The evaluation software’s main window shown in Figure
1 displays the voltage and code of the analog-input
signals AIN0–AIN7. The software supports manual read
or automatic read operations. Separate comboboxes
allow quick modifications to the MAX1168’s control
byte. The SPI™ serial clock frequency is adjustable
from 4.19MHz to 33kHz, and the software’s reference
value can be changed to match the applied external
reference. The provided Windows-compatible software
supports SPI mode (not DSP mode) and also only sup-
ports the MAX1168 EV kit when configured in 8-bit-wide
data-transfer mode. Table 1 describes all the controls
on the evaluation software’s main window.
The MAX1168 EV system is a complete 8-channel, 16-
bit data-acquisition system consisting of a MAX1168 EV
kit and a Maxim 68HC16MODULE-DIP µC module. The
MAX1168 EV system is used to evaluate the MAX1168
8-channel, 16-bit serial ADC. See the Quick Start sec-
tion for setup and operating instructions. See Table 1 for
more information on the provided Windows software.
