Description
The CA3140A and CA3140 are integrated circuit operational ampli-
fiers that combine the advantages of high voltage PMOS transis-
tors 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 sin-
gle supply applications. The output stage uses bipolar transistors
and includes built-in protection against damage from load termi-
nal 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).
