Renesas | CA3140AMZ

The CA3140AMZ is a 4.5 MHz, BiMOS operational amplifier with MOSFET input/bipolar output. It is available in a 8 pin SOIC package.

This device feature gate protected MOSFET (PMOS) transistors in the input circuit to provide very high input impedance, very low input current, and high speed performance. It operates at supply voltage from 4 V to 36 V and combine the advantages of high voltage PMOS transistors with high voltage bipolar transistors on a single monolithic chip.

Features:

• MOSFET Input Stage
  • Very High Input Impedance (ZIN) -1.5T Ω (Typ)
  • Very Low Input Current (Il) -10pA (Typ) at ±15V
  • Wide Common Mode Input Voltage Range (VlCR) Can be Swung 0.5V Below Negative Supply Voltage Rail
  • Output Swing Complements Input Common Mode Range
• 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
