LME49720NABD: LME49720NA

Part Number: LME49720NABD

I need to know what size decoupling capacitor you recommend for the vcc+ and vcc- terminals on the LME49720na opamp to stop ultrasonic oscillations from causing sound degradation in the mid to upper audio band.  

  • Hi Roger,

    Welcome to e2e.
    Small capacitors, like 0.01uF - 0.1uF are recommended for decoupling high frequencies. Low inductance surface mount ceramic capacitors connected as close as possible to IC pins are recommended.
