OPA658U Frequently Asked Questions (FAQs)
-
Texas Instruments recommends a layout with a solid ground plane, short traces, and minimal impedance mismatch to ensure high-frequency stability and low noise. A 4-layer PCB with a dedicated analog ground plane is recommended.
-
The output filter should be chosen based on the specific application requirements. A 2nd-order Butterworth filter with a cutoff frequency of 10-20 times the signal bandwidth is a good starting point. The filter components should be chosen to minimize impedance mismatch and ensure stability.
-
The OPA658U can drive capacitive loads up to 100pF, but it's recommended to keep the load capacitance below 50pF to ensure stability and prevent oscillations.
-
To reduce noise and EMI, use a low-noise power supply, decouple the power pins with 10uF and 100nF capacitors, and use a shielded enclosure. Additionally, keep the signal traces away from the power traces and use a common-mode choke to filter the output.
-
The OPA658U has a thermal derating of 13.9mW/°C above 25°C. This means that the maximum power dissipation decreases by 13.9mW for every degree Celsius above 25°C.
