The MAX19700 evaluation system (EV system) consists
of a MAX19700 evaluation kit (EV kit), a companion
Maxim command module (CMOD232) interface board,
and software. Order the complete EV system
(MAX19700EVCMOD2) for comprehensive evaluation of
the MAX19700 using a personal computer. Order the
EV kit (MAX19700EVKIT) 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 MAX19700 EV kit is a fully assembled and tested
circuit board that contains all the components necessary
to evaluate the performance of the MAX19700 analog
front-end (AFE). The MAX19700 integrates a dual
receive analog-to-digital converter (Rx ADC), a dual
transmit digital-to-analog converter (Tx DAC), a 1.024V
internal voltage reference, and three low-speed serial
DACs. The EV kit board accepts AC- or DC-coupled,
differential or single-ended analog inputs for the Rx
ADC and includes circuitry that converts the Tx DAC
differential output signals to single-ended analog outputs.
The EV kit includes circuitry that generates a
clock signal from an AC sine-wave input signal. The EV
kit operates 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) allows a PC to use its serial 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 MAX19700. The program
is menu driven and offers a graphical user interface
(GUI) with control buttons and a status display.
