MAX11300 Evaluation Kit
Detailed Description of Hardware
The MAX11300 EV kit uses an on-board MAXQ2000
microcontroller (U120) to send SPI commands to the
device. On-board level translators (U101, U102, and
U105) convert from 3.3V to 5V levels. On-board MAX6071
voltage references (U3, U6) provide ADC and DAC
reference voltages. Remote temperature sensing can be
simulated by on-board 3904 npn transistors (D0, D1). See
Figure 7.
Connecting to User-Supplied Circuitry
The EV kit connects to external, user-supplied circuitry
through header J1 or J2. These two headers have the
same signals; J1 is for vertical 50-pin ribbon-cable con-
nection and J2 is for right-angle connection to a sideboard
by standard 0.100in right-angle pins.
If remote temperature sensing is used, disconnect on-
board npn transistors D0 and D1 by moving the shunts of
JUD0P, JUD0N, JUD1P, and J1D1N to the 1-4 position.
