Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general op-amp layout guidelines, such as keeping the input and output traces short and away from each other, and using a solid ground plane to reduce noise and electromagnetic interference (EMI).
The choice of gain resistors depends on the desired gain, bandwidth, and noise requirements of your application. TI provides a gain resistor calculator tool to help with this. Additionally, consider the resistor's tolerance, temperature coefficient, and parasitic capacitance when selecting gain resistors.
The maximum power dissipation of the OPA2373AIDGST is dependent on the ambient temperature and the thermal resistance of the package. According to the datasheet, the maximum power dissipation is 1.4W at 25°C. However, it's essential to calculate the power dissipation based on the specific application and ensure it's within the recommended limits to prevent overheating.
Yes, the OPA2373AIDGST can be used as a unity-gain buffer. However, it's essential to ensure that the input impedance is matched to the source impedance to prevent signal attenuation. Additionally, consider the output impedance and load capacitance to ensure stability and prevent oscillations.
To minimize EMI, use a shielded enclosure, keep the input and output traces short and away from each other, and use a solid ground plane. Additionally, consider using EMI filters, such as ferrite beads or common-mode chokes, to reduce radiated emissions.
