Data Sheet July 11, 2005 FN957.10 4.5MHz, BiMOS Operational Amplifier with Features MOSFET Input/Bipolar Output
• MOSFET Input Stage The CA3140A and CA3140 are integrated circuit operational - Very High Input Impedance (ZIN) -1.5TΩ (Typ) amplifiers that combine the advantages of high voltage - Very Low Input Current (Il) -10pA (Typ) at ±15V PMOS transistors with high voltage bipolar transistors on a - Wide Common Mode Input Voltage Range (VlCR) - Can be single monolithic chip. Swung 0.5V Below Negative Supply Voltage Rail - Output Swing Complements Input Common Mode The CA3140A and CA3140 BiMOS operational amplifiers Range feature gate protected MOSFET (PMOS) transistors in the input circuit to provide very high input impedance, very low • Directly Replaces Industry Type 741 in Most Applications input current, and high speed performance. The CA3140A • Pb-Free Plus Anneal Available (RoHS Compliant) and CA3140 operate at supply voltage from 4V to 36V (either single or dual supply). These operational amplifiers
Applications
are internally phase compensated to achieve stable • Ground-Referenced Single Supply Amplifiers in operation in unity gain follower operation, and additionally, Automobile and Portable Instrumentation have access terminal for a supplementary external capacitor if additional frequency roll-off is desired. Terminals are also • Sample and Hold Amplifiers provided for use in applications requiring input offset voltage • Long Duration Timers/Multivibrators nulling. The use of PMOS field effect transistors in the input (µseconds-Minutes-Hours) stage results in common mode input voltage capability down • Photocurrent Instrumentation to 0.5V below the negative supply terminal, an important attribute for single supply applications. The output stage • Peak Detectors uses bipolar transistors and includes built-in protection • Active Filters against damage from load terminal short circuiting to either supply rail or to ground. • Comparators • Interface in 5V TTL Systems and Other Low The CA3140A and CA3140 are intended for operation at supply Supply Voltage Systems voltages up to 36V (±18V). • All Standard Operational Amplifier Applications • Function Generators • Tone Controls • Power Supplies • Portable Instruments • Intrusion Alarm Systems
