Description
Create a design and simulate using EE-Sim® tools:
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.maximintegrated.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.
