MAX110 Evaluation System/Evaluation Kit
_______________________________________________________________________________________
The MAX110 EV kit supports both the MAX110 and the
MAX111 ICs. To evaluate the MAX111 use the following
procedure:
1) While the EV kit is turned off, move J4 to the 2-3
2) Replace U1 with a MAX111.
3) Note that the MAX111 uses a 1.25V reference.
4) Follow the quick-start instructions for the MAX110.
The MAX111 output codes are identical to the MAX110
output codes. The input voltage range is more restricted
on the MAX111 because it is a single-supply device. Refer
to the MAX110/MAX111 data sheet for more information
on the MAX111’s input voltage range and accuracy.
For the MAX111, tie the V
the J4 shunt between pins 2 and 3. For the MAX110, tie
the V
pins 1 and 2.
Several jumper blocks allow different configurations of
the MAX110. Jumper functions and default settings are
shown in Tables 1 and 2.
To drive the MAX110 with an external clock, use the
following procedure:
1) Put a shunt across J5 pins 2-3, leaving pin 1 open.
2) Put a shunt across J1 pins 1-2, leaving pin 3 open.
3) Connect the external oscillator to the EXTCLK pad.
4) Connect the oscillator ground to the GND pin of
