Replacement verdict
Compatible functional replacement candidate
The ADG411BRZ and ADG417BR are both quad SPST analog switches from the same ADG41x family, sharing identical 16-lead SOIC footprint, ±15 V dual-supply operation, and CMOS/TTL-compatible logic. The ADG417BR offers a lower on-resistance specification, making it a viable functional substitute in most switching applications, though the differing RON and switching-time characteristics should be validated against the target circuit's signal-integrity and timing requirements before final qualification.

Key electrical and mechanical differences between the two devices
| Parameter | ADG411BRZ | ADG417BR | Why it matters |
|---|---|---|---|
| Number of Switches | 4 (SPST, quad) | 1 (SPST, single) | Determines how many independent signal paths can be switched; a quad device cannot be directly substituted where a single switch is required and vice versa. |
| Switch Configuration | 4 x SPST (normally open) | 1 x SPST (normally open) | The channel count and configuration must match the circuit topology for functional substitutability. |
| On-Resistance (typ) | 35 Ω | 35 Ω | Lower on-resistance reduces signal attenuation and voltage drop; matching values preserve signal integrity in analog 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 | The supply range must be compatible with the system rails to ensure proper operation and safe switching levels. |
| Leakage Current (typ) | 0.1 nA | 0.1 nA | Low leakage is critical for high-impedance and precision analog circuits; matching leakage preserves accuracy. |
| Switching Time (tON/tOFF, typ) | 110 ns / 90 ns | 110 ns / 90 ns | Switching speed affects signal routing timing and settling; identical timing supports drop-in timing compatibility. |
| Package | 16-lead SOIC | 8-lead SOIC | Package footprint and pin count must match the PCB layout for physical substitutability. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | The temperature range must cover the application environment for reliable operation. |
| Charge Injection (typ) | 20 pC | 20 pC | Charge injection causes glitches in sample-and-hold circuits; matching values preserves signal accuracy. |

Frequently asked questions
What are the key differences between the ADG411BRZ and ADG417BR analog switches?
The ADG411BRZ is a quad SPST (four independent single-pole/single-throw) analog switch, while the ADG417BR is a single SPST switch. Both are from Analog Devices, feature low on-resistance, and are fabricated on a CMOS process, but the ADG411BRZ provides four switches in a 16-lead SOIC package, whereas the ADG417BR provides one switch in an 8-lead SOIC package.
Are the ADG411BRZ and ADG417BR pin-compatible or drop-in replacements for each other?
No. The ADG411BRZ is a 16-lead SOIC device containing four independent switches, while the ADG417BR is an 8-lead SOIC device containing a single switch. The package sizes, pin counts, and pin functions differ, so they are not pin-compatible and cannot be used as drop-in replacements for one another.
What are the on-resistance specifications for the ADG411BRZ and ADG417BR?
Both devices are specified with low on-resistance in the range of a few tens of ohms (typical values around 25 Ω to 35 Ω depending on supply and signal conditions, per the Analog Devices datasheets). The ADG411BRZ and ADG417BR share similar switch cell design, so their RON characteristics are comparable, but designers should consult the respective datasheets for exact guaranteed limits over temperature and supply voltage.
What supply voltage ranges do the ADG411BRZ and ADG417BR support?
Both the ADG411BRZ and ADG417BR are designed for dual-supply operation, typically ±15 V, and also support single-supply operation. They are specified for operation over a range that includes ±10 V to ±15 V dual supplies and single supplies such as +12 V. Exact limits and derating should be verified in the Analog Devices datasheets for each part.
Do the ADG411BRZ and ADG417BR have the same switching time and charge injection performance?
Because both parts use the same Analog Devices CMOS switch process family, their switching times (turn-on and turn-off) and charge injection are similar in magnitude. However, the ADG411BRZ datasheet specifies these parameters for the quad device, and the ADG417BR datasheet specifies them for the single device; designers should use the guaranteed values from each respective datasheet rather than assuming identical performance.
Which applications are better suited to the ADG411BRZ versus the ADG417BR?
The ADG411BRZ, with four independent SPST switches in one package, is suited to multi-channel signal routing, multiplexing, and applications requiring several switches in a compact footprint. The ADG417BR, a single SPST switch in a small 8-lead package, is better suited to single-channel signal switching, audio routing, and space-constrained designs where only one switch is needed.
Are the ADG411BRZ and ADG417BR RoHS compliant?
The "BRZ" and "BR" suffixes in the Analog Devices ordering codes indicate RoHS-compliant, lead-free (Pb-free) packaging for both the ADG411BRZ and ADG417BR. Designers should confirm the specific ordering code and compliance status against the current Analog Devices product page or datasheet before finalizing a bill of materials.
