Evaluation Kit/Evaluation System for the MAX19700

Active: In Production.

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.
