Renesas | CA3140EZ

The CA3140EZ is a 4.5 MHz, BiMOS operational amplifier with MOSFET input/bipolar output. It is available in 8 pin PDIP package.

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

Features:

• MOSFET Input Stage
  • Very High Input Impedance (ZIN) -1.5TΩ (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 Mod 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
• Photocurrent Instrumentation
• Peak Detectors
• Active Filters
• Comparators
• Power Supplies
• Portable Instruments
• Intrusion Alarm Systems
