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
-55°C to +125°C.
