General Description

The MAX5865 evaluation kit (EV kit) is a fully assembled

and tested circuit board that contains all the components

necessary to evaluate the performance of the MAX5865

40Msps analog front end. The MAX5865 integrates a

dual-channel analog-to-digital converter (ADC), a dual-

channel digital-to-analog converter (DAC), and a 1.024V

internal voltage reference. The EV kit board accepts

AC- or DC-coupled, differential or single-ended analog

inputs for the receive ADC and includes circuitry that

converts the transmit DAC differential output signals to

single-ended analog outputs. The EV kit includes cir-

cuitry that generates a clock signal from an AC sine

wave input signal. The EV kit operates from a +3.0V

analog power supply, +3.0V digital power supply, and

±5V bipolar power supply.

The EV kit comes with Windows



98/2000/XP-compatible

software that provides an interface to exercise the fea-

tures of the MAX5865. The program is menu driven and

offers a graphical user interface (GUI) with control but-

tons and status displays. The GUI is used to control the

MAX5865 SPI-compatible serial interface.

The MAX5865 EV kit evaluates the 22Msps MAX5864 or

the 7.5Msps MAX5863 analog front end (IC replace-

ment is required).
