CA5260 Datasheet | Intersil

scription The CA5260A and CA5260 are integrated-circuit operational amplifiers that bine 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 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 10m V 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 -55o C to 125o C.
