CA3130, CA3130A
15MHz, BiMOS Operational Amplifier with
MOSFET Input/CMOS Output
CA3130A and CA3130 are op amps that combine the
advantage of both CMOS and bipolar transistors.
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 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 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 CA3130 Series circuits operate at supply voltages
ranging from 5V to 16V, (
±2.5V to ±8V). 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 CA3130A offers superior input characteristics over
those of the CA3130.

*Pb-free PDIPs can be used for through hole wave solder processing only. They are not
intended for use in Reflow solder processing applications.
NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate termination finish,
which are RoHS compliant and compatible with both SnPb and Pb-free soldering
operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
