DG184AP/883 Application Field and Working Principle

The DG184AP/883 is a four channel resistance-controlled Analog switch which is part of a larger group of integrated circuit components that acts as an interface between an analog and digital device. This type of analog switch falls under the category of Interface, Analog Switches, Multiplexers, and Demultiplexers. This switch was developed by Analog Devices and is used in a variety of electronics applications.

The DG184AP/883 is a multi-channel, low-power analog switch. It features four separate channels with common enable, independent data pins, and individual enable pins. Each channel is isolated from the output side and has a high input impedance. In terms of on-resistance, the DG184AP/883 has an exceptional value of only 10 ohms between source and drain, making it suitable for a variety of applications.

The working principle behind the DG184AP/883 is based on a metal-oxide-semiconductor field-effect transistor (MOSFET). When the enable pins 5, 7, 9, and 11 are all enabled, the feedback resistor lattice connected between the drain and source nodes of the MOSFETs act as a voltage controlled current source. When a voltage is applied to the common input, the four MOSFETs will turn on in unison, allowing current to flow from the +5v supply, across the resistor lattice, and out the output.

The switch is used in a variety of applications, including switching audio signals, selecting and addressing chips in a circuit array, and multiplexing data and address lines. Due to its low power dissipation, the DG184AP/883 can be used in circuits with limited power supply. It can also be used in portable microcontroller applications and analog signal processing circuits due to its low-power operation.

The DG184AP/883 is a versatile and reliable switching device that is suitable for a variety of applications. It has a low power dissipation and high on-resistance, making it ideal for use in low-power portable applications. Its ability to withstand high voltage is also useful for controlling signals in high-voltage circuits. The device also provides low switching noise and crosstalk, which makes it a great choice for audio and other high-reliability applications.
