ADG451BN

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG451BN is a monolithic CMOS device comprising four independently selectable single-pole/single-throw switches. Fabricated on an enhanced LC2MOS process, it features a maximum on resistance of 5 Ω and ultralow power dissipation of 18 μW. The analog signal range extends to the supply rails, supporting dual supplies from ±4.5 V to ±20 V or a single supply as low as 5.0 V. Digital control inputs are TTL/CMOS compatible, with switching times of 70 ns (tON) and 60 ns (tOFF).

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS process provides low power dissipation and high switching speed.
• On resistance profile remains flat over the full analog input range for excellent linearity.
• Analog signal range fully extends to the supply rails in both single and dual supply configurations.
• TTL and CMOS compatible digital control logic simplifies interface design.

Analog Switches, Multiplexers, Demultiplexers Applications

• Relay replacement circuits
• Audio and video signal switching
• Automatic test equipment
• Precision data acquisition systems
• Battery-powered portable instruments

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package variant against project requirements, as the ADG451 series includes DIP, SOIC, and TSSOP options. Confirm RoHS compliance status, noting that suffixes such as Z indicate lead-free construction. Ensure the ordering suffix matches the desired manufacturing standard and environmental certification before finalizing procurement documentation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG451BN when low on resistance and flatness are critical for signal integrity. This component is suitable for applications requiring operation from a single 5 V supply up to ±20 V dual supplies. Consider the ADG453 variant if break-before-make switching action is required for multiplexer configurations to prevent channel shorting.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG451BN belongs to the ADG451/ADG452/ADG453 family of quad SPST analog switches. It serves as a pin-compatible upgrade for older ADG411 and ADG431 series devices. The 'B' designation indicates the industrial temperature range of -40°C to +85°C, while the 'N' suffix specifies the 16-lead plastic dual in-line package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG451BRZ and ADG451BRUZ are functional equivalents offering surface-mount packaging alternatives. These variants maintain identical electrical specifications and pinouts, allowing for direct board layout adaptation without circuit redesign. Verify that the selected surface-mount package fits the available footprint constraints.
