The maximum power dissipation of the MC4558IN is dependent on the package type and ambient temperature. For the DIP package, it is 500mW at 25°C, while for the SO8 package, it is 320mW at 25°C. Refer to the thermal characteristics section of the datasheet for more information.
To ensure stability in a unity-gain configuration, it is recommended to add a capacitor (typically 10-100pF) between the output and the inverting input pins. This helps to compensate for the internal pole and ensures stability.
The recommended supply voltage range for the MC4558IN is ±2V to ±18V. However, it is recommended to operate the device within the specified operating conditions to ensure optimal performance and reliability.
While the MC4558IN can be used as a comparator, it is not recommended due to its relatively slow slew rate (0.5V/μs) and limited output current (±20mA). A dedicated comparator IC would be a better choice for most applications.
To prevent electrostatic discharge (ESD) damage, it is recommended to handle the MC4558IN with an anti-static wrist strap or mat, and to ensure that the device is stored in an anti-static package or bag.
