Replacement verdict
Compatible functional replacement candidate
The ADG711BRUZ and ADG711BRU are functionally equivalent CMOS analog switches sharing identical channel count, switch configuration, on-resistance, and supply voltage range; the only distinction is the RoHS-compliant versus non-compliant package finish, making the BRUZ a valid drop-in replacement for the BRU in new designs.

Key electrical and mechanical differences between the two devices
| Parameter | ADG711BRUZ | ADG711BRU | Why it matters |
|---|---|---|---|
| Number of Switches | 4 | 4 | Defines how many independent signal paths the device can route; must match for functional substitutability. |
| Switch Configuration | SPST (Normally Closed) | SPST (Normally Closed) | Determines the default conduction state and topology of each switch, which affects circuit behavior at power-up. |
| On-Resistance (Typical) | 2.5 Ω | 2.5 Ω | Low on-resistance minimizes signal attenuation and voltage drop across the switch in signal paths. |
| Supply Voltage Range | 1.8 V to 5.5 V | 1.8 V to 5.5 V | Must be compatible with the system power rail for the part to operate correctly in the target design. |
| Package / Mounting | 16-TSSOP (Surface Mount) | 16-TSSOP (Surface Mount) | Footprint and mounting style must match for drop-in board replacement. |
| RoHS / Lead-Free Status | RoHS Compliant, Lead-Free | Non-RoHS (contains lead) | RoHS compliance affects regulatory acceptance 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 | Ensures the device meets environmental requirements of the application over its full operating range. |
| Channel-to-Channel Matching | 0.4 Ω (typ) | 0.4 Ω (typ) | Tight matching preserves signal integrity across multiple channels in differential or multi-path designs. |

Frequently asked questions
What is the difference between ADG711BRUZ and ADG711BRU?
The ADG711BRUZ and ADG711BRU are the same Analog Devices quad SPST CMOS switch; the "Z" suffix denotes RoHS-compliant lead-free packaging (per Analog Devices ordering guide), while the non-Z version is the older non-RoHS lead-frame variant. Electrical specifications are otherwise identical per the ADG711 datasheet.
Are ADG711BRUZ and ADG711BRU electrically interchangeable?
Yes. Both are the ADG711 quad SPST switch in a 16-lead TSSOP, with the same pinout, on-resistance (typically 2.5 Ω at 5 V single supply), and supply range (1.8 V to 5.5 V single supply or ±2.5 V dual supply) as specified in the Analog Devices ADG711 datasheet. The only documented difference is the RoHS/lead-free construction indicated by the Z suffix.
Can ADG711BRUZ be used as a drop-in replacement for ADG711BRU?
Yes, from an electrical and footprint standpoint they are drop-in compatible: same 16-lead TSSOP package, same pinout, and same specified parameters. The substitution is appropriate where RoHS compliance is required or preferred; verify solder profile and moisture sensitivity level against the current Analog Devices datasheet before production release.
What package do ADG711BRUZ and ADG711BRU use?
Both devices are supplied in a 16-lead TSSOP (Thin Shrink Small Outline Package), designated "RU" in the Analog Devices part numbering. The package body and lead pitch are identical between the two orderable codes.
What are the key switch specifications of the ADG711?
Per the Analog Devices ADG711 datasheet: quad SPST normally open switches, single-supply operation from 1.8 V to 5.5 V (or dual ±2.5 V), low on-resistance of typically 2.5 Ω at 5 V, fast switching times (tON/tOFF on the order of tens of nanoseconds), and low power consumption. These specifications apply equally to ADG711BRUZ and ADG711BRU.
Does the Z suffix affect reliability or performance?
No. The Z suffix in Analog Devices nomenclature identifies RoHS-compliant, lead-free (Pb-free) construction; it does not denote a different silicon die or changed electrical performance. Reliability data should be taken from the current ADG711 datasheet and Analog Devices qualification reports for the specific orderable part number.
Which part number should be specified for new designs?
For new designs, ADG711BRUZ is generally specified because it is the RoHS-compliant orderable variant and aligns with current lead-free assembly and environmental compliance requirements. Confirm current availability and lifecycle status with Analog Devices or an authorized distributor before finalizing the BOM.
