Design Notes
The OPA699M operates from ±5V to ±12V supplies. Ensure adequate supply decoupling with 0.1uF ceramic capacitors close to the V+ and V- pins to maintain stability at high frequencies. For high-speed applications, use a 10uF tantalum capacitor in parallel for low-frequency decoupling.
For optimal performance, place the OPA699M on a ground plane and keep all traces short. The output limiting resistors should be placed close to the LIM+ and LIM- pins to minimize parasitic inductance. Use 1% tolerance resistors for accurate limit voltages.
Do not exceed the absolute maximum supply voltage of ±12V. The output limiting feature requires external resistors; without them, the output may not be clamped, potentially damaging downstream components. Ensure the gain is set to +4 or higher to maintain stability.
