CA158, CA158A, CA258, CA358, CA358A, CA2904, LM358, LM2904 are dual, 1MHz, operational amplifiers for commercial industrial, and military applications from the brand DINGHAO. They are designed specifically to operate from a single power supply over a wide range of voltages. They may also be operated from split power supplies.
The CA158/CA158A/CA258/CA258A/CA358/CA358A/CA2904/LM358/LM2904 family consists of dual, internally frequency‑compensated operational amplifiers designed for single‑supply operation over a wide voltage range and also compatible with split supplies. They are suited for interface circuits with digital systems, transducer amplifiers, and general‑purpose op‑amp applications.
The datasheet details absolute maximum ratings, operating temperature ranges, thermal resistance, and electrical specifications such as gain, bandwidth, input bias current, and output swing. Typical performance curves illustrate supply current drain, voltage gain versus supply voltage, and output current versus temperature, while a schematic diagram and mask layout provide physical design information.
