Detailed Description of Hardware
The MAX5216 EV kit provides a proven layout for the
MAX5216 16-bit low-power, high-performance, buffered
DAC. An on-board reference (MAX6133), USB-PC con-
nection circuitry, and jumpers to disconnect the on-board
microcontroller are included on the EV kit.
Reference
The EV kit default configuration is with the reference
connected to VDD (see Table 1). To use the on-board
external 2.5V reference (MAX6133), move the shunt on
jumper JU6 to the 2-3 position and apply 2.7V to 12.6V
between the REF_SUP and GND PCB pads on the EV
kit. Optionally, the shunt on JU6 can be removed and an
external 2V to VDD reference applied at the REF loop on
the EV kit.
User-Supplied SPI Interface
and Power Supply
To use the EV kit with a user-supplied SPI interface, first
move the shunts on jumpers JU1–JU5 to the 2-3 posi-
tion. Next, apply a 2.7V to 5.25V power supply at the
EXT_VDD PCB pad on the EV kit. Lastly, connect the CS,
SCLK, DIN, CLR, and GND signals to the corresponding
pins of header H3.
