CA3130E CA3130EZ OPERATIONAL AMPLIFIER 16V 0.5A 50kHz DIP-8

CA3130 15MHz, BiMOS OPERATIONAL AMPLIFIER WITH MOSFET INPUT/CMOS OUTPUT DIP-8

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 voltage 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 terminals for adjustment of offset voltage for applications requiring offset-null capability. Terminal provisions are also made to permit strobing of the output stage.
