Dual 3MHz, BiMOS Microprocessor Operational Amplifiers With MOSFET Input/CMOS Output

The CA5260A and CA5260 are integrated-circuit Operational Amplifiers that combine the advantage of both CMOS and bipolar Transistors on a monolithic chip. The CA5260 series circuits are dual versions of the popular CA5160 series. They are designed and guaranteed to operate in Microprocessor 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.
A complementary-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 CA5260 Series circuits operate at supply voltages ranging from 4.5V to 16V, or 2.25V to 8V when using split supplies.
The CA5260 CA5260A have guaranteed specifications for 5V operation over the full military temperature range of -55C to 125C.
