Specifications of MAX1276EVKIT

Interface Type
QSPI, Serial (SPI, Microwire)
The MAX1276 evaluation kit (EV kit) consists of an assem-
bled board that can be used with a logic analyzer for
high-speed evaluation of the MAX1276 family of devices
at conversion rates up to 1.8Msps. The MAX1276 EV kit
can be used together with a Maxim 68HC16MODULE-
DIP microcontroller (µC) module for a complete MAX1276
200ksps evaluation system (EV system). Windows
98/ME/XP software provides a convenient user interface
to exercise the MAX1276 and other 5V family members
(see Table 4). When used with a logic analyzer, the EV kit
can be used to evaluate any of the following parts;
MAX1070/MAX1071/MAX1072/MAX1075–MAX1079/
MAX1224/MAX1225/MAX1274–MAX1279, by replacing
the MAX1276 with the desired device.
Order the EV kit (MAX1276EVKIT) for use with a logic
analyzer or if the 68HC16MODULE-DIP has been pur-
chased with a previous Maxim EV system. Order the
complete MAX1276 EV system (MAX1276EVC16) to
receive both the MAX1276 EV kit and 68HC16 boards
for use with a personal computer.
To evaluate other members of the family, request a free
sample and see the Evaluating Other Devices section
for instructions.
