CA3420 Datasheet 0.5mhz/ Low Supply Voltage/ Low Input Current Bimos Operational Amplifiers

Manufacturer: Intersil (now Renesas)

Overview: CA3420, CA3420A TM Data Sheet April 2000 File Number 1320.6 0.5MHz, Low Supply Voltage, Low Input Current BiMOS Operational Amplifiers The CA3420A and CA3420 are integrated circuit operational amplifiers that bine PMOS transistors and bipolar transistors on a single monolithic chip. The CA3420A and CA3420 BiMOS operational amplifiers feature gate protected PMOS transistors in the input circuit to provide very high input impedance, very low input currents (less than 1pA).

Key Features

  • a unique guardbanding technique for reducing the doubling of leakage current for every 10oC increase in temperature. The CA3420 series operates at total supply voltages from 2V to 20V either single or dual supply. These operational amplifiers are internally phase compensated to achieve stable operation in the unity gain follower configuration. Additionally, they have access terminals for a supplementary external capacitor if additional frequency roll-off is desired. Terminals are also provided for.
