CA5130, CA5130A
15MHz, BiMOS Microprocessor
Operational Amplifiers with MOSFET
Input/CMOS Output
CA5130A and CA5130 are integrated circuit operational
amplifiers that combine the advantage of both CMOS and
bipolar transistors on a monolithic chip. They are designed
and guaranteed to operate in microprocessors 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 CA5130 Series circuits operate at supply voltages ranging
from 4V to 16V, or
±
2V to
±
8V when using split supplies. They
can be phase compensated with a single external capacitor,
and have terminals for adjustment of offset voltage for
applications requiring offset null capability. Terminal provisions
are also made to permit strobing of the output stage.
The CA5130A, CA5130 have guaranteed specifications for
5V operation over the full military temperature range of
-55

C to 125
