The MDN-B3 ADC demo board demonstrates Linear Tech's LTC1865L ADC in conjunction with Altera's MAXII CPLD. The demo board (supplied with a sample demonstrating programming file) uses the analog signals received from a 2 axes resistive joystick to control a few applications. Supplied demo program uses resources on the demo board such as a LCD module, a dual channel stepper motor controller/ driver and a tri-color LED. Use the demo board to develop your own designs that require a high density CPLD, an ADC and versatile input and output options that are available on the MDN-B3

The demo board is powered using LT's LDO regulators LT1763-3.3 and LT1086-5. Requires external power supply of 12V.
