Description

The CA3440 is an integrated circuit operational ampliﬁer that

combines the advantages of MOS and bipolar transistors on

a single monolithic chip.

The CA3440 BiMOS op amp features gate protected PMOS

transistors in the input circuit to provide very high input

impedance, very low input currents (less than 10pA). This

device operates at total supply voltages from 5V to 15V and

can be operated over the temperature range from -55

125

standby power consumption (300nW). This operational

ampliﬁer is internally phase compensated to achieve stable

operation in the unity gain follower conﬁguration. Terminals

are also provided for use in applications requiring input

offset voltage nulling. The use of PMOS in the input stage

results in common mode input voltage capability down to

0.5V below the negative supply terminals, an important

attribute for single supply applications. The output stage

uses MOS complementary source follower form which

permits moderate load driving capability (10k ) at very low

standby currents (50nA).

The CA3440 has the same 8 lead pinout as the “741” and

other industry standard op amps with two exceptions:

terminals one and ﬁve must be connected to the negative

supply or to a potentiometer if nulling is required. Terminal 8

must be programmed through an external resistor returned

to the negative supply.
