CA3140E - 4.5MHz, BiMOS Operational Amplifier with MOSFET Input/Bipolar Output - Intersil Corporation
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 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).
