ADG823BRMZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG823BRMZ is a monolithic CMOS dual single-pole, single-throw (SPST) analog switch from Analog Devices. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and features an 8-lead MSOP package. The device contains two independent switches: Switch 1 is normally open, while Switch 2 is normally closed, providing break-before-make switching action. Key electrical parameters include a maximum on resistance of 0.8 Ω at 125°C, a maximum on resistance flatness of 0.3 Ω, and a continuous current carrying capability of 200 mA. The typical power consumption is less than 0.01 μW.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Features low on resistance and high switching speed due to advanced submicron CMOS process technology.
• Supports rail-to-rail operation with TTL- and CMOS-compatible digital inputs.
• Designed for automotive temperature range applications spanning -40°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Applications

• Power routing
• Battery-powered systems
• Data acquisition systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm packaging type and RoHS compliance status. The standard tube version is designated by the BRMZ suffix, while reel options use REEL or REEL7 designations. Confirm that the component meets the required automotive temperature specifications if intended for such environments.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG823BRMZ when a combination of normally open and normally closed SPST switches is required within a single package. Ensure the application voltage falls within the 1.8 V to 5.5 V range and consider the 200 mA current limit for load requirements. Verify compatibility with existing logic levels for control inputs.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ADG821/ADG822/ADG823 family of low-voltage CMOS switches. While sharing identical pinouts and core switching characteristics, the ADG823 is distinct because it combines one normally open switch with one normally closed switch, unlike the ADG821 (both NO) or ADG822 (both NC).

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG721/ADG722/ADG723 are documented as pin-compatible alternatives. However, these legacy parts exhibit higher on resistance values compared to the ADG823 series. Verify that the increased resistance does not impact signal integrity in the target circuit before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the switching configuration of the ADG823?

The ADG823 contains two independent SPST switches where Switch 1 is normally open and Switch 2 is normally closed, exhibiting break-before-make switching action.

Does the ADG823 support bidirectional signal flow?

Yes, each switch conducts equally well in both directions when turned on, allowing the Source and Drain terminals to function interchangeably as inputs or outputs.

What is the maximum operating temperature for this device?

The ADG823 is rated for an automotive temperature range with a maximum operating temperature of +125°C.
