The DG405BDJ is a four-channel, Digital Low Current Analog Multiplexer/Demultiplexer that can be used in a variety of applications. It is designed to provide high-performance, low-power switching and multiplexing solutions for optical, audio, and industrial sensor applications. In addition, the device can be used in time-division multiplexing (TDM) systems and instrumentation systems.

The DG405BDJ is a digital low current analog multiplexer/demultiplexer with four channels. It is based on a common-control architecture, and utilizes advanced CMOS switching techniques to ensure low distortion and low power consumption. The device offers excellent on-resistance matching, low distortion, low voltage switching, and low switching noise. The on-resistance (R_ON) of the DG405BDJ is typically 2.3 ohms. In addition, the device offers an excellent 0.3V offset voltage and high common-mode rejection ratio (CMRR) of 90dB at 1MHz.

The DG405BDJ has an operating temperature range of -40°C to +85°C. It can be used with a variety of sensors, including RTDs, Wheatstone bridges, photocell detectors, and thermocouples. The device is also suitable for use in medical instrumentation, automotive, and communications applications. The device has a low power dissipation capability and supports both interrupt mode and cascade mode operation. The maximal power dissipation is 2mW, which is suitable for low power and battery-powered applications.

The DG405BDJ employs a push-pull switches and a high-speed digital input. The device is available in a 10-pin small outline package with an 8-bit parallel bus. The bus is used to select the channel, and the switches are used to route the signal to the selected channel. The device can be controlled with 3-state logic and has a wide logic-low threshold of 0.8V to ensure reliable switching in noisy environments. In addition, the device has a maximum on-resistance of 10 ohms and can handle up to a 1A load current.

The DG405BDJ is a useful device for general-purpose analog signal routing and switching applications. It provides a low-cost and low-power solution for a variety of applications. This device is an excellent choice for industrial, automotive, and medical instrumentation applications. It is also suitable for building audio, video, and microphone systems.
