DG411CY+ Description

The DG411CY+ is a high-performance SPST (Single Pole Single Throw) analog switch designed by Analog Devices Inc./Maxim Integrated. This switch is part of the DG411 family and is known for its excellent electrical characteristics and robust performance. It features a low on-state resistance (Ron) of up to 45 ohms, ensuring minimal signal attenuation and power loss. The switch operates within a wide supply voltage range of ±4.5V to ±20V for dual supplies and 10V to 30V for single supplies, making it versatile for various applications.

The DG411CY+ boasts a leakage current (IS(off)) of only 250pA, which is crucial for maintaining signal integrity in low-power and high-impedance circuits. Its channel-to-channel matching (ΔRon) is tightly controlled at a maximum of 3 ohms, ensuring consistent performance across multiple channels. Additionally, the switch features a low charge injection of 5pC, which minimizes transient disturbances during switching operations.

The DG411CY+ is housed in a surface-mount 16SOIC package, making it suitable for compact and high-density PCB designs. It is available in a tube package format, facilitating easy handling and integration into manufacturing processes. The device is compliant with RoHS3 and REACH regulations, ensuring environmental sustainability and regulatory adherence.
