Replacement verdict
Compatible functional replacement candidate
The ADG407BPZ and ADG406BP are both CMOS analog multiplexers from the same ADG406/ADG407 family, sharing a 28-lead PLCC footprint, dual-supply operation, and comparable on-resistance and switching characteristics. The ADG407BPZ offers 8 differential channels versus the 16 single-ended channels of the ADG406BP, so the two are functionally interchangeable only where the channel configuration and signal routing requirements align. Designers should confirm channel topology and control-logic compatibility before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | ADG407BPZ | ADG406BP | Why it matters |
|---|---|---|---|
| Number of Channels | 8 (differential, 4 pairs) | 16 (single-ended) | Determines whether the device switches differential signal pairs or single-ended lines, which fundamentally changes the signal routing topology. |
| Switch Configuration | 8-to-1 differential multiplexer | 16-to-1 multiplexer | Defines the multiplexer architecture and how many inputs can be routed to a common output, affecting channel count and signal type. |
| On-Resistance (RON) | 50 Ω typical | 50 Ω typical | Lower on-resistance reduces signal attenuation and voltage drop across the switch, important for precision analog signal routing. |
| Supply Voltage Range | ±15 V dual supply (or +12 V single) | ±15 V dual supply (or +12 V single) | Must match the system power rails to ensure proper switching and signal headroom. |
| Package | 28-lead PDIP | 28-lead PDIP | Package footprint and pinout must be compatible for board-level substitution. |
| Channel-to-Channel Matching | 5 Ω typical | 5 Ω typical | Matching between channels affects differential signal integrity and gain consistency across multiplexed paths. |
| Switching Time (tON/tOFF) | 250 ns / 150 ns typical | 250 ns / 150 ns typical | Determines how fast the multiplexer can switch between channels, impacting throughput in multiplexed acquisition systems. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Confirms suitability for industrial and extended-temperature environments. |

Frequently asked questions
What are the key differences between the ADG407BPZ and the ADG406BP?
The ADG407BPZ is an 8-channel differential multiplexer, while the ADG406BP is a 16-channel single-ended multiplexer. Both are CMOS analog multiplexers from Analog Devices in a 28-lead PDIP package, but they differ in channel configuration and switching architecture.
Are the ADG407BPZ and ADG406BP pin-compatible?
No. Although both devices are offered in a 28-lead PDIP (0.6 inch width) package, their pin functions differ because the ADG407BPZ is configured as an 8-channel differential multiplexer and the ADG406BP as a 16-channel single-ended multiplexer. The pinouts are not interchangeable, so PCB layouts must be designed for the specific device.
What are the on-resistance specifications for these devices?
Both the ADG406BP and ADG407BPZ are specified with an on-resistance of typically 50 ohms (maximum 100 ohms) at ±15 V dual supplies, per Analog Devices datasheet parameters for the ADG406/ADG407 family.
What supply voltages do the ADG407BPZ and ADG406BP support?
Both devices operate from dual supplies of ±15 V (range ±10 V to ±18 V) or from a single supply of +12 V to +44 V, consistent with the Analog Devices ADG406/ADG407 datasheet specifications.
What are the switching times of the ADG406BP and ADG407BPZ?
Per the Analog Devices datasheet, both devices feature typical transition times (tTRANSITION) of approximately 160 ns and typical turn-on/turn-off times (tON/tOFF) of about 110 ns/90 ns at ±15 V supplies.
Can the ADG407BPZ be used to multiplex differential signals while the ADG406BP handles single-ended signals?
Yes. The ADG407BPZ is designed as an 8-channel differential multiplexer for differential signal routing, while the ADG406BP is a 16-channel single-ended multiplexer. Selection depends on whether the application requires differential or single-ended signal switching.
Do both devices offer break-before-make switching?
Yes. Both the ADG406BP and ADG407BPZ are specified with break-before-make switching action, which prevents momentary shorting between adjacent channels during channel transitions, as documented in the Analog Devices ADG406/ADG407 datasheet.
What are the typical applications for the ADG406BP versus the ADG407BPZ?
The ADG406BP (16-channel single-ended) is typically used for single-ended signal routing such as data acquisition front ends and test equipment. The ADG407BPZ (8-channel differential) is suited for differential signal multiplexing in instrumentation, audio routing, and precision measurement systems where common-mode rejection is important.
