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.

Ordering Information

*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.
