Low Power QUAD Operational Amplifiers

Transcription

1 Low Power QUAD Operational Amplifiers Product Description The GS4 consists of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drains in independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op amp circuits, which now can be more easily implemented in single power supply systems. For example, the GS4 can be directly operated off of the standard + power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional± power supplies. Features Wide range of supply voltages to Low supply current drain independent of supply voltage.ma TYP. Low input biasing current Low input offset voltage and offset current Input common-mode voltage range includes ground Differential input voltage range equal to the power supply voltage DC voltage gain: /m TYP.
