5MHz, Low Supply Voltage, Low Input Current BiMOS Operational Amplifiers
The CA5420A is an integrated circuit operational amplifier that combines PMOS
transistors and bipolar
transistors on a single monolithic chip.
It is designed and guaranteed to operate in microprocessor logic systems that use V+ = 5V, V- = GND, since it can operate down to ±1V supplies.
It will also be suitable for 3.
3V logic systems.
The CA5420A BiMOS operational amplifier features gateprotected PMOS
transistors in the input circuit to provide very high input impedance, very low input currents (less than 1pA).
The internal bootstrapping network features a unique guard...
