Replacement verdict
Compatible functional replacement candidate
The ADG413BRZ and ADG411BR are quad SPST analog switches from the same Analog Devices ADG411/ADG412/ADG413 family, sharing identical pinout, package, supply range, and switch architecture. The ADG413BRZ is a functionally compatible replacement candidate for the ADG411BR, with the primary distinction being the switch control logic (dual complementary versus normally open), which must be validated against the target circuit's control scheme before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADG413BRZ | ADG411BR | Why it matters |
|---|---|---|---|
| Switch Configuration | 4 x SPST (NC) | 4 x SPST (NC) | Both are quad normally-closed SPST switches, so the switching topology is functionally equivalent for signal routing. |
| On-Resistance (RON) | 35 Ω typ | 35 Ω typ | On-resistance affects signal attenuation and voltage drop; matching values support direct substitution in analog signal paths. |
| Supply Voltage Range | ±4.5 V to ±20 V dual, or 4.5 V to 40 V single | ±4.5 V to ±20 V dual, or 4.5 V to 40 V single | Compatible supply ranges ensure the part can operate in the same rail configuration without redesign. |
| Channel-to-Channel Matching | 3 Ω max | 3 Ω max | Matching between channels affects differential signal accuracy and gain consistency across multiplexed paths. |
| Switching Time (tON/tOFF) | 110 ns / 70 ns typ | 110 ns / 70 ns typ | Switching speed determines bandwidth and timing behavior in multiplexing and sample-and-hold circuits. |
| Leakage Current (Off) | 0.1 nA typ | 0.1 nA typ | Low off-leakage preserves signal integrity in high-impedance and precision measurement applications. |
| Charge Injection | 5 pC typ | 5 pC typ | Charge injection causes glitches in sample-and-hold circuits; matching values ensure equivalent transient performance. |
| Package | 16-Lead SOIC (R-16) | 16-Lead SOIC (R-16) | Identical package and pinout allow drop-in replacement on the same PCB footprint. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Matching temperature ratings confirm suitability for the same environmental conditions. |

Frequently asked questions
What are the main differences between the ADG413BRZ and the ADG411BR?
The ADG413BRZ is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) switches, while the ADG411BR is a quad SPST switch with four normally open (NO) switches. Both are members of the Analog Devices ADG411/412/413 family, offer low on-resistance, and are controlled by TTL/CMOS-compatible logic inputs, but their switch configurations differ.
Are the ADG413BRZ and ADG411BR pin-compatible?
Both devices are offered in a 16-lead SOIC package (the "R" suffix in the BRZ/BR ordering codes denotes SOIC). However, because the ADG413BRZ contains two NC and two NO switches while the ADG411BR contains four NO switches, the logic control and switch terminal assignments differ. Designers must verify the pinout against the respective datasheets before considering a direct replacement.
What are the key analog switch specifications shared by the ADG411BR and ADG413BRZ?
Both parts are quad SPST switches fabricated on Analog Devices' iCMOS process, featuring low on-resistance (typically around 25 Ω), low leakage currents, fast switching times, and TTL/CMOS-compatible control inputs. They operate from dual supplies (e.g., ±15 V) or a single supply and are specified for the industrial temperature range. Exact limits should be confirmed on the current Analog Devices datasheet.
Can the ADG413BRZ be used to replace the ADG411BR in an existing design?
Not as a drop-in replacement without design review. The ADG413BRZ has two normally closed switches, whereas the ADG411BR has four normally open switches. The default power-up state and logic control mapping differ, so the circuit's power-up behavior and control logic must be revalidated against the ADG413BRZ datasheet before substitution.
What supply voltage ranges do the ADG411BR and ADG413BRZ support?
Both devices are designed for dual-supply operation (typically ±15 V) as well as single-supply operation, with the analog signal range extending to the supply rails. The precise minimum and maximum supply ratings, as well as single-supply limits, should be taken from the official Analog Devices datasheet for each part number.
What package options are available for the ADG411BR and ADG413BRZ?
The "BR" and "BRZ" suffixes indicate 16-lead SOIC packaging for both devices. The "Z" suffix on the ADG413BRZ denotes RoHS-compliant lead-free construction. Designers should confirm the exact package and ordering code against the Analog Devices product page or an authorized distributor listing.
Which applications are these quad SPST switches typically used for?
Both the ADG411BR and ADG413BRZ are commonly used for signal routing, data acquisition front ends, sample-and-hold circuits, audio and video switching, and automatic test equipment where low on-resistance and low leakage are required. The choice between them depends on whether normally open or normally closed switch states are needed in the target circuit.
