Replacement verdict
Compatible functional replacement candidate
The ADG604YRUZ and ADG602BRM are both dual SPST CMOS analog switches offering comparable on-resistance and supply range, making the ADG602BRM a viable functional substitute for the ADG604YRUZ in many signal-switching applications. However, the differing package footprint and the ADG604YRUZ's integrated serial-control interface require careful validation before board-level substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADG604YRUZ | ADG602BRM | Why it matters |
|---|---|---|---|
| Number of Switches | 4 (SPST, quad) | 2 (SPST, dual) | Determines how many independent signal paths can be switched; a direct functional substitutability constraint. |
| Switch Configuration | SPST (normally open) | SPST (normally open) | Defines the switching topology; both are normally open, but channel count differs. |
| On-Resistance (RON) | ~2.5 Ω (typical at 5 V) | ~2.5 Ω (typical at 5 V) | Lower on-resistance reduces signal attenuation and insertion loss in the signal path. |
| Supply Voltage Range | 2.7 V to 5.5 V (single supply) | 2.7 V to 5.5 V (single supply) | Must match the system rail to ensure proper switching and logic compatibility. |
| Package / Mounting | TSSOP-14 (surface mount) | MSOP-8 (surface mount) | Footprint and pin count differ, affecting PCB layout and drop-in compatibility. |
| Channel-to-Channel Matching | ~0.4 Ω (typical) | ~0.4 Ω (typical) | Tight matching preserves differential signal integrity across channels. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Ensures reliable operation across industrial and extended temperature environments. |
| Logic Control Interface | CMOS/TTL compatible | CMOS/TTL compatible | Determines compatibility with host microcontroller logic levels. |

Frequently asked questions
What are the key differences between the ADG604YRUZ and ADG602BRM analog switches?
The ADG604YRUZ is a quad SPST switch in a 14-lead TSSOP package, while the ADG602BRM is a dual SPST switch in an 8-lead MSOP package. The ADG604YRUZ offers four independently controlled switches, whereas the ADG602BRM provides two. Both are CMOS analog switches from Analog Devices, but they differ in channel count, package, and pin configuration.
Are the ADG604YRUZ and ADG602BRM pin-compatible?
No. The ADG604YRUZ uses a 14-lead TSSOP package and the ADG602BRM uses an 8-lead MSOP package. They have different pin counts, pin functions, and PCB land patterns, so they are not drop-in replacements for each other.
What are the on-resistance specifications for these two switches?
The ADG604YRUZ has an on-resistance of approximately 2.5 Ω typical at 5 V single supply. The ADG602BRM has an on-resistance of approximately 2.5 Ω typical at 5 V single supply as well. Both are low on-resistance CMOS switches, but designers should verify the exact RON over the intended supply voltage and temperature range from the respective datasheets.
What supply voltage ranges do the ADG604YRUZ and ADG602BRM support?
Both devices operate from a single supply of 2.7 V to 5.5 V or a dual supply of ±2.7 V. The ADG604YRUZ and ADG602BRM are specified for single-supply operation from 2.7 V to 5.5 V and dual-supply operation up to ±2.7 V, making them suitable for portable and battery-powered applications.
How many switches does each device contain and how are they controlled?
The ADG604YRUZ contains four independent SPST switches, each controlled by its own logic input. The ADG602BRM contains two independent SPST switches, each with its own control input. Both use CMOS logic-compatible control inputs.
What are the typical applications for the ADG604YRUZ versus the ADG602BRM?
The ADG604YRUZ, with four switches, is suited for signal routing, multiplexing, and audio/video switching where multiple channels must be controlled. The ADG602BRM, with two switches, is suited for simpler signal routing, sample-and-hold circuits, and portable instrumentation where board space is limited. Both are used in data acquisition, communication systems, and battery-powered devices.
What are the package and temperature range specifications for these parts?
The ADG604YRUZ is supplied in a 14-lead TSSOP package and is specified over the industrial temperature range of −40°C to +85°C. The ADG602BRM is supplied in an 8-lead MSOP package and is also specified over −40°C to +85°C. Both are RoHS-compliant as indicated by the Z and RM suffixes in their part numbers.
