_____MAX1202 Stand-Alone EV Kit

The MAX1202 EV kit provides a proven PC board lay-

out to facilitate evaluation of the MAX1202. It must be

interfaced to appropriate timing signals for proper

operation. Refer to the MAX1202 data sheet for timing

requirements.

Cut JU4 and apply the +5V analog supply between the

+5V pad and the pad marked GND. Connect the

VLOGIC pad to the microprocessor's power supply. Set

JU1 to the 2-3 position (V

= -5V) to allow input sig-

nals between ±4V (Table 1).

_______________General Description

The MAX1202 evaluation system (EV system) is a com-

plete, 8-channel data-acquisition system consisting of a

MAX1202 evaluation kit (EV kit) and a Maxim 3V

68L11D microcontroller (µC) module.

The MAX1202 is a low-power, +5V, 8-channel, 12-bit

analog-to-digital converter (ADC) that connects directly

to 3V and 5V microprocessors (µPs). Windows 3.1™/

Windows 95™ software provides a handy user interface

to exercise the MAX1202’s features.

Order the EV system for comprehensive evaluation of

the MAX1202 using a personal computer. Order the EV

kit if you have already purchased the 68L11D µC mod-

ule with a previous Maxim EV system, or for custom use

in other µC-based systems.

The MAX1202 EV kit and EV system can also be used

to evaluate the MAX1203. Simply order a free sample of

the MAX1203BCPP along with the MAX1202 EV kit. For

3V-only applications, refer to the MAX147 data sheet.

Evaluates: MAX1202/MAX1203 MAX1202 Evaluation Kit ______________MAX1202 EV System The MAX1202 EV system operates from a usersupplied 9V to 15V DC power supply. The Maxim 68L11D 3V µC board uses a MAX667 linear regulator to generate the 3V logic supply. The MAX1202 board uses a 78L05 linear regulator to generate its own 5V analog supply. No level translators are necessary because the MAX1202 VL pin is connected to the 3V logic supply. Quick Start Table 1.

MAX1202 Evaluation Kit Shutdown Power Cycling The MAX1202 can be shut down between conversions to reduce average supply-current demand. From the “Power” menu, select full power-down (FULLPD) or fast power-down (FASTPD) mode. In fast power-down mode, the bandgap reference remains active. The amount of power saved depends primarily on how long the part is off between conversions. The conversion accuracy depends on the power-up delay, the reference capacitor, and the time in power-down.
