Replacement verdict
Compatible functional replacement candidate
The ADG411BRZ and ADG413BR are both quad SPST analog switches from the same ADG41x family, sharing identical 16-lead SOIC packaging, ±15 V dual-supply operation, and CMOS/LVTTL-compatible logic inputs. The ADG413BR is a functional replacement candidate for the ADG411BRZ, but the switch logic sense differs: the ADG411BRZ is normally closed (NC) while the ADG413BR is normally open (NO), so circuit behavior must be validated before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADG411BRZ | ADG413BR | Why it matters |
|---|---|---|---|
| Switch Configuration | 4 x SPST (Normally Closed) | 4 x SPST (Normally Open) | Determines the default conduction state of each switch when the control logic is unpowered or at logic low, which is critical for fail-safe and power-up behavior. |
| Number of Channels | 4 | 4 | Defines how many independent signal paths can be switched; matching channel count is required for direct functional substitution. |
| On-Resistance (RON) | 35 Ω (typ) | 35 Ω (typ) | Affects signal attenuation and voltage drop across the switch; similar RON preserves analog signal integrity in the target circuit. |
| Supply Voltage Range | ±4.5 V to ±20 V dual, or 4.5 V to 40 V single | ±4.5 V to ±20 V dual, or 4.5 V to 40 V single | Must match the system power rails to ensure proper operation and to avoid exceeding device ratings. |
| Logic Input Compatibility | TTL/CMOS compatible | TTL/CMOS compatible | Ensures the control pins can be driven directly by standard digital logic levels without level shifting. |
| Switching Time (tON/tOFF) | 110 ns / 90 ns (typ) | 110 ns / 90 ns (typ) | Determines how fast the switch responds to control signals; matching timing keeps system timing behavior consistent. |
| Package | 16-Lead SOIC (R-16) | 16-Lead SOIC (R-16) | Same package and pinout allow drop-in board replacement without layout changes. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Confirms the device is rated for the same environmental conditions in the application. |
| Off Isolation / Crosstalk | 68 dB off isolation, 85 dB crosstalk (typ at 1 MHz) | 68 dB off isolation, 85 dB crosstalk (typ at 1 MHz) | Indicates signal leakage between channels and off-state paths; matching values preserve signal fidelity in multiplexed systems. |

Frequently asked questions
What are the key differences between the ADG411BRZ and ADG413BR analog switches?
The ADG411BRZ is a quad SPST (single-pole single-throw) analog switch with four normally closed (NC) switches, while the ADG413BR is a quad SPST switch configured with two normally open (NO) and two normally closed (NC) switches. Both are members of the Analog Devices ADG411/412/413 family, fabricated on an improved LC2MOS process, and are specified for dual-supply operation with on-resistance typically around 35 Ω. The primary functional distinction is the switch configuration: ADG411 provides four NC channels, whereas ADG413 provides a mixed NO/NC arrangement.
Are the ADG411BRZ and ADG413BR pin-compatible and can they be substituted directly?
Both devices are offered in the same 16-lead SOIC (R-16) package and share the same pinout for supply, ground, and logic control pins. However, because the switch configurations differ (ADG411 = 4×NC; ADG413 = 2×NO + 2×NC), the signal-path behavior at the analog pins differs, so a direct substitution is only valid if the system logic and signal routing are revalidated against the ADG413BR datasheet. Substitution should not be assumed without confirming the NO/NC states required by the target design.
What supply voltage ranges do the ADG411BRZ and ADG413BR support?
Both devices are specified for dual-supply operation, typically ±15 V, and also support single-supply operation. Per the Analog Devices ADG411/ADG412/ADG413 datasheet, the parts operate with dual supplies of ±15 V (with a specified range around ±13.5 V to ±16.5 V for full specification) and with a single supply of +12 V. The digital control inputs are TTL/CMOS compatible. Designers should consult the specific datasheet revision for the exact guaranteed limits before finalizing a design.
What is the on-resistance of the ADG411BRZ and ADG413BR?
Both the ADG411BRZ and ADG413BR are specified with on-resistance (RON) typically around 35 Ω at ±15 V dual supply, with a maximum specified value in the datasheet (commonly cited as 45 Ω maximum for the B grade). On-resistance flatness and matching are also specified. Because RON varies with supply voltage and signal level, the datasheet curves should be consulted for the exact operating conditions of the target application.
What are the switching times and charge injection characteristics of these devices?
The ADG411/ADG412/ADG413 family features fast switching times, with tON and tOFF typically in the range of approximately 100–175 ns depending on supply and grade, and low charge injection (typically on the order of a few picocoulombs to low tens of picocoulombs). These characteristics make the parts suitable for sample-and-hold, data acquisition, and signal-routing applications. Exact tON, tOFF, and charge-injection values should be taken from the Analog Devices datasheet for the specific grade and supply conditions.
What are the typical applications for the ADG411BRZ and ADG413BR?
Both devices are used in precision signal switching applications such as data acquisition systems, sample-and-hold circuits, programmable gain amplifiers, audio and video signal routing, and communication systems. The ADG411BRZ (four NC switches) is often chosen where all channels must default to the closed state, while the ADG413BR (mixed NO/NC) suits designs requiring a defined default state per channel, such as multiplexer/demultiplexer configurations and automatic test equipment.
What package and operating temperature range do the ADG411BRZ and ADG413BR use?
Both parts are available in a 16-lead SOIC package (the "R" suffix in ADG411BRZ denotes the SOIC package, and the ADG413BR is likewise offered in 16-lead SOIC). The "B" grade is specified over the industrial temperature range of −40 °C to +85 °C. Package and temperature-grade information should be confirmed against the ordering guide in the Analog Devices datasheet for the exact part number ordered.
Do the ADG411BRZ and ADG413BR have ESD protection and what are the digital control input thresholds?
The ADG411/ADG412/ADG413 family includes digital inputs that are TTL and CMOS compatible, allowing direct interfacing with standard logic. The devices are fabricated on an LC2MOS process and include protection diodes on the analog and digital inputs. ESD rating and absolute maximum ratings, including digital input voltage limits, are specified in the Analog Devices datasheet; designers should verify these limits and apply appropriate external protection where the application environment demands it.
