The MAX1202 EV system operates from a user-
supplied 9V to 15V DC power supply. The Maxim
68L11D 3V µC board uses a MAX667 linear regulator to
generate the 3V logic supply. The MAX1202 board
uses a 78L05 linear regulator to generate its own 5V
analog supply. No level translators are necessary
because the MAX1202 VL pin is connected to the 3V
logic supply.

only available serial port uses a 25-pin connector, a
standard 25-pin to 9-pin adapter is required. The EV

Quick Start
To evaluate the MAX1203, turn off the power to the EV kit,
close JU3, and replace U1 with a MAX1203BCPP.
Connect the external voltage reference to the VREF
pad. No other hardware changes are necessary. Refer
to the section Changing the Reference Voltage.
