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

-55°C to +125°C.
