Additional Details

The CA3054D typically operates with a dual power supply (e.g., ±15V). It is available in a 14-lead dual-in-line package (DIP). The exact specifications can vary slightly depending on the manufacturing batch, but generally, it features a high common-mode rejection ratio (CMRR) and a good power supply rejection ratio (PSRR).
