4.5MHz, BiMOS Operational Amplifier with

MOSFET Input/Bipolar Output

The CA3140A and CA3140 are integrated circuit operational

amplifiers that combine the advantages of high voltage

PMOS transistors with high voltage bipolar transistors on a

single monolithic chip.

The CA3140A and CA3140 BiMOS operational amplifiers

feature gate protected MOSFET (PMOS) transistors in the

input circuit to provide very high input impedance, very low

input current, and high speed performance. The CA3140A

and CA3140 operate at supply voltage from 4V to 36V

(either single or dual supply). These operational amplifiers

are internally phase compensated to achieve stable

operation in unity gain follower operation, and additionally,

have access terminal for a supplementary external capacitor

if additional frequency roll-off is desired. Terminals are also

provided for use in applications requiring input offset voltage

nulling. 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 for single supply applications. The output stage

uses bipolar transistors and includes built-in protection

against damage from load terminal short circuiting to either

supply rail or to ground.

The CA3140A and CA3140 are intended for operation at

supply voltages up to 36V (±18V).
