Description
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 imped-
ance), 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 -55oC to
125oC.
