Additional Details

The CA0258M is typically available in an 8-pin DIP (Dual In-line Package). Key specifications include the open-loop voltage gain, input offset voltage, input bias current, slew rate, and bandwidth. The operating temperature range is also a critical parameter. Because Rochester Electronics is the current supplier, their datasheet should be consulted for the most accurate and up-to-date specifications. This op-amp is a good choice for applications where a reliable, general-purpose amplifier is needed, and where continued availability is a concern. It is often used in legacy equipment where a replacement for the original RCA part is required.
