CA3140, CA3140A  
Data Sheet  
September 1998  
File Number 957.4  
4.5MHz, BiMOS Operational Amplifier with  
MOSFET Input/Bipolar Output  
Features  
• MOSFET Input Stage  
- Very High Input Impedance (Z ) -1.5T(Typ)  
IN  
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.  
- Very Low Input Current (I ) -10pA (Typ) at ±15V

- Wide Common Mode Input Voltage Range (V ) - Can be

Swung 0.5V Below Negative Supply Voltage Rail  
- Output Swing Complements Input Common Mode  
Range  
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.  
• Directly Replaces Industry Type 741 in Most  
Applications  
Applications  
• Ground-Referenced Single Supply Amplifiers in Automo-  
bile and Portable Instrumentation  
• Sample and Hold Amplifiers  
• Long Duration Timers/Multivibrators  
(µseconds-Minutes-Hours)  
• Photocurrent Instrumentation  
• Peak Detectors  
• Active Filters  
• Comparators  
• Interface in 5V TTL Systems and Other Low  
Supply Voltage Systems  
• All Standard Operational Amplifier Applications  
• Function Generators  
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).
