The DG411LDQ-E3 is a dual monolithic CMOS double-pole, double-throw (DPDT) analog switch designed for use in portable and handheld applications. It is designed to trip from off-state to on-state within a wide range of input voltages with an extremely low switch on-resistance. This feature makes it suitable for use in portable electronic consumer products.

Application Field of DG411LDQ-E3

The DG411LDQ-E3 is a highly versatile analog switch device, making it suitable for a wide range of applications. It is ideal for use in signal multiplexing and demultiplexing, mobile communication systems, audio signal routing, portable navigation systems and automotive audio systems. Additionally, it is also suitable for use in analog signal re-direction, data acquisition switching and portable battery-operated equipment.

Working Principle of DG411LDQ-E3

The DG411LDQ-E3 utilizes CMOS (complementary metal-oxide-semiconductor) technology in its design which makes it a low power, low on-resistance analog switch. There is an internal switch controlled by a signal voltage, which is typically between 0V and the full supply voltage. When the signal voltage is below a certain level, the switch is off (open) and when the signal voltage is above the certain level, the switch is on (closed). The signal voltage is usually supplied through an analog input pin.

The signal used in the DG411LDQ-E3 is applied through the signal pin and controls the internal switch. When the signal voltage is less than the “off-Vgs”, the internal switch turns off. Conversely, when the signal voltage is greater than the “on-Vgs”, the internal switch turns on. When the switch is on, the switch between the two inputs is closed and when the switch is off, the switch between the two inputs is open.

The DG411LDQ-E3 analog switch is suitable for use in low-power, portable or handheld applications. It has an extremely low switch on-resistance, making it ideal for use in portable electronic consumer products. Additionally, its wide range of input voltages makes it useful for multiplexing and demultiplexing applications.
