OPA2191ID Frequently Asked Questions (FAQ)
-
A good PCB layout for OPA2191ID involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing decoupling capacitors close to the device. TI provides a reference design and layout guidelines in the datasheet and application notes.
-
The choice of gain resistors depends on the desired gain, bandwidth, and noise requirements. TI provides a gain resistor calculator tool and application notes that can help with selecting the right resistors. Additionally, the datasheet provides guidelines for selecting gain resistors based on the desired gain and bandwidth.
-
The maximum power dissipation of OPA2191ID is dependent on the ambient temperature and the thermal resistance of the package. According to the datasheet, the maximum power dissipation is 750mW at 25°C ambient temperature. However, this can be derated based on the thermal resistance of the package and the ambient temperature.
-
Yes, OPA2191ID 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. Additionally, the output voltage swing is limited to VCC-1.5V to GND+0.5V. TI provides application notes and reference designs for single-supply configurations.
-
Noise and oscillations can be filtered out using a combination of passive and active filtering techniques. TI provides application notes and reference designs that demonstrate the use of RC filters, ferrite beads, and capacitors to filter out noise and oscillations.
