Description

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. Because of

this unique combination of technologies, this device can now provide

designers, for the ﬁrst time, with the special performance features of

the CA3130 CMOS operational ampliﬁers and the versatility of the 741

series of industry standard operational ampliﬁers.

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 per-

formance. 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).
