Key electrical and mechanical differences between the two devices
| Parameter | ADG453BRZ | ADG453BR | Why it matters |
|---|---|---|---|
| Number of Switches | 4 | 4 | Defines the channel count; must match for the circuit to be functionally equivalent. |
| Switch Configuration | SPST (Normally Open) | SPST (Normally Open) | Determines the switching topology; identical configuration ensures drop-in compatibility. |
| On-Resistance (Typical) | 4 Ω | 4 Ω | Affects signal attenuation and voltage drop; matching values preserve signal integrity. |
| Supply Voltage Range | ±4.5 V to ±20 V (dual), 4.5 V to 40 V (single) | ±4.5 V to ±20 V (dual), 4.5 V to 40 V (single) | Must be compatible with the system power rails for proper operation. |
| Package / Mounting | 16-Lead SOIC (Surface Mount) | 16-Lead SOIC (Surface Mount) | Footprint and assembly compatibility are essential for physical substitutability. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C (industrial) / commercial variants differ | The Z suffix denotes lead-free/RoHS industrial grade; temperature range affects reliability in harsh environments. |
| RoHS / Lead-Free Status | RoHS Compliant, Lead-Free | Non-RoHS (contains lead) | RoHS compliance is often a regulatory requirement; the Z suffix indicates the lead-free version. |
| Channel-to-Channel Matching | 0.4 Ω (typical) | 0.4 Ω (typical) | Matching ensures consistent signal behavior across channels in multi-channel designs. |
| Switching Time (tON/tOFF) | 90 ns / 60 ns (typical) | 90 ns / 60 ns (typical) | Determines maximum switching frequency and timing accuracy in the application. |

Frequently asked questions
What is the difference between the ADG453BRZ and the ADG453BR?
The ADG453BRZ is the RoHS-compliant, lead-free (Pb-free) version of the ADG453BR. Both are quad SPST CMOS analog switches from Analog Devices in a 16-lead SOIC package with identical electrical specifications; the "Z" suffix denotes the RoHS-compliant molding compound and lead finish, while the ADG453BR is the older non-RoHS version.
Are the ADG453BRZ and ADG453BR electrically and functionally interchangeable?
Yes. Both devices share the same datasheet specifications: quad SPST switches, on-resistance of approximately 4 Ω typical, dual-supply operation (±5 V to ±15 V) or single-supply operation, and TTL/CMOS-compatible logic inputs. The only documented difference is the RoHS/lead-free construction of the ADG453BRZ.
Can the ADG453BRZ be used as a drop-in replacement for the ADG453BR?
Yes, in most cases. Both parts use the same 16-lead SOIC (R-16) package with identical pinout and PCB land pattern, so the ADG453BRZ can directly replace the ADG453BR. Designs requiring RoHS compliance should use the ADG453BRZ.
What package do the ADG453BRZ and ADG453BR use?
Both devices are supplied in a 16-lead SOIC package (Analog Devices package designation R-16). The package outline, pin configuration, and land pattern are the same for both orderable part numbers.
What are the key specifications of the ADG453BRZ and ADG453BR?
Both are quad single-pole single-throw (SPST) analog switches featuring low on-resistance (approximately 4 Ω typical), low leakage current, fast switching times, and low power consumption. They operate from dual supplies of ±5 V to ±15 V or a single supply, with logic inputs compatible with TTL and CMOS levels.
Is the ADG453BRZ RoHS compliant while the ADG453BR is not?
Yes. The "Z" suffix in ADG453BRZ indicates Analog Devices' RoHS-compliant, lead-free construction. The ADG453BR is the legacy non-RoHS orderable part number and should not be specified for new designs requiring RoHS compliance.
Which part number should be used for new designs, ADG453BRZ or ADG453BR?
For new designs, the ADG453BRZ is recommended because it is the RoHS-compliant version and is functionally identical to the ADG453BR. The ADG453BR is a legacy non-RoHS part number and may have limited availability.
