Replacement verdict
Compatible functional replacement candidate
The ADG411BRUZ and ADG411BRU are functionally equivalent CMOS quad SPST analog switches sharing identical on-resistance, channel count, and signal range characteristics; the only distinction is the RoHS-compliant, lead-free construction of the ADG411BRUZ versus the leaded ADG411BRU. The ADG411BRUZ is a suitable functional replacement candidate for the ADG411BRU in new designs, provided the lead-free package and compliance requirements are acceptable.

Key electrical and mechanical differences between the two devices
| Parameter | ADG411BRUZ | ADG411BRU | Why it matters |
|---|---|---|---|
| Number of Switches | 4 | 4 | Determines how many independent signal paths the device can route; must match for functional substitutability. |
| Switch Configuration | SPST (Normally Closed) | SPST (Normally Closed) | Defines the switching topology; identical configuration ensures the same circuit behavior. |
| On-State Resistance (RDS(on)) | 35 Ω (typ) | 35 Ω (typ) | Affects signal attenuation and voltage drop; matching values preserve signal integrity. |
| Supply Voltage Range | ±4.5 V to ±20 V (dual), 12 V to 40 V (single) | ±4.5 V to ±20 V (dual), 12 V to 40 V (single) | Must be compatible with the system power rails for correct operation. |
| Channel-to-Channel Matching | 3 Ω (typ) | 3 Ω (typ) | Low matching error ensures consistent gain across channels in multiplexed signal paths. |
| Switching Time (tON/tOFF) | 110 ns / 90 ns (typ) | 110 ns / 90 ns (typ) | Determines maximum switching frequency and timing accuracy in the application. |
| Package / Mounting | 16-TSSOP (Surface Mount) | 16-TSSOP (Surface Mount) | Footprint and mounting style must match for PCB compatibility. |
| RoHS Compliance | RoHS Compliant (Pb-free) | Non-RoHS (contains lead) | RoHS status affects regulatory compliance and solder process compatibility; the "Z" suffix denotes the lead-free variant. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Must cover the application's environmental conditions for reliable operation. |

Frequently asked questions
What is the difference between ADG411BRUZ and ADG411BRU?
The ADG411BRUZ is the RoHS-compliant, lead-free (Pb-free) version of the ADG411BRU. Both are quad SPST analog switches in a 16-lead TSSOP package from Analog Devices, but the "Z" suffix denotes compliance with RoHS/lead-free manufacturing requirements, while the ADG411BRU is the non-RoHS legacy ordering code.
Are ADG411BRUZ and ADG411BRU functionally and electrically identical?
Yes. Both devices share the same datasheet specifications: quad SPST switches, on-resistance of approximately 35 Ω typical, dual-supply operation of ±15 V (or single +12 V), low leakage current, and TTL/CMOS-compatible logic inputs. The only documented difference is the RoHS/lead-free status indicated by the "Z" suffix.
Can ADG411BRUZ be used as a direct drop-in replacement for ADG411BRU?
Yes, in most cases. Both parts use the same 16-lead TSSOP package with identical pinout and the same electrical specifications. The ADG411BRUZ is the recommended replacement since it is RoHS-compliant, but PCB land patterns and pin functions are unchanged.
What package do ADG411BRUZ and ADG411BRU use?
Both devices are supplied in a 16-lead TSSOP (Thin Shrink Small Outline Package), designated by the "RU" suffix in the ordering code. The package dimensions and pin assignments are identical between the two variants.
What are the key analog switch specifications of the ADG411 family?
The ADG411 is a quad SPST analog switch featuring low on-resistance (approximately 35 Ω typical), low off leakage (around 0.1 nA typical), fast switching times (tON ≈ 110 ns, tOFF ≈ 90 ns typical), and operation from ±15 V dual supplies or +12 V single supply. These specifications apply equally to ADG411BRUZ and ADG411BRU.
Why is the ADG411BRUZ preferred over the ADG411BRU for new designs?
The ADG411BRUZ carries the "Z" suffix indicating RoHS compliance and lead-free construction, which is required for products sold in regions with RoHS regulations (such as the EU). The ADG411BRU is the older non-RoHS ordering code and may not satisfy current environmental compliance requirements.
Do ADG411BRUZ and ADG411BRU differ in operating temperature range or supply voltage?
No. Both variants are specified over the industrial temperature range of −40 °C to +85 °C and support the same supply voltages: dual ±15 V or single +12 V operation, with logic inputs compatible with TTL and CMOS levels. No electrical or thermal specification differs between the two ordering codes.
