ADG442BR

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG442BR 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 dual supplies of ±13.5 V or single supply of 10.8 V. Maximum on resistance is 70 Ω at +25°C and 85 Ω over the industrial temperature range. Switching times are tON < 110 ns and tOFF < 60 ns. Leakage currents are limited to 3 nA max, with charge injection capped at 6 pC.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four independent SPST switches with logic-high activation
• LC2MOS technology ensures flat on-resistance profile for low distortion
• Trench isolation provides latch-up protection for A grade reliability
• Break-before-make switching prevents channel shorting in multiplexer configurations

Analog Switches, Multiplexers, Demultiplexers Applications

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

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and compliance status. The 'BR' designation indicates a Standard Small Outline Package (SOIC-16). Ensure the procurement documentation explicitly states RoHS compliance if required by the manufacturing process. Confirm that the component meets the A grade specification for trench-isolated latch-up proof performance as defined in the manufacturer's datasheet.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG442BR when logic-high control signals are required to activate the switch channels. Unlike the ADG441/ADG444 variants, this model does not require an external VL pin, as the logic power supply is generated internally. It is suitable for applications requiring a maximum supply rating of 44 V and industrial temperature operation between -40°C and +85°C.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG441/ADG442/ADG444 family of LC2MOS Quad SPST switches manufactured by Analog Devices Inc. These devices are designed as plug-in upgrades for legacy DG201A, DG202A, and DG211A parts, and serve as direct replacements for DG441, DG442, and DG444 components. The family shares common electrical characteristics but differs in logic control polarity and voltage requirements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG442BR serves as a plug-in replacement for the DG442. When substituting older DG series parts, verify that the existing circuit logic levels match the ADG442's requirement for logic high inputs to turn on the switches. Ensure the new design accommodates the SOIC-16 footprint if replacing through-hole DIP packages.
