ADG452BNZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG452BNZ is a monolithic CMOS analog switch IC containing four independent single-pole/single-throw (SPST) switches. Fabricated on an enhanced LC2MOS process, it operates with a maximum supply voltage of 44 V and supports dual supplies from ±4.5 V to ±20 V or a single supply up to 13.2 V. The device features a maximum on resistance of 5 Ω, ultralow power dissipation of 18 μW, and fast switching times with tON at 180 ns maximum and tOFF at 140 ns maximum. It includes TTL/CMOS-compatible digital control logic where a logic high turns the switches on. The component is housed in a 16-lead Plastic Dual In-Line Package (PDIP) and functions within an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Enhanced LC2MOS process technology providing low power dissipation and high switching speed.
• Flat on resistance profile over the full analog input range ensuring excellent linearity.
• TTL and CMOS compatible digital control logic for direct interfacing.

Analog Switches, Multiplexers, Demultiplexers Applications

• Relay replacement
• Audio and video signal switching
• Automatic test equipment
• Precision data acquisition systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'BNZ' corresponds to the lead-free 16-lead PDIP package variant. Confirm that the B version designation aligns with the required industrial operating temperature range of -40°C to +85°C. Ensure compatibility with the intended logic voltage levels before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG452BNZ when non-inverted logic control is required, as a logic high activates the switches. This distinguishes it from the ADG451, which uses inverted logic. Verify that the 5 Ω maximum on resistance meets the circuit requirements and that the 16-lead PDIP package fits the board layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG452BNZ belongs to the ADG451/ADG452/ADG453 family of quad SPST switches. It shares the same physical package and electrical performance characteristics as the ADG451 but differs in digital control polarity. The ADG453 variant offers mixed logic types and break-before-make switching for multiplexer applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG451BNZ serves as a functional substitute if the design accommodates inverted logic control. Other pin-compatible upgrades include the ADG411, ADG412, ADG413, ADG431, ADG432, and ADG433 series.
