Applications

The MAX394EPP is designed to provide single-supply analog switch and voltage-level translation logic. It is suitable for a wide range of different analogue switching applications, such as switching multiple loads, and providing power supply, audio, video, and data control. It can also be used for a number of other applications, such as audio/video level shifting, logic-level conversion, noise suppression, and reset logic. It is also an excellent choice for a wide range of different low-frequency to high-frequency switching applications, such as receivers, transmitters, and amplifier circuits.

Working Principle

The MAX394EPP uses a unique charge pump to provide low-noise and leakage-proof switching with fast and accurate response times. It uses a dual-source internal switch comprising of two n-channel transistors in parallel configuration. The charge pump works by supplying and receiving voltage from a supply voltage source via a string of capacitors and transistors. The capacitors allow for the supply voltage to charge up quickly, while the transistors allow the voltage to be applied quickly to the output. This provides high switching speed and accuracy without the need for an external external charge pump.

The chip also uses two complementary output transistors to provide the voltage-level translation. The two transistors are connected in series and an external voltage source is connected between them. This lets the transistors switch between the voltage source and the output. When the transistors reach the same voltage level, the output voltage is equal to the supply voltage and the switch is off. When the inputs are different, the transistors switch, allowing for the voltage to be translated between the two inputs. This allows for the chip to provide switching and level shifting with a single chip.

Conclusion

The MAX394EPP is an innovative and reliable single-supply analog switch and voltage-level translator. Its features such as an on-chip charge pump, excellent linearity and low leakage current, and high channel to channel isolation, make it an ideal choice for a variety of different applications. It is well-suited for a wide range of low-to-high frequency switching applications, such as receivers, transmitters, and amplifier circuits. As well, it is capable of providing fast and accurate voltage-level translation, making it an excellent choice for audio/video level shifting, logic-level conversion, noise suppression, and reset logic.
