The MAX1292 evaluation kit (EV kit) is assembled with a

MAX1292 and the basic components necessary to eval-

uate this 12-bit analog-to-digital converter (ADC).

Connectors for power supplies, analog inputs, and digital

signals simplify connections to the device. A 40-pin

header allows the user to connect a logic analyzer using

a ribbon cable or conventional minihooks. BNC connec-

tors with 50Ω terminations provide easy connection

between function generators and the analog inputs.

The board layout is designed to yield 12-bit accuracy

with low noise when sampling at the maximum rate of

400ksps.

The MAX1292 EV kit can also be used to evaluate the

MAX1293. Request a free sample of the MAX1293BCEG

when ordering the MAX1292 EV kit.

General Description

Component List

DESCRIPTION

MAX1292 Evaluation Kit

o 12-Bit Analog-to-Digital Conversion

o Four Input Channels

o Byte-Wide Digital Interface

o Internal Track/Hold

o 400kHz Sampling Rate

o Internal 2.5V Reference

o Internal Clock

o Low-Power Standby Mode

o Fully Assembled and Tested Surface-Mount Board

The MAX1292 EV kit comes fully tested and assembled.

The following equipment is required:

• A +5V linear power supply. Switching supplies

• A low-distortion function generator

• A logic analyzer

A logic analyzer or other digital system is needed to

provide the clock and control signals and to capture

the MAX1292 conversion results. Connect the logic

analyzer using a 40-pin ribbon cable, or a combination

of BNC cables, ribbon cable, and miniclips. Refer to the

MAX1292 data sheet for detailed information on timing

requirements.

The analog input signals must be delivered by a low-

distortion source to achieve full 12-bit accuracy. All

analog channels connect to BNC connectors terminated

with 51Ω resistors. For low-noise performance, maintain

separate analog and digital supplies and grounds to

the board. The grounds are connected in a star config-

uration centered on the ground plane of the board.

Refer to the MAX1292 data sheet for a detailed discus-

sion of signal grounds.

Many of the digital and analog signals on the evaluation

kit have 51Ω termination resistors matching typical gen-

erator impedance. These should be removed if high-

impedance sources are used.
