DG201BDJ-E3 Description

The DG201BDJ-E3 is a high-performance SPST-NC (Single Pole, Single Throw, Normally Closed) analog switch designed by Vishay Siliconix. This through-hole mounted IC is housed in a 16-DIP package and is ideal for a wide range of applications requiring reliable switching performance. The DG201BDJ-E3 features a maximum on-state resistance (Ron) of 85 ohms, ensuring minimal power loss and high efficiency signal in transmission. It operates over a wide supply voltage range of ±4.5V to ±22V for dual supply and 4.5V to 25V for single supply, making it versatile for various power requirements.

The DG201BDJ-E3 boasts excellent channel-to-channel matching with a ΔRon of 2 ohms, ensuring consistent performance across multiple channels. Its leakage current (IS(off)) is limited to a maximum of 500pA, which is crucial for maintaining signal integrity and reducing power consumption in low-power applications. Additionally, the switch offers a fast switching time with a maximum turn-on time (Ton) of 300ns and turn-off time (Toff) of 200ns, enabling rapid signal switching without significant delays.

The DG201BDJ-E3 also features low charge injection (1pC) and low channel capacitance (CS(off), CD(off)) of 5pF, which are critical for maintaining signal fidelity and minimizing signal distortion. These attributes make the DG201BDJ-E3 suitable for high-speed and high-precision applications where signal integrity is paramount.
