Analog switches provide a connection between two nodes in electronic circuitry. The use of analog switches for electrical isolation has increased over the years, and recently experienced a sharp increase as switch technologies and performance improved. Analog switches such as the AD8118ABPZ, are gaining popularity due to their ability to switch large amounts of current, while providing isolation and low on-resistance. This article will discuss the application field and working principle of the AD8118ABPZ.

The AD8118ABPZ is an ideal choice for applications requiring analog switching, isolation, and high impedance inputs. It is an ultra-low power, low voltage (-40V), high voltage (+40V), and high current (2A) switch. It is designed to provide uniform and reliable performance over a wide range of input levels. With its low voltage and high current capabilities, the AD8118ABPZ is ideal for applications where voltage and current requirements are high, but precise control is not required. Examples of these applications include motor control, power supply switching, and electronic devices. As the AD8118ABPZ is an integrated circuit, it provides for improved power efficiency, small size, and simple control.

The working principle of the AD8118ABPZ is simple and straight-forward. It uses two digital inputs (V1 and V2) to choose between two different voltage ranges. When the input voltage is between V1 and V2, the switch is closed, allowing current to flow through it. When the input voltage is greater than V2 or less than V1, the switch opens and blocks the current. This open/close action is controlled by a logic circuit, which can be programmed to switch at different voltages and resistances for a variety of purposes.

The AD8118ABPZ can be used for a variety of applications including isolation, noise reduction, motor and power supply switching, temperature control, and audio switching. In addition, it can be used as an analog multiplexer, allowing two or more analog inputs to be switched between multiple output devices. For applications requiring low-power operation, the AD8118ABPZ can be used with the AD8118ABPZ low-current switch. For high-power applications, such as automotive systems, the AD8118ABPZ is available in a higher power version.

In conclusion, the AD8118ABPZ is an analog switch offering a variety of potential applications including isolation, noise reduction, motor and power supply switching, temperature control, and audio switching. Its compatibility with the AD8118ABPZ low-current switch makes it possible to use it in low-power applications, while its compatibility with the higher power version makes it suitable for high-power applications. It is controlled by a logic circuit, which can be programmed to switch at different voltages and resistances for a variety of purposes, allowing for improved performance in various conditions.
