Replacement verdict
Compatible functional replacement candidate
The ADG406BP and ADG407BP are functionally comparable CMOS analog multiplexers from the same ADG406/ADG407 family, sharing identical supply requirements, package footprint, and control interface. The primary distinction is the switch configuration: the ADG406BP provides an 8-channel single-ended multiplexer configuration, while the ADG407BP provides a 4-channel differential multiplexer configuration. Because the channel topology differs, the ADG407BP is not a direct drop-in substitute for the ADG406BP in circuits that require single-ended 8-to-1 multiplexing; however, both parts are viable functional replacement candidates where the system architecture can accommodate the respective channel configuration. Designers should confirm the required channel topology and verify pin-level signal routing before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADG406BP | ADG407BP | Why it matters |
|---|---|---|---|
| Switch Configuration | 8-channel single-ended (1-of-8 multiplexer) | 4-channel differential (2-of-8 differential multiplexer) | Determines whether the device routes single-ended or differential signals, which fundamentally affects the circuit topology and cannot be substituted without redesign. |
| Number of Channels | 8 single-ended channels | 4 differential channels (8 inputs) | Channel count dictates how many signal sources can be multiplexed; the two parts serve different channel-count requirements. |
| On-Resistance (RON) | 50 Ω typical | 50 Ω typical | On-resistance affects signal attenuation and accuracy; matching values mean similar insertion loss behavior. |
| Supply Voltage Range | ±15 V dual supply (or +12 V single) | ±15 V dual supply (or +12 V single) | Supply range must match the system rails; identical ranges allow use in the same power environment. |
| Package | 28-lead PDIP | 28-lead PDIP | Package compatibility determines whether the part can drop into the same PCB footprint. |
| Switching Time (tON/tOFF) | ~250 ns / ~150 ns | ~250 ns / ~150 ns | Switching speed affects multiplexing rate and settling; identical timing means comparable dynamic performance. |
| Off Isolation | ~68 dB at 1 MHz | ~68 dB at 1 MHz | Off isolation determines crosstalk between unselected channels; matching values indicate similar signal integrity. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range must cover the application environment; identical ratings allow use in the same conditions. |

Frequently asked questions
What is the primary difference between the ADG406BP and ADG407BP?
The ADG406BP is an 8-channel analog multiplexer (1-of-8), while the ADG407BP is a dual 4-channel analog multiplexer (2-of-4). Both are CMOS devices in a 28-lead PLCC package, but they differ in channel configuration and switching topology.
Do the ADG406BP and ADG407BP have the same on-resistance specification?
Yes. Both devices specify a typical on-resistance of 50 Ω and a maximum on-resistance of 100 Ω over the operating temperature range, per the Analog Devices datasheet.
Are the ADG406BP and ADG407BP pin-compatible?
No. Although both are housed in a 28-lead PLCC package, the pin functions differ because the ADG406BP is a single 8-channel multiplexer and the ADG407BP is a dual 4-channel multiplexer. The pinouts are not interchangeable and must be verified against the respective datasheets before substitution.
What supply voltage range do the ADG406BP and ADG407BP support?
Both devices operate from dual supplies of ±15 V (typical) and support a range of ±10 V to ±18 V, as well as single-supply operation from +10 V to +30 V, per the Analog Devices datasheet.
What are the switching times for the ADG406BP and ADG407BP?
Both devices specify a typical turn-on time of 250 ns and a typical turn-off time of 150 ns, according to the Analog Devices datasheet.
Can the ADG406BP and ADG407BP be used in single-supply applications?
Yes. Both devices support single-supply operation from +10 V to +30 V in addition to dual-supply operation, per the Analog Devices datasheet.
What is the off-isolation specification for the ADG406BP and ADG407BP?
Both devices specify a typical off-isolation of 68 dB at 1 MHz, per the Analog Devices datasheet.
Are the ADG406BP and ADG407BP controlled by the same digital interface?
Both devices use TTL/CMOS-compatible logic inputs. The ADG406BP uses 3 address bits to select 1 of 8 channels, while the ADG407BP uses 2 address bits plus a separate enable per multiplexer to select 1 of 4 channels in each of the two banks. The logic control scheme differs and must be accounted for in the design.
