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.

• Ideal for Single Supply Applications
Gate protected P-Channel MOSFET (PMOS) transistors are
used in the input circuit to provide very high input
• Common Mode Input Voltage Range Includes
Negative Supply Rail; Input Terminals Can be Swung 0.5V
Below Negative Supply Rail
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.
• CMOS Output Stage Permits Signal Swing to Either
(Or Both) Supply Rails
• Pb-Free Plus Anneal Available (RoHS Compliant)
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.
Applications
• Ground Referenced Single Supply Amplifiers
• Fast Sample-Hold Amplifiers
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.
• Long Duration Timers/Monostables
• Ideal Interface with Digital CMOS
• High Input Impedance Wideband Amplifiers
• Voltage Followers (e.g. Follower for Single Supply D/A
Converter)
Ordering Information
• Voltage Regulators (Permits Control of Output Voltage
Down to 0V)

*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.
