Part Details for MC4558ID by STMicroelectronics

The maximum power dissipation of the MC4558ID is dependent on the package type and ambient temperature. For the SO-8 package, the maximum power dissipation is 640mW at 25°C. However, this value can be derated based on the ambient temperature and package type. Refer to the thermal characteristics section of the datasheet for more information.

While the MC4558ID is an op-amp, it can be used as a comparator in certain applications. However, it's not recommended as the device is not optimized for comparator operation. The MC4558ID has a relatively slow slew rate and may not provide the desired performance in high-speed comparator applications. STMicroelectronics offers dedicated comparator devices, such as the LM339 or TLV703, which are better suited for comparator applications.

The input impedance of the MC4558ID is typically around 2MΩ, but this value can vary depending on the specific application and operating conditions. The input impedance is composed of the differential input resistance (Rid) and the common-mode input resistance (Ricm). Refer to the electrical characteristics section of the datasheet for more information.

Yes, the MC4558ID can be used in a single-supply configuration. However, the input common-mode voltage range is limited to VCC-1.5V to VCC+0.5V. This means that the input signal should be biased within this range to ensure proper operation. Additionally, the output voltage swing may be reduced in single-supply operation, so ensure that the output voltage requirements are met.

The MC4558ID has a relatively low noise floor, with a typical input voltage noise density of 12nV/√Hz and a typical input current noise density of 0.4pA/√Hz. However, the noise performance can be affected by the operating conditions, such as the supply voltage, temperature, and input impedance. Refer to the noise characteristics section of the datasheet for more information.
