Description

CA3130A and CA3130 are op amps that combine the

advantage of both CMOS and bipolar transistors.

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 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 CMOS transistor-pair, capable of swinging the output volt-

age to within 10mV of either supply-voltage terminal (at very

high values of load impedance), is employed as the output

circuit.

The CA3130 Series circuits operate at supply voltages

ranging from 5V to 16V, (±2.5V to ±8V). They can be phase

compensated with a single external capacitor, and have ter-

minals for adjustment of offset voltage for applications

requiring offset-null capability. Terminal provisions are also

made to permit strobing of the output stage.

The CA3130A offers superior input characteristics over

those of the CA3130.
