ADG408BN

The ADG408BN is an 8-channel single or dual-supply analog multiplexer, designed for low-voltage, low-power system designs, with low on-resistance (RON) and excellent off-isolation (ISO) performance. The device has two select pins that can switch between single-ended and differential input/output modes. This makes the device suitable for applications such as video processing, high-speed input selection, and other analogue or RF signalling requirements. The low power consumption makes it ideal for portable and battery powered applications.

The device is fabricated using CMOS technology and offers premium features such as low power dissipation, low on-resistance, wide bandwidth, low distortion, and low crosstalk. The combination of high performance, low power, and small package size makes the ADG408BN an ideal choice for a variety of applications.

Application Field

The ADG408BN is ideal for applications such as video/audio processors and RF front-end modules. It can also be used in photovoltaic systems, battery-powered systems, mixed-signal systems, and sensors. The ADG408BN is also suitable for automotive and industrial applications.

Working Principle

The ADG408BN is a analog multiplexer. It is designed to switch signals from a single or dual-supply network. The device has two select pins that are used to control the direction of input/output current. When the two select pins remain in their low states, the device is in "single-ended" mode, where the output follows the state of the input. When the two select pins are held in their high states, the device is in "differential" mode, where the output follows the difference between the two select pins.

The device is designed to operate with a supply voltage between 0.5V to 5.5V and has a maximum on resistance (RON) of 62Ω and an off-isoation of 45dB. The device has a maximum signal-to-noise ratio (SNR) of 80dB. The on-resistance is relatively low, which helps reduce power consumption and maintains signal integrity. The device also uses proprietary capacitors which provide low distortion and crosstalk.

The device is rated for temperatures between -40°C to +85°C. The wide temperature range makes it suitable for a variety of automotive and industrial applications. The device also supports a wide range of input/output capacitive loads, allowing it to be used in a variety of applications such as video processing and RF front-end systems.

The ADG408BN is a versatile analog multiplexer. It is capable of switching signals between single-ended and differential modes with low on-resistance and high isolation performance. The device offers high performance and low power consumption, making it suitable for use in a variety of applications.
