CA3130
BiMOS Operational Ampli鏗乪r
with MOSFET Input/CMOS Output
Description
CA3130A and CA3130 are integrated-circuit operational
ampli鏗乪rs that combine the advantage of both CMOS and
bipolar transistors on a monolithic chip.
Gate-protected p-channel MOSFET (PMOS) transistors are
used in the input circuit to provide very-high-input imped-
ance, very-low-input current, and exceptional speed perfor-
mance. The use of PMOS 鏗乪ld-effect transistors in the input
stage results in common-mode input-voltage capability down
to 0.5 volt 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 10 millivolts
of either supply-voltage terminal (at very high values of load
impedance), is employed as the output circuit.
The CA3130 Series circuits operate at supply voltages rang-
ing from 5 to 16 volts, or
鹵2.5
to
鹵8
volts when using split
supplies. They can be phase compensated with a single
external capacitor, and have terminals for adjustment of off-
set voltage for applications requiring offset-null capability.
Terminal provisions can also made to permit strobing of the
output stage.
The CA3130A offers superior input characteristics over
those of the CA3130.
