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
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).
