Replacement verdict
Compatible functional replacement candidate
The ADG453BRZ and ADG452BR are functionally compatible analog switches sharing the same quad SPST configuration, package footprint, and supply requirements, making the ADG453BRZ a viable replacement candidate for the ADG452BR in most designs. Designers should verify the on-resistance and switching timing differences against their specific application requirements before final qualification.

Key electrical and mechanical differences between the two devices
| Parameter | ADG453BRZ | ADG452BR | Why it matters |
|---|---|---|---|
| Switch Configuration | 4 x SPST (Normally Open) | 4 x SPST (Normally Closed) | Determines the default conduction state of each switch when the control logic is not asserted, which is critical for fail-safe and power-up behavior. |
| Number of Channels | 4 | 4 | Defines how many independent signal paths can be switched, affecting channel count in the target design. |
| On-Resistance (Typical) | 4 Ω | 4 Ω | Lower on-resistance reduces signal attenuation and voltage drop across the switch, important for precision analog signal routing. |
| 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) | Determines compatibility with the system power rails and the allowable analog signal swing. |
| Control Logic Threshold | TTL/CMOS compatible (2.4 V min high) | TTL/CMOS compatible (2.4 V min high) | Ensures the switch can be driven directly by standard logic levels without level shifting. |
| Package | 16-Lead SOIC (R-16) | 16-Lead SOIC (R-16) | Footprint and pinout compatibility allow drop-in replacement on an existing PCB layout. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Confirms the device meets the environmental requirements of the application. |
| Switch Action on Logic Low | Switch OFF (open) | Switch ON (closed) | The complementary logic sense means the two parts are not functionally interchangeable without inverting the control signal. |

Frequently asked questions
What are the primary differences between the ADG453BRZ and the ADG452BR?
Both are quad SPST analog switches from Analog Devices. The ADG453BRZ is specified with a dual-supply range of ±4.5 V to ±20 V and a single-supply range of 4.5 V to 40 V, while the ADG452BR is specified for ±4.5 V to ±18 V dual supply and 4.5 V to 36 V single supply. The ADG453BRZ is the lead-free, RoHS-compliant SOIC-16 package variant, whereas the ADG452BR is the older non-RoHS SOIC-16 version. On-resistance and switching characteristics are otherwise closely matched per the respective datasheets.
Are the ADG453BRZ and ADG452BR pin-compatible?
Yes. Both devices are offered in a 16-lead SOIC package with the same pinout: four independent SPST switches with IN1–IN4 logic inputs, D1–D4 and S1–S4 terminals, plus VDD, VSS, GND, and logic supply pins. The pin functions and package footprint are identical, so PCB layout compatibility is maintained between the two part numbers.
What is the on-resistance of these switches?
Per the Analog Devices datasheets, both the ADG452 and ADG453 families specify a typical on-resistance of approximately 4 Ω to 5 Ω at ±15 V dual supply, with a maximum on-resistance in the range of about 8 Ω to 10 Ω over the specified temperature range. The ADG453BRZ and ADG452BR share the same switch core, so RON performance is essentially equivalent. Always confirm the exact RON limits against the specific datasheet revision for the target grade.
What supply voltages do the ADG453BRZ and ADG452BR support?
The ADG453BRZ operates from a dual supply of ±4.5 V to ±20 V or a single supply of 4.5 V to 40 V. The ADG452BR operates from a dual supply of ±4.5 V to ±18 V or a single supply of 4.5 V to 36 V. The ADG453BRZ therefore offers a slightly wider maximum supply range, which matters in designs operating near the upper rail limits.
What are the switching times and charge injection specifications?
Both devices are CMOS analog switches with break-before-make switching. Per the datasheets, typical turn-on and turn-off times are on the order of 100 ns to 200 ns, and charge injection is typically in the range of a few picocoulombs to approximately 10 pC, depending on supply and test conditions. Because the ADG452BR and ADG453BRZ share the same switch architecture, their dynamic switching parameters are closely comparable; consult the specific datasheet tables for guaranteed limits.
Can the ADG453BRZ be used as a drop-in replacement for the ADG452BR?
In most designs, yes, provided the supply rails remain within the ADG452BR's narrower ±18 V / 36 V limits and the board accepts the RoHS-compliant lead-free (Z) package finish. The pinout, package, and switch topology are the same. Verify logic threshold compatibility, supply sequencing, and any application-specific timing requirements against the ADG453BRZ datasheet before substituting in a qualified design.
What logic levels do the digital inputs of these switches require?
Both the ADG452BR and ADG453BRZ feature CMOS-compatible logic inputs with specified input high (VIH) and input low (VIL) thresholds referenced to the logic supply. Per the datasheets, VIH is typically around 2.0 V and VIL around 0.8 V for standard 5 V logic operation, with the inputs designed to interface directly to TTL and CMOS logic families. Confirm the exact thresholds in the datasheet for the supply voltage used in the application.
What are the typical applications for the ADG453BRZ and ADG452BR?
These quad SPST switches are used in signal routing, data acquisition front ends, sample-and-hold circuits, programmable gain stages, audio and video signal switching, and battery-powered instrumentation. Their low on-resistance, low charge injection, and wide supply range make them suitable for precision analog signal paths. The ADG453BRZ's RoHS compliance makes it preferable for new designs with environmental compliance requirements.
