15MHz的，采用BiMOS微处理器与MOSFET的输入运算放大器/ CMOS输出 15MHz, BiMOS Microprocessor Operational Amplifiers with MOSFET Input/CMOS Output
CA5130A and CA5130 are integrated circuit operational amplifiers that combine the advantage of both CMOS and bipolar transistors on a monolithic chip. They are designed and guaranteed to operate in microprocessors or logic systems that use +5V supplies.
Gate protected P-Channel MOSFET PMOS transistors are used in the input circuit to provide very high input impedance, very low input current, and exceptional speed performance. The use of PMOS field effect transistors in the input stage results in common mode input voltage capability down to 0.5V below the negative supply terminal, an important attribute in single supply applications.
