The MAX1236 is a four-channel (two differential-chan-
nel) 12-bit ADC with a 2-wire serial interface. The open-
collector inverter (U2) interfaces the PC parallel port to
the 2-wire serial interface. U2 and the associated cir-
cuitry are only required when interfacing to the parallel
port. Power the MAX1236 EV kit from a 5VDC power
supply. To prevent damage to the MAX1236 EV kit, do
not exceed +5.5VDC on the supply.
The MAX1236 EV kit provides a proven PC board lay-
out and software to evaluate the features of the
MAX1236. The Windows software only supports a
2-wire serial interface in S-Mode. To evaluate the
MAX1236 with a user-supplied 2-wire serial interface in
F-Mode or HS-Mode, do the following:
