3MHz, BiMOS Microprocessor Operational
Amplifiers with MOSFET Input/CMOS
Output
The CA5260A and CA5260 are integrated-circuit operational
amplifiers that combine the advantage of both CMOS and
bipolar transistors on a monolithic chip. The CA5260 series
circuits are dual versions of the popular CA5160 series. They
are designed and guaranteed to operate in microprocessor or
logic systems that use +5V supplies.
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 CA5260 Series circuits operate at supply voltages
ranging from 4.5V to 16V, or ±2.25V to ±8V when using split
supplies.
The CA5260, CA5260A have guaranteed specifications for 5V
operation over the full military temperature range of -55°C to
125°C.

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.
