Part Number: RC4558

Can this device be powered by a 9v battery, including losing voltage over time to 8 volts ?

  • Hi Stan,

    Welcome to e2e.
    The mínimum recommended voltaje spec is VCC+=5V and VCC-=-5V. This is a total of 10V.
    If you want to use this device in single-supply, it would need to be at least 10V. 9V down to 8V is below the device spec, the device performance could not be guaranteed at this supply voltage.

    Best regards,
