CA3140, CA3140A
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 CA3140A and CA3140 are intended for operation at supply
voltages up to 36V (
±
18V).
