DG201BAK

DG201BAK Description

The DG201BAK is an obsolete analog switch from Vishay Siliconix, featuring a single-pole, single-throw (SPST) configuration with four circuits. This through-hole mounted component is housed in a 16-pin CERDIP package, making it suitable for applications requiring robust mechanical stability and ease of installation. The DG201BAK operates within a wide supply voltage range of ±4.5V to ±22V for dual supply and 4.5V to 25V for single supply, offering flexibility in power requirements.

DG201BAK Features

• Low Leakage Current: The maximum leakage current (IS(off)) is rated at 500 pA, ensuring minimal power consumption and maintaining signal integrity when the switch is off.
• Channel-to-Channel Matching: With a ΔRon of 2 ohms, the DG201BAK provides consistent performance across multiple channels, crucial for applications requiring precise signal routing.
• Low On-State Resistance: The maximum on-state resistance (Ron) is 85 ohms, minimizing power loss and ensuring efficient signal transmission.
• Low Charge Injection: At 1 pC, the DG201BAK minimizes transient disturbances, making it ideal for sensitive analog signal processing.
• Fast Switching Times: The switch time (Ton) is a maximum of 300 ns, while the turn-off time (Toff) is 200 ns, enabling rapid signal switching without significant delay.
• Low Channel Capacitance: Both CS(off) and CD(off) are rated at 5 pF, reducing signal distortion and ensuring high-frequency performance.
• Moisture Sensitivity Level: Rated at MSL 1 (Unlimited), the DG201BAK is suitable for a wide range of environmental conditions without the need for special handling.
• Compliance: The DG201BAK is REACH unaffected, ensuring compliance with environmental and safety regulations.
