CA3260, CA3260A В® Data Sheet December 10, 2009 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. FN1266.7 Features MOSFET Input Stage provides
-Very High ZI = 1.5TО© (1.5 x 1012О©) (Typ)
-Very Low II 5pA (Typ) at 15V Operation 2pA (Typ) at 5V Operation Ideal for Single Supply Applications Common Mode Input Voltage Range Includes
Negative Supply Rail; Input Terminals Can be Swung 0.5V
Below Negative Supply Rail CMOS Output Stage Permits Signal Swing to Either
(Or Both) Supply Rails Pb-Free 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 The CA3260 Series circuits operate at supply voltages
ranging from 4V to 16V, or В±2V to В±8V when using split
supplies. The CA3260A offers superior input characteristics …
