CA5160

4MHz, BiMOS Microprocessor Operational

Amplifier with MOSFET Input/CMOS

Output

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.

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

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
