4MHz, BiMOS Operational Amplifier with
MOSFET Input/CMOS Output
The CA3160A and CA3160 are integrated circuit operational
amplifiers that combine the advantage of both CMOS and
bipolar transistors on a monolithic chip. The CA3160 series are
frequency compensated versions of the popular CA3130
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 CA3160 Series circuits operate at supply voltages
ranging from 5V to 16V, or ±2.5V to ±8V when using split
supplies, and have terminals for adjustment of offset voltage
for applications requiring offset null capability. Terminal
provisions are also made to permit strobing of the output
stage.
The CA3160A offers superior input characteristics over
those of the CA3160.
