Additional Details:

The MC4558VDX typically has a slew rate in the range of 1V/µs and a gain-bandwidth product of around 1 MHz. This ensures it can handle a wide variety of signal frequencies. The input bias current is typically in the range of tens of nanoamperes, meaning it draws very little current from the input signal source. The operating temperature range usually spans from -40°C to +85°C, making it suitable for operation in a wide range of environments. The common-mode rejection ratio (CMRR) is typically high, meaning it is good at rejecting common-mode noise signals. It's important to consult the datasheet for complete and accurate specifications for any specific application. It comes in a variety of packages, including PDIP and SOIC.
