CA5260, CA5260A
November 1996
3MHz, BiMOS Microprocessor Operational
Ampli鏗乪rs with MOSFET Input/CMOS Output
Description
The CA5260A and CA5260 are integrated-circuit operational
ampli鏗乪rs 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 鏗乪ld-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
鹵2.25V
to
鹵8V
when using split supplies.
The CA5260, CA5260A have guaranteed speci鏗乧ations for 5V
operation over the full military temperature range of -55

125
