ADG441BN

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG441BN is a monolithic CMOS device comprising four independently selectable SPST switches. It operates on an enhanced LC2MOS process for low power dissipation and high switching speed. The analog signal range extends from VSS to VDD, supporting single or dual supplies. Key electrical parameters include a maximum on-resistance of 70 Ω, a maximum ΔRON of 9 Ω, and a RON match of 3 Ω max. Switching times are tON < 110 ns and tOFF < 60 ns. Leakage currents are limited to 3 nA max, with charge injection at 6 pC max. The device supports continuous current up to 30 mA.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS process provides low power dissipation while maintaining high switching speed and flat on-resistance profile.
• Trench isolation technology ensures latch-up proof performance even under severe overvoltage conditions.
• Break-before-make switching action prevents channel shorting when configured in multiplexer applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package variant, as the ADG441BN denotes the 16-lead Plastic Dual In-Line Package (PDIP). Confirm RoHS compliance status via the suffix 'Z' if required, noting that ordering guides distinguish between standard and compliant parts. Ensure the logic control inputs align with the active-low configuration inherent to the ADG441 model compared to other variants in the family.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG441BN for applications requiring four independent SPST switches with low on-resistance and fast switching speeds. This model activates switches with a logic low input, distinguishing it from the ADG442 which uses logic high. It serves as a direct plug-in replacement for older DG441/DG442/DG444 devices and offers an upgrade path from DG201A/ADG201A families due to improved specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG441 belongs to the ADG441/ADG442/ADG444 series of LC2MOS Quad SPST switches manufactured by Analog Devices. These devices are designed for general-purpose analog signal routing where low distortion and high linearity are critical. The series utilizes trench-isolated CMOS technology to eliminate parasitic junctions, ensuring robust operation across industrial temperature ranges.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly lists the ADG441 as a plug-in replacement for DG441, DG442, and DG444 devices. It also serves as a plug-in upgrade for DG201A/ADG201A, DG202A/ADG202A, and DG211/ADG211A models. Designers should verify pin compatibility and logic polarity differences when substituting these legacy components.
