CA5130A and CA5130 are integrated circuit operational amplifiers that bine 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 mon mode input voltage capability down to 0.5V below the negative supply terminal, an important attribute in single supply applications. A plementary symmetry MOS (CMOS) transistor-pair, capable of swinging the output voltage to within 10mV of either supply voltage terminal (at very high values of load impedance), is employed as the output circuit. The CA5130 Series circuits operate at supply voltages ranging from 4V to 16V, or ±2V to ±8V when using split supplies. They can be phase pensated with a single external capacitor, and have terminals for adjustment of offset voltage for applications requiring offset null capability. Terminal provisions are also made to permit strobing of the output stage. The CA5130A, CA5130 have guaranteed specifications for 5V operation over the full military temperature range of -55oC to 125oC.
