Evaluates: MAX541/MAX542
In the main window of the evaluation software (Figure 1),
the user can type in the reference voltage in the REF
Voltage edit box. The software then calculates the DAC
output voltages based on the reference voltage and the
DAC input register value.
The MAX541 group box controls the MAX541 unipolar
DAC on the EV kit board. The MAX542 group box controls
the MAX542 bipolar DAC on the EV kit board.
To change the DAC input register value, type in the
desired value in the DIN Register edit box and press
the Enter button. The user can also move the track bar
to change the DAC input register value. The DIN code
and the target DAC output voltages are displayed for
verification.
Selecting the LDAC High radio button in the MAX542
group box sets the MAX542 /LDAC pin high; selecting
the LDAC Low radio button sets the MAX542 LDAC pin
low. When the LDAC Low radio button is selected, the
output of the DAC updates immediately when the DAC
input register is updated. Pressing the LDAC Pulse but-
ton generates a low pulse on the MAX542 LDAC pin and
updates the output of the DAC.
For the MAX542, the target output voltages are calculated
based on the selected mode in the Output Mode radio
group box.
Click on the Connect menu item to connect the board to
the software if the USB connection is lost.
The MAX54X EV kit provides a proven design to evaluate
the installed MAX541/MAX542 serial-input, voltage-output,
16-bit DACs. The DACs are controlled by an on-board
MAXQ microcontroller that provides two separate SPI
control interfaces.
The EV kit provides on-board +2.5V high-precision volt-
age references. Use jumper JU2 to select from different
reference sources.
The EV kit connects one precision bipolar buffer
(MAX9632) to the MAX542 and one ultra-precision uni-
polar buffer (MAX44251) to the MAX541.
