The MAX187 evaluation system (EV system) consists of a
MAX187 evaluation kit (EV kit) board plus a Maxim
68HC16 microcontroller (µC) module. Both boards come
fully assembled and tested, and software is provided. The
unit connects to an IBM-compatible personal computer.
The EV system can function as a data acquisition system,
collecting samples from the MAX187, storing them in mem-
ory, and displaying the conversion results on the host com-
puter. Conversions may be self-timed or synchronized to
an external timebase. Waveforms can be digitized and dis-
played graphically versus time.
The EV system can also evaluate the MAX187’s shutdown
feature, and has provisions for monitoring the supply cur-
rent in the various modes of operation (internal reference,
external reference, or power-down).
Order the EV system (MAX187EVC16-DIP) for comprehen-
sive evaluation of the MAX187 or MAX189. Order the stand-
alone EV kit (MAX187EV KIT-DIP) for custom use or if the
68HC16 module (68HC16MODULE-DIP) has already been
purchased with another Maxim EV system. The MAX187
EV kit can also be used to perform limited evaluation on a
stand-alone basis (see the MAX187 EV Kit Quick Start sec-
tion). The EV system requires an external DC power source
(such as a 12V DC wall transformer) and an IBM-compati-
ble computer with a serial port and a 5 1/4" disk drive. To
evaluate the MAX189, order the MAX187EVC16-DIP plus a
free sample of the MAX189BCPA.
Call toll free 1-800-998-8800 for free samples or literature.
