CA5260, CA5260A
Data Sheet
August 2003
FN1929.4
3MHz, BiMOS Microprocessor Operational
Amplifiers with MOSFET Input/CMOS
Output
The CA5260A and CA507.260 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
o
C to
125
o
C.
