CA5160 is an integrated circuit operational amplifier that
combines 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 guaranteed to operate in microprocessor or
logic systems that use +5V supplies.

• 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
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.
• CA5160 Has Full Military Temperature Range Guaranteed
Specifications for V+ = 5V
• CA5160 is Guaranteed to Operate Down to 4.5V for A
OL
• CA5160 is Guaranteed Up to ±7.5V
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.
• Ground Referenced Single Supply Amplifiers
• Fast Sample-Hold Amplifiers
• Long Duration Timers/Monostables
• Ideal Interface With Digital CMOS
• High Input Impedance Wideband Amplifiers
The CA5160 operates 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. It has guaranteed
specifications for 5V operation over the full military

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.
