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 CA3140 Series has the same 8-lead pinout used for the

“741” and other industry standard op amps. The CA3140A and

CA3140 are intended for operation at supply voltages up to 36V

( 18V).
