OPA2990TIDDFR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a layout with a solid ground plane, short traces, and minimal impedance mismatch to minimize noise and distortion. A 4-layer PCB with a dedicated analog ground plane is recommended.
  • To ensure stability, use a compensation capacitor (Cc) between the output and the inverting input pins. The value of Cc depends on the gain and bandwidth requirements. TI provides a stability calculator tool to help determine the optimal value of Cc.
  • The maximum power dissipation of OPA2990 is 1.4W. To calculate the power dissipation, use the formula: Pd = (Vcc x Icc) + (Vout x Iout), where Vcc is the supply voltage, Icc is the quiescent current, Vout is the output voltage, and Iout is the output current.
  • Yes, OPA2990 can be used in a single-supply configuration. However, the input common-mode voltage range is limited to Vcc-1.5V to Vcc+0.5V. To ensure proper operation, use a voltage divider or a voltage reference to set the input common-mode voltage within the recommended range.
  • Use input protection diodes (e.g., 1N4148) or a voltage clamp circuit to limit the input voltage to within the recommended range. Additionally, use a series resistor to limit the input current and prevent damage to the device.
