Description
CA5160 is an integrated circuit operational amplifier that com-
bines the advantage of both CMOS and bipolar transistors on
a monolithic chip. The CA5160 is a frequency compensated
version of the popular CA5130 series. It is designed and guar-
anteed 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 CA5160 operates at supply voltages ranging from +5V to
+16V, or
±
2.5V to
±
8V when using split supplies, and have ter-
minals for adjustment of offset voltage for applications requir-
ing offset-null capability. Terminal provisions are also made to
permit strobing of the output stage. It has guaranteed specifi-
cations for 5V operation over the full military temperature
range of -55
