VCA821ID Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the VCA821ID is 1.65V to 5.5V, with a typical operating voltage of 3.3V or 5V.
  • To ensure proper biasing, connect the VBIAS pin to a voltage source that is 1.2V to 1.5V above the supply voltage (VCC). This sets the internal bias voltage for the amplifier.
  • The maximum input voltage that can be applied to the VCA821ID is 6V, which is the absolute maximum rating. However, for normal operation, the input voltage should be limited to the supply voltage (VCC) or less.
  • To minimize noise and distortion, use a low-ESR capacitor (e.g., ceramic or film capacitor) for decoupling, keep the input and output traces short and away from noise sources, and use a quiet power supply.
  • Yes, the VCA821ID can be used as a voltage-controlled resistor (VCR) by connecting the output to the inverting input and using the control voltage to vary the resistance.
