Design Notes
The LMV358IDT operates from 2.7V to 5.5V. Use a 0.1 µF ceramic capacitor close to the VCC+ pin and a 10 µF electrolytic capacitor for bulk decoupling. Ensure the supply voltage does not exceed 5.5V to avoid damage.
Place the decoupling capacitor as close as possible to the VCC+ pin. Keep the feedback network components close to the inverting input to minimize parasitic capacitance. Use a ground plane to reduce noise.
Do not exceed the input common-mode voltage range (0V to VCC-1.1V). The output can drive capacitive loads up to 100 pF; for larger loads, add a series resistor to maintain stability. Avoid operating with inputs beyond the supply rails.
