Dez Dare Voltage Aref Out Reference Selection 2523A AVR 11 02 3 6 Power System Description 3 6 1 Power Supply 3 6 2 ICE50 Power System ICE50 User Guide General Description The ADC is built using analog multiplexers programmable gain instrumentation amplifi ers and a 10 bit successive approximation A D converter This construction should have the same performance as the actual part but since the ADC is located on the POD as an external construction the analog components will be more susceptible to ambient noise and noise from switching IO lines Note Internal analog reference voltage is set to 2 5 volt when using the emulator This differs from part which uses 2 56 V Due to this fact ADC conversions done by the emulator using the internal analog reference voltage differ from the conver sions done in part All inputs to the ADC have serial current limiting resistors of 330Q This is to protect the inputs of the ADC circuit when the emulator is switched off and the target power is present The outputs of the input multiplexers are clamped to Vec and GND and thus when target Vec is present and the emulator power is turned off there will flow a current of approximately Vinput 0 3V 330Q through each ADC input pin The ICE50 needs external power in order to function A switching power adapter is sup plied with the unit The power adapter will accept input voltages in the range of 10
