MAXADClite Evaluation Kit
The MAXADClite EV kit board is a plug-n-play data-
acquisition kit that connects to the PC through a USB
cable. The EV kit digitizes two different analog inputs
and does not require an external power supply or a
USB device driver. The EV kit is preloaded with default
firmware that communicates with the MAXADClite evalu-
ation software. Software can be installed and run on any
Windows-based system.
Note: In the following sections, software-related items
are identified by bolding. Text in bold refers to items
directly from the EV kit software. Text in bold and under-
lined refers to items from the Windows operating system.
The EV kit is fully assembled and tested. Follow the steps
below to acquire data through the EV kit:
1)
2) Connect the analog input(s) at AIN0 or AIN1 and
3) Install and run the MAXADClite GUI application.
4) Once the status bar displays Hardware connected,

The MAXADClite EV kit board is loaded with the
MAX11645, Maxim’s smallest, lowest power, 12-bit ADC.
The ADC communicates through an I
16-bit RISC MAXQ622 microcontroller with integrated
USB serial interface engine (SIE). This microcontroller
can be configured as an HID device to communicate
witht eh PC over USB (Figure 2).
The EV kit microcontroller is preloaded with firmware
that communicates with the EV kit GUI application. Upon
receiving the logging command from the GUI, it acquires
data from the ADC over the I
PC for display and further analysis.
