The MAX125/MAX126 evaluation systems (EV systems)
consist of a MAX125/MAX126 evaluation kit (EV kit) and
a Maxim 68HC16MOD-16WIDE microcontroller (µC)
module. The MAX125/MAX126 are high-speed, 8-chan-
nel, 14-bit data-acquisition systems with four simultane-
ous track/holds. Windows 3.1™/Windows 95™ software
provides a handy user interface to exercise the
MAX125/MAX126’s features.
Order the complete EV system for comprehensive eval-
uation of the MAX125/MAX126 with a personal comput-
er. Order the EV kit if you have already purchased the
µC module (68HC16MOD-16WIDE) with another Maxim
EV system or if you desire custom use in other µC-
based systems.
The MAX125/MAX126 EV kits provide a proven PC
board layout to facilitate evaluation of the MAX125/
MAX126. The EV kits must be interfaced to appropriate
timing signals for proper operation. Apply dual power
supplies (±8V min, ±20V max) to connector P1, pin 5
(P1-5), and P1-9, with ground at P1-1. Connect the
active-low read strobe to P1-38, the write strobe to
P1-37, the chip selects to P1-35, and the convert-start
signal to P1-36 (Table 1 and Figure 1). Refer to the
MAX125/MAX126 data sheet for timing requirements.
The MAX125/MAX126 EV systems operate from a user-
supplied +13V to +20V DC power supply. Windows
3.1/Windows 95 software running on an IBM PC inter-
faces to the EV system board through the computer’s
serial-communications port. The software can be oper-
ated with or without a mouse. Refer to the Quick Start
section for setup and operating instructions.
