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 supplie
s.
The CA5260, CA5260A have guaranteed specifications for 5V
operation over the full military temperature range of -55
o
C to
125
