r
the bus remains active. When a STOP condition or incor-
rect 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.
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

reads the final byte of data from the device, followed by a
Acknowledge Bit
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 previ-
ous 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

can be programmed to operate in one of the four states:
1) Setting D_[3:0] = 0000 disables the corresponding diagnostic I/O.
2) Setting D_[3:0] = 0001 to 1101 enables the internal current source (40µA to 705µA) and voltage sensing. The volt-
age 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.

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.
source from D1 pulls D0 to V
resulting in DH0 = 1.
DD
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 con-
figured to detect faults in the wiring harness as shown in
the Typical Application Circuits.
Local Jack Sense
The device is configured for jack sense function when the
jack is localized to the same module. In this application

Audio Presence Detection
When the device is used in an auxiliary input ampli-
fier, 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:

2) Set API bit in the CTRL0 register to enable the APD
interrupt.
When the input audio level exceeds 200mV

the INT pin is asserted. The microcontroller can read back
the STAT0 register to check for APD = 1.

5) Enable the JSI bit in the CTRL0 register.
Low-Power Standby with Jack Sense
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:
When a plug is inserted, the DH0 comparator trips and
subsequently asserts the interrupt INT pin. The microcon-
troller can read back the STAT0 register to check for DH0
= 1 and follow up by setting SHDN to 0.
1) Connect D0 to the R (or L) of the jack.
In the standby state, the typical current consumption is
reduced to 290µA.
2) Connect R
(or L
) of the jack with a 50Ω
SENSE
SENSE
resistor to ground.
3) Set the SHDN bit to 1 in the CTRL0 register to power
down the amplifier.

on application requirements, the IC side may allow for a
ESD Guide
For maximum protection against IEC 61000-4-2 and
ISO 10605 ESD pulses, a 1kΩ or larger resistor is rec-
ommended on every diagnostic D_ pin before the input
AC-coupling capacitor. Additionally, a suitable ESD diode
must be connected from the DC-blocking ceramic capaci-
tor to ground. The ESD diode can be connected on either
lower clamping voltage, which results in a smaller ESD
device. If the input source is always DC biased to V /2,
BAT
then a unidirectional ESD device can be used when
clamping on the input side of the DC-blocking capacitor.
