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 -55oC to
125oC. The virtues are programmability and very low
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 (10kΩ) 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.

The CA3440 is pin compatible with the 741 except that pins
1 and 5 (typical negative nulling pins) must be connected
either directly to pin 4 or to a negative nulling potentiometer.
In addition, pin 8, the ISET terminal, must be returned to
either ground or -V via RSET.
