Figure 1. MAX544X Evaluation Kit Software (Main Window)
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 MAX5441 group box controls the MAX5441 unipolar
DAC on the EV kit board. The MAX5442 group box con-
trols the MAX5442 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.

Evaluates: MAX5441–MAX5444
Selecting the CLR High radio button in the MAX5441
group box sets the MAX5441 CLR pin high; selecting the
CLR Low radio button sets the MAX5441 CLR pin low.
Pressing the CLR Pulse button generates a low pulse
on the MAX5441 CLR pin and clears the DAC buffer to
code 0.
Selecting the CLR High radio button in the MAX5442
group box sets the MAX5442 CLR pin high; selecting the
CLR Low radio button sets the MAX5442 CLR pin low.
Pressing the CLR Pulse button generates a low pulse on
the MAX5442 CLR pin and clears the DAC buffer to code
0x8000 (32768).
For the MAX5442, the target output voltages are calcu-
lated based on the mode of the output buffer circuit.
Click on the Connect menu item to connect the board to
the software if the USB connection is lost.
