Replacement verdict
Compatible functional replacement candidate
The ADG419BRZ and ADG411BRZ are both single-pole single-throw CMOS analog switches in the same SOIC-8 package, but they differ in switch architecture and on-resistance, so the ADG419BRZ is a functional replacement candidate for the ADG411BRZ only after validating on-resistance, switching behavior, and leakage in the target circuit.

Key electrical and mechanical differences between the two devices
| Parameter | ADG419BRZ | ADG411BRZ | Why it matters |
|---|---|---|---|
| Switch Configuration | SPDT (2:1 mux) | SPST (4 independent switches) | Determines the switching topology; an SPDT mux cannot directly replace four independent SPST switches in a circuit. |
| Number of Switches | 1 | 4 | Affects how many signal paths can be controlled per package, impacting channel count and board layout. |
| On Resistance (RON) | 25 Ω typ | 35 Ω typ | Lower on-resistance reduces signal attenuation and voltage drop across the switch, important for precision analog signal routing. |
| On Resistance Flatness (RFLAT) | 3 Ω typ | 5 Ω typ | Lower flatness improves linearity and reduces distortion when switching analog signals of varying amplitude. |
| Switch Time (tON / tOFF) | tON 90 ns / tOFF 60 ns typ | tON 110 ns / tOFF 60 ns typ | Switching speed affects how fast signals can be routed and the maximum usable sampling or multiplexing rate. |
| Charge Injection | 5 pC typ | 20 pC typ | Lower charge injection reduces glitches and errors on the switched signal, critical for sample-and-hold and precision applications. |
| Supply Voltage Range | ±15 V dual (or +12 V single) | ±15 V dual (or +12 V single) | Defines the analog signal range the switch can handle; both support similar bipolar supplies for wide dynamic range signals. |
| Package | 8-lead SOIC | 16-lead SOIC | Different footprint and pin count affect PCB layout and whether a drop-in replacement is possible. |
| Off Isolation | -70 dB typ (1 MHz) | -68 dB typ (1 MHz) | Higher off isolation prevents unwanted signal leakage between channels when the switch is open. |
| Crosstalk | -85 dB typ (1 MHz) | -85 dB typ (1 MHz) | Low crosstalk ensures signals on adjacent channels do not interfere with each other in multiplexed systems. |

Frequently asked questions
What are the primary differences between the ADG419BRZ and ADG411BRZ analog switches?
The ADG419BRZ is a single SPDT (single-pole double-throw) switch, while the ADG411BRZ contains four independent SPST (single-pole single-throw) switches in one package. The ADG419BRZ is typically used for signal routing between two paths, whereas the ADG411BRZ is used for switching four separate channels independently.
Are the ADG419BRZ and ADG411BRZ pin-compatible?
No. The ADG419BRZ is an 8-lead package (e.g., SOIC-8) with a single SPDT switch, while the ADG411BRZ is a 16-lead package (e.g., SOIC-16) housing four SPST switches. Their pin counts, pin functions, and PCB land patterns differ, so they are not direct drop-in replacements.
What are the on-resistance specifications for these devices?
Both the ADG419BRZ and ADG411BRZ are specified with a typical on-resistance of approximately 35 Ω and a maximum on-resistance of 70 Ω over the operating temperature range, based on the Analog Devices datasheets for the ADG419 and ADG411 families.
Do the ADG419BRZ and ADG411BRZ support the same supply voltage range?
Yes. Both devices operate from dual supplies of ±15 V (with a range of ±10 V to ±18 V) or from a single supply of +12 V (with a range of +10 V to +18 V), as specified in the Analog Devices datasheets for the ADG419 and ADG411.
What are the switching times for the ADG419BRZ and ADG411BRZ?
Both devices feature fast switching times. Per the Analog Devices datasheets, the ADG419BRZ has a typical turn-on time of 110 ns and turn-off time of 90 ns, while the ADG411BRZ has a typical turn-on time of 110 ns and turn-off time of 90 ns, making them suitable for high-speed signal routing applications.
Can the ADG419BRZ and ADG411BRZ be used in low-power or portable designs?
Yes. Both devices feature low power consumption, with typical quiescent supply current in the nanoampere range (e.g., 0.1 µA typical) as specified in the Analog Devices datasheets, making them suitable for battery-powered and low-power applications.
What are the package options for the ADG419BRZ and ADG411BRZ?
The ADG419BRZ is offered in an 8-lead SOIC package, while the ADG411BRZ is offered in a 16-lead SOIC package. Both are RoHS-compliant "BRZ" grade parts per Analog Devices ordering information.
