CA3260, CA3260A
4MHz, BiMOS Operational Amplifier with
MOSFET Input/CMOS Output
CA3260A and CA3260 are integrated circuit operational
amplifiers that combine the advantage of both CMOS and
bipolar transistors on a monolithic chip. The CA3260 series
circuits are dual versions of the popular CA3160 series.
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 CA3260 Series circuits operate at supply voltages
ranging from 4V to 16V, or ±2V to ±8V when using split
supplies. The CA3260A offers superior input characteristics
over those of the CA3260.

*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.
