Find the following types of components
  • Digital to analog converter (DAC)
  • Power and Mode MOSFET
  • PWM MOSFET
  • Sense Resistor
  • PTC Thermistor
Recall the following design goals:
  • Swappable components with easy to solder packages.
  • Low cost.
  • SPI DAC part with 8- 10 bits.
  • MOSFET capable of carrying half an amp in a surface mount package.
  • Moderately accurate sense resistor.
