ADG1422BRMZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG1422BRMZ is a dual single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. It utilizes iCMOS technology to support supply voltages up to ±15 V, +12 V, or ±5 V without requiring a separate logic supply. The device features a maximum on resistance of 2.4 Ω at 25°C and operates with 3 V logic-compatible inputs. It is housed in a 10-lead MSOP package and supports an industrial temperature range from -40°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Inverted digital control logic requires Logic 0 to activate the switches.
• Rail-to-rail operation allows signal ranges extending to the power supplies.
• Flat on resistance profile ensures low distortion for audio and video signals.

Analog Switches, Multiplexers, Demultiplexers Applications

• Automatic test equipment
• Data acquisition systems
• Relay replacements
• Audio signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Ensure that the required logic levels match the inverted control inputs specified for this model variant before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG1422BRMZ when inverted logic control is required compared to the ADG1421. Consider the 10-lead MSOP package dimensions for board space constraints. Verify that the maximum on resistance and leakage current specifications meet the requirements of the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG142x family of high-performance analog switches. It shares the same physical package and core electrical characteristics as the ADG1421 and ADG1423, differing primarily in the polarity of the digital control inputs and switching action behavior.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG1421BRMZ is a direct functional substitute if non-inverted logic control is acceptable. The ADG1423BRMZ offers break-before-make switching suitable for multiplexer applications but has mixed logic polarities between its two channels.

Analog Switches, Multiplexers, Demultiplexers FAQ

Does the ADG1422BRMZ require a separate logic supply voltage?

No, the device does not require a VL supply; it operates directly from the main analog power rails.

What is the maximum continuous current per channel?

The maximum continuous current is 185 mA for the 10-lead MSOP package under standard operating conditions.

How does the ADG1422 differ from the ADG1421?

The ADG1422 has inverted digital control logic, meaning Logic 0 turns the switch on, whereas the ADG1421 uses Logic 1.
