ADG528AKN Features

1. Voltage Supply Range: The ADG528AKN operates on a dual supply voltage range of ±10.8V to 16.5V and a single supply voltage range of 10.8V to 16.5V, providing flexibility in power supply requirements.

2. On-State Resistance: The maximum on-state resistance (Ron) is 450 ohms, ensuring low signal loss and minimal distortion during signal routing.

3. Channel-to-Channel Matching: The channel-to-channel matching (ΔRon) is 22.5 ohms, which is crucial for maintaining signal integrity across multiple channels.

4. Channel Capacitance: The channel capacitance (CS(off), CD(off)) is 5pF and 22pF, respectively, contributing to minimal signal delay and distortion.

5. Switch Time: The maximum switch time (Ton, Toff) is 300ns, allowing for fast signal routing and minimal signal loss.

6. Charge Injection: The charge injection is 4pC, which is essential for maintaining signal integrity in high-speed applications.

7. Leakage Current: The maximum leakage current (IS(off)) is 1nA, ensuring minimal power consumption in the off-state.

8. Moisture Sensitivity Level: The moisture sensitivity level (MSL) is 1 (Unlimited), indicating that the device is not sensitive to moisture and can be stored without special precautions.
