4.5MHz, BiMOS Operational Amplifier with  
MOSFET Input/Bipolar Output  
Features  
• MOSFET Input Stage  
- Very High Input Impedance (Z ) -1.5TΩ (Typ)  
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.  
IN  
- Very Low Input Current (I ) -10pA (Typ) at ±15V  
l
- Wide Common Mode Input Voltage Range (V ) - Can be  
lCR  
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  
• Pb-Free Plus Anneal Available (RoHS Compliant)  
Applications  
• Ground-Referenced Single Supply Amplifiers in  
Automobile 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  
The CA3140A and CA3140 are intended for operation at supply  
voltages up to 36V (±18V).  
• All Standard Operational Amplifier Applications  
• Function Generators  
• Tone Controls  
• Power Supplies  
• Portable Instruments  
• Intrusion Alarm Systems
