The MAX19705–MAX19708 evaluation systems (EV systems)
consist of a MAX19705–MAX19708 evaluation kits
(EV kits), a companion Maxim command module
(CMOD232 or CMODUSB) interface board, and software.
Order the complete EV system (see the Ordering
Information) for comprehensive evaluation of the
MAX19705–MAX19708 using a personal computer.
Order the EV kit if the command module has already
been purchased with a previous Maxim EV system, or for
custom use in other microcontroller-based (µC) systems.
The MAX19705–MAX19708 EV kits are fully assembled
and tested circuit boards that contain all the components
necessary to evaluate the performance of the
MAX19705–MAX19708 analog front-ends (AFEs). The
MAX19705–MAX19708 integrate a dual-receive analog-to-digital converter (Rx ADC), a dual-transmit digital-to-analog converter (Tx DAC), a 1.024V internal voltage
reference, three low-speed serial DACs, and one low-speed
serial ADC. The EV kit boards accept AC- or DC-coupled,
differential or single-ended analog inputs for
the Rx ADC and include circuitry that converts the Tx
DAC differential output signals to single-ended analog
outputs. The EV kits include circuitry that generates a
clock signal from an AC sine-wave input signal. The EV
kits operate from a +3.0V analog power supply, a
+1.8V digital power supply, a +3.0V clock power supply,
and ±5V bipolar power supplies.
The Maxim command module interface board
(CMOD232 or CMODUSB) allows a PC to use its serial
or USB port to emulate an SPI™ 3-wire interface.
Windows® 98/2000/XP-compatible software, which can
be downloaded from www.maxim-ic.com, provides a
user-friendly interface to exercise the features of the
MAX19705–MAX19708. The program is menu driven
and offers a graphical user interface (GUI) with control
buttons and a status display.
