Description
• MOSFET Input Stage

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.
- Very High Z ; 1.5TΩ (1.5 x 10 Ω) (Typ)

2pA (Typ) at 5V Operation
• Common-Mode Input Voltage Range Includes
Negative Supply Rail; Input Terminals Can be
Swung 0.5V Below Negative Supply Rail
Gate-protected P-Channel MOSFET (PMOS) transistors are
used in the input circuit to provide very high input impedance,
• CMOS Output Stage Permits Signal Swing to Either
(or Both) Supply Rails
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.
• CA5160 Has Full Military Temperature Range
Guaranteed Specifications for V+ = 5V
• CA5160 is Guaranteed to Operate Down to 4.5V for A
OL
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.
• CA5160 is Guaranteed Up to ±7.5V
Applications
• Ground Referenced Single Supply Amplifiers
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

NOTE: CA5160 devices have an on-chip frequency compensation network. Supplementary phase-compensation or frequency roll-off
(if desired) can be connected externally between terminals 1 and 8.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
