REF191GSZ-REEL Frequently Asked Questions (FAQs)

  • A good PCB layout for REF191GSZ-REEL involves placing the device close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC), using a solid ground plane, and keeping the input and output traces short and separate from the power supply traces.
  • To decouple the REF191GSZ-REEL from power supply noise, use a 10uF ceramic capacitor in parallel with a 100nF ceramic capacitor, placed as close to the device as possible, and connected between the VIN pin and the GND pin.
  • The recommended input voltage range for REF191GSZ-REEL is 4.5V to 18V. The output voltage remains stable at 1.9V ± 1% as long as the input voltage is within this range.
  • The REF191GSZ-REEL has a temperature coefficient of 10ppm/°C, which means the output voltage can vary by ±0.019% for every 1°C change in temperature. The device is specified to operate from -40°C to 125°C.
  • Yes, REF191GSZ-REEL can be used in a system with multiple power domains. To handle power sequencing, ensure that the input voltage to the REF191GSZ-REEL is stable and within the recommended range before enabling the output. Use a power-on reset (POR) circuit or a voltage supervisor to ensure proper power sequencing.
