The MAX194 Evaluation System (MAX194EVC16-DIP)
includes the MAX194 evaluation kit and Maxim’s
68HC16 module. Evaluation software supplied with the
kit demonstrates the use of the MAX194 (or the
MAX195) with Motorola’s high-speed QSPI serial inter-
face. Complete source code is included. The EV sys-
tem requires an IBM PC with a serial port and a 5 1/4"
disk drive.
The stand-alone MAX194 Evaluation Kit (MAX194
EVKIT-DIP) is an assembled and tested PC board that
embodies the standard application circuit. Separate
power, digital, and analog ground planes minimize
noise. Jumpers allow several operating modes. The
board generates its own interface timing signals, or can
be connected to a user-provided serial interface.
