Replacement verdict
Compatible functional replacement candidate
The ADG711BRUZ and ADG712BRU are functionally comparable CMOS analog switches sharing the same TSSOP-16 footprint, dual-supply range, and low on-resistance characteristics, making them viable substitutes in most switching applications. The primary distinction lies in their switch configuration—the ADG711BRUZ provides four normally closed (NC) switches while the ADG712BRU offers four normally open (NO) switches—so designers must verify that the default power-off state aligns with their circuit requirements before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADG711BRUZ | ADG712BRU | Why it matters |
|---|---|---|---|
| Switch Configuration | 4 x SPST (Normally Closed) | 4 x SPST (Normally Open) | Determines the default conduction state of each switch at power-up; NC vs NO changes the logic and fail-safe behavior of the circuit. |
| Number of Channels | 4 | 4 | Channel count must match the signal routing requirements of the application. |
| On-Resistance (RON) | 2.5 Ω (typ) | 2.5 Ω (typ) | Lower on-resistance reduces signal attenuation and voltage drop across the switch, affecting accuracy in analog signal paths. |
| Supply Voltage Range | 1.8 V to 5.5 V | 1.8 V to 5.5 V | Defines compatibility with the system power rail and logic levels. |
| Package / Mounting | 16-TSSOP (Surface Mount) | 16-TSSOP (Surface Mount) | Package and footprint must match the PCB layout for a drop-in substitution. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures reliable operation across the intended environmental conditions. |
| Channel-to-Channel Matching | 0.4 Ω (typ) | 0.4 Ω (typ) | Matching between channels affects differential signal integrity and gain consistency. |
| Switching Time (tON/tOFF) | 14 ns / 8 ns (typ) | 14 ns / 8 ns (typ) | Fast switching times support high-speed signal routing and multiplexing applications. |

Frequently asked questions
What are the key differences between the ADG711BRUZ and ADG712BRU?
The ADG711BRUZ and ADG712BRU are both quad SPST switches from Analog Devices in a 16-lead TSSOP package, but they differ in switch logic. The ADG711 has normally closed (NC) switches, while the ADG712 has normally open (NO) switches. Both are otherwise part of the same ADG711/ADG712 family with matched specifications.
Are the ADG711BRUZ and ADG712BRU pin-compatible?
Yes. Both devices are offered in the same 16-lead TSSOP (RU) package with identical pinouts. The pin functions are the same; the difference is the default switch state (NC for ADG711, NO for ADG712), so the PCB footprint and pin assignments are interchangeable.
What are the on-resistance and supply voltage specifications for these switches?
Both the ADG711 and ADG712 are specified for dual-supply operation of ±2.5 V to ±5.5 V or single-supply operation of 2.5 V to 5.5 V. On-resistance is typically around 2.5 Ω at ±5 V (varies with supply and temperature per the datasheet). Consult the Analog Devices datasheet for the exact guaranteed RON limits over the full operating range.
Can the ADG711BRUZ and ADG712BRU be used interchangeably in a design?
They are not functionally interchangeable without design review because their default states differ: ADG711 channels are closed (NC) when the control input is logic low, while ADG712 channels are open (NO). Substitution changes the power-up and default signal path behavior, so the control logic and fail-safe requirements must be validated before swapping.
What are the switching times and bandwidth of these devices?
Per the Analog Devices datasheet, the ADG711/ADG712 family features fast switching with tON and tOFF in the range of a few nanoseconds (approximately 4 ns typical at ±5 V) and a -3 dB bandwidth on the order of 200 MHz. Exact limits depend on supply voltage and load; refer to the datasheet tables for guaranteed values.
What control logic levels do the ADG711BRUZ and ADG712BRU accept?
Both devices use CMOS/TTL-compatible logic inputs. The digital control inputs are specified with VINH and VINL thresholds per the datasheet, allowing direct interfacing with 3 V and 5 V logic. The logic input controls the switch state: for ADG711 a logic low closes the switch, and for ADG712 a logic high closes the switch.
What are the typical applications for the ADG711BRUZ and ADG712BRU?
These quad SPST switches are used in signal routing, audio and video switching, sample-and-hold circuits, communication systems, and battery-powered instrumentation where low on-resistance and fast switching are required. The choice between ADG711 (NC) and ADG712 (NO) depends on the desired default state at power-up.
