Replacement verdict
Compatible functional replacement candidate
The ADG413BRZ and ADG411BRZ are 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 ADG413BRZ adds true rail-to-rail signal handling with dual NC/NO switch configurations, making it a viable functional substitute for the ADG411BRZ in most switching applications, provided the normally-closed channel behavior and slightly higher on-resistance are acceptable in the target design.

Key electrical and mechanical differences between the two devices
| Parameter | ADG413BRZ | ADG411BRZ | Why it matters |
|---|---|---|---|
| Switch Configuration | 4 x SPST (NC) | 4 x SPST (NC) | Both are quad normally-closed SPST switches, so the switching topology is functionally equivalent for signal routing. |
| On-Resistance (RON) | 35 Ω (typ) | 35 Ω (typ) | On-resistance directly affects signal attenuation and voltage drop; matching values support drop-in substitution. |
| Supply Voltage Range | ±4.5 V to ±20 V dual, or +12 V to +44 V single | ±4.5 V to ±20 V dual, or +12 V to +44 V single | Compatible supply ranges ensure the part can operate in the same system power rails without redesign. |
| Channel-to-Channel Crosstalk | -85 dB (typ at 1 MHz) | -85 dB (typ at 1 MHz) | Crosstalk determines signal isolation between channels; identical values indicate equivalent signal integrity. |
| Switching Time (tON/tOFF) | 110 ns / 70 ns (typ) | 110 ns / 70 ns (typ) | Switching speed affects timing-critical multiplexing and sample-and-hold circuits; matching values preserve timing behavior. |
| Leakage Current (Off) | 0.1 nA (typ) | 0.1 nA (typ) | Low off-leakage is critical for high-impedance signal paths and precision measurement accuracy. |
| Package | 16-Lead SOIC (R-16) | 16-Lead SOIC (R-16) | Identical package and pinout allow direct PCB footprint compatibility without layout changes. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Matching temperature ratings ensure both parts meet the same environmental requirements. |

Frequently asked questions
What are the key differences between the ADG413BRZ and ADG411BRZ analog switches?
Both are quad SPST switches in a 16-lead SOIC package from Analog Devices. The ADG411BRZ has normally open (NO) switch contacts, while the ADG413BRZ has normally closed (NC) contacts. Both feature low on-resistance and are controlled by TTL/CMOS-compatible logic inputs.
Are the ADG413BRZ and ADG411BRZ pin-compatible?
Yes, both devices are offered in the same 16-lead SOIC (R-16) package with identical pinouts. The pin functions are the same, but the switch logic state differs: the ADG411BRZ is normally open and the ADG413BRZ is normally closed.
What is the on-resistance of the ADG411BRZ and ADG413BRZ?
Both devices specify a typical on-resistance of 35 Ω and a maximum on-resistance of 70 Ω over the full operating temperature range, per the Analog Devices datasheet.
What supply voltage range do the ADG411BRZ and ADG413BRZ support?
Both devices operate from dual supplies of ±4.5 V to ±20 V, or from a single supply of 4.5 V to 40 V. They are specified for operation over the extended industrial temperature range of −40 °C to +85 °C.
Can the ADG413BRZ be used as a direct drop-in replacement for the ADG411BRZ?
Not without design review. Although the package and pinout are identical, the ADG411BRZ is normally open and the ADG413BRZ is normally closed. The default power-up state of each switch is inverted, so circuit behavior during power-up, power loss, and logic-low conditions will differ.
What are the switching times of the ADG411BRZ and ADG413BRZ?
Per the Analog Devices datasheet, both devices specify a typical turn-on time of 110 ns and a typical turn-off time of 70 ns, with break-before-make switching action.
Do the ADG411BRZ and ADG413BRZ have the same logic threshold and leakage specifications?
Yes. Both devices use TTL/CMOS-compatible logic inputs with a logic high threshold of 2.4 V minimum and a logic low threshold of 0.8 V maximum. Both specify off-channel leakage current of 0.1 nA typical and 1 nA maximum at 25 °C.
