Data Logging
Start Convert
The Number of Samples drop-down list selects the
desired number of conversions. Press the Start
Convert button to start sampling at the rate set by the
Sample Rate edit box.
The on-board-generated convert start signal range is
from 1ksps to 130ksps. The external convert start signal
range is from 1ksps to 180ksps.
If using an external convert start signal, the GUI soft-
ware will measure and display the sample rate.
Output File Data
The Save to File button is not active until the sampling
is done. Press the Save to File button to save the sam-
pled data into a file.
Detailed Description of Hardware
MAX11046 EV Kit
The MAX11046 EV kit board provides a proven layout
for evaluating the MAX11046 8-channel, 16-bit, simulta-
neous-sampling ADC. The EV kit comes with the
MAX11046ETN+ installed. Eight BNC connectors are
provided on the EV kit for all input channels of the
MAX11046.
Power Supply
One DC power supply is required to power up the
MAX11046 EV kit. Connect the power supply (from 6V to
8V) between the VDD and the GND pads on the EV kit.
