rate at which data is being sampled by the ADC and
stored in the µC’s memory. Use the pulldown menu to
select the desired SCLK frequency. The first two digits
are the divisor for the µC’s internal clock. The next float-
ing point number is the corresponding SCLK frequen-
cy. The ADC to µC sample rate is displayed in the ADC
to µC sample rate field located on the right side of the
main window.
The µC to PC transfer rate is controlled using the field
at the bottom of the main window and can be controlled
in two different ways. Pressing the Read button allows
the user to manually grab a sample from the µC’s mem-
ory. Clicking the Read Every checkbox allows the user
to automatically read samples from the µC’s memory at
a rate selectable in milliseconds.
To retrieve a block of consecutively sampled data to
the PC, click on the Sample menu located at the top
left-hand corner of the main window. The data-block
length is selectable and the data can be saved to a file.
The Minimum and Maximum fields in the statistics area
show the highest and lowest readings acquired. The
Average field displays a running mean. When reading
data manually by pressing the Read button, the Average
and RMS fields require approximately five samples until
they are accurately represented. The Clear Statistics
button resets the statistics. To remove offset errors, first
apply zero volts to the active input channel, press the
Clear Statistics button, acquire some samples, and then
check the Null Offset checkbox. Once checked, the
label next to the Null Offset checkbox shows the sam-
pled offset error. This value is subtracted from all subse-
quent measurements until the checkbox is unchecked.

Statistics
The EV software assumes a 4.096V reference voltage,
unless otherwise specified. To override the 4.096V ref-
erence value, apply the new reference voltage at the
terminal block (TB0) on the MAX1162 EV kit board, type
in the new reference voltage, without the volt unit, and
press the Set Vref button. The EV kit software uses the
value typed in the V
code to a voltage.
The MAX1162 is a 16-bit serial ADC. When the
MAX1162 EV kit board is connected to the
68HC16MODULE-DIP module, power is provided to U2
by the module. The user must also provide 5V to VDD
and -5V to VEE (with respect to the GND pads) on the
MAX1162 EV kit board. The MAX1162 EV kit contains
two different types of buffers. U2 is a logic buffer to limit
the load capacitance that is seen by the DOUT line of
the MAX1162. U1 is powered from VDD. U3 is powered
from VDD and VEE. A terminal block (TB0) has also
been provided on the MAX1162 EV kit board for the
external reference. See the Reference Voltage section
and the MAX1162 EV Kit Schematic (Figure 2).
