Description
- 0.5MHz, Low Supply Voltage, Low Input Current BiMOS Operational Amplifiers
- The CA3420A and CA3420 are integrated circuit operational amplifiers that combine 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).
- Features
- • 2V Supply at 300µA Supply Current
- • 1pA Input Current (Typ) (Essentially Constant to 85oC)
- • Rail-to-Rail Output Swing (Drive±2mA into 1kΩLoad)
- • Pin Compatible with 741 Operational Amplifiers
- Applications
- • pH Probe Amplifiers
- • Picoammeters
- • Electrometer (High Z) Instruments
- • Portable Equipment
- • Inaccessible Field Equipment
- • Battery-Dependent Equipment (Medical and Military)
