MAX13335E Evaluation Kit
Evaluates: MAX13335E /MAX13336E
Software Startup
Upon starting the program, the EV kit software
automatically searches for the USB interface circuit and
then for the IC’s device address. The EV kit enters the
normal operating mode when the USB connection is
detected and has found the device address. If the USB
connection is not detected, the software prompts the
user to retry or enter the demo mode.
Demo Mode
The EV kit software enters demo mode when the USB
connection is not detected, or by selecting the Options
| Demo Mode menu item in the main window. When in
demo mode, all software communication to the EV kit
circuit is disabled; however, most of the software GUI is
functional. Demo mode allows the user to evaluate the
software without hardware connectivity.
Main Controls
The EV kit software’s Main Controls group box provides
checkboxes to control the IC’s Shutdown , Mute , Zero
Crossing Detection Enabled , Jack Sense Interrupt
Enabled , Clip Detected Interrupt Enabled , and Audio
Present Detected Interrupt Enabled features.
I 2 C Interface
The EV kit software’s Device Read/Write Addr radio
group box selects the device address to perform read or
write functions. The device’s I 2 C read and write addresses
are internally set to 0xD1 and 0xD0, respectively.
The I 2 C Register/Data group box contains the Register
Address to display the last register that was read from or
written to and the Data Sent , which displays the last data
that was sent or received.
Status
The Status group box displays the IC’s Die Revision ,
Thermal SHDN status, Jack Inserted status, Clip
Detected status, Audio Present status, and INT interrupt
output logic level.
Amplifier Gain
The Amplifier Gain group box provides the Right
Channel Amplifier Gain track bar/edit box and the Left
Channel Amplifier Gain track bar/edit box to configure
the IC’s amplifier output gain. The Track checkbox locks
the Right Channel Amplifier Gain track bar/edit box to
the Left Channel Amplifier Gain track bar/edit box when
it is checked. The IC’s amplifier gain range is between
-14dB and +16dB.
Diagnostic I/O Ports
The EV kit software Diagnostic I/O Ports group box
provides combo boxes to configure the IC’s diagnostic
I/O ports ( D0 – D3 ). Refer to the Detailed Description ,
Diagnostics , Applications Information , and Diagnostic
Configurations sections in the MAX13335E/MAX13336E
IC data sheet for additional details.
Write All/Read All/Reset
The Write All button writes the current settings to all the
registers on the GUI. The EV kit software GUI performs
I 2 C write commands as changes occur on the GUI. The
Read All button changes the GUI settings to match the
IC register settings. To change settings one time, enter
demo mode by selecting the Options | Demo Mode
menu item, change the GUI to the required settings, exit
demo mode by selecting Options | Demo Mode , and
then press the Write All button. To obtain the IC settings,
press the Read All button and the GUI is updated to
reflect the current register states of the IC. In addition,
the EV kit software can be set to automatically read
back the IC registers every two seconds by selecting
the Auto Read checkbox. The Reset button clears the
EV kit software GUI and reprograms the IC to the default
values.
Registers
The EV kit software Registers group box displays each
register’s individual bit logic-level status. A data bit in
bold indicates a logic-high, while a data bit that is not
bold indicates a logic-low. Clicking on the individual
data bit toggles the bit and performs a write command.
The new command is shown in the edit box at the
right. Alternatively, write commands can be written to
the registers by typing a hex value in the edit box and
pressing the Enter key on the keyboard.
Simple I 2 C Commands
There are three methods for communicating with the
EV kit, through the GUI components in the software
main window, the Registers group box in the main
window, or by using low-level SMBus commands
available in the Advanced User Interface window
(Figure 2). Select Options | Interface (Advanced Users)
to display the Advanced User Interface window that
allows I 2 C operations, such as SMBusReadByte and
SMBusWriteByte .
Detailed Description of Hardware
The MAX13335E EV kit evaluates the MAX13335E dual
automotive differential audio receivers with diagnostics
that communicate over I 2 C. The EV kit demonstrates
the IC’s features, such as user-defined amplifier gains,
interrupt enables, and diagnostic I/O configurations. The
EV kit uses the IC in a 16-pin QSOP package on a proven,
four-layer PCB design. The EV kit operates from a +3.3V
or +5V, 100mA DC power supply. The EV kit can also
operate from the on-board USB +5V available from a PC.
