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
- Very Low I . . . . . . . . . . . . . 5pA (Typ) at 15V Operation

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.
• CA5260A, CA5260 Have Full Military Temperature Range
Guaranteed Specifications for V+ = 5V
• CA5260A, CA5260 are Guaranteed to Operate Down to
4.5V for A
OL
• Fully Guaranteed to Operate from -55°C to +125°C at
V+ = 5V, V- = GND
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.
• Pb-Free Available (RoHS Compliant)
Applications
The CA5260 Series circuits operate at supply voltages
ranging from 4.5V to 16V, or ±2.25V to ±8V when using split
supplies.
• Ground Referenced Single Supply Amplifiers
• Fast Sample-Hold Amplifiers
The CA5260, CA5260A have guaranteed specifications for
5V operation over the full military temperature range of
-55°C to +125°C.
