Page 15: Power Supplies
Chapter 4 Power Supplies The Modular MSOP8 EVM board requires 5 V dc for the analog section. This includes the voltage reference (U2), the reference buffer (U4), and optionally, the ADC installed on the EVM (via JMP1). Supply voltages of 1.8 V to 5 V dc for the digital section are also required. -
Page 16: Adc Power
ADC Power 4.1 ADC Power The device installed on the modular MSOP8 EVM has several options in regards to its power source. Refer to the schematic for the following discussion. JMP1 and JMP3 allow the user to select the power supply used by the ADC. When JMP1 is in the default factory position (Shunt on pins 1- 2), power to the ADC comes from J3.3 or TP5. -
