3.1 Required Equipment for Basic Evaluation

  1. Dual output (positive and negative) floating power supply with output up to 60V and approximately 3A.
    • Two channels or supplies can be used in series to achieve higher voltage. For more information, see Section 3.3.
    • Output current requirements depends on the device load and signal voltages.
  2. Voltage source or function generator to create input voltage signal.
  3. Multimeter to measure DC output voltages or oscilloscope to measure AC output voltages.
  4. Optional: Additional +12V power supply to power heat sink fan.

Figure 3-1 shows a typical setup using the THS3470 EVM, a dual output power supply, function generator, and oscilloscope.
