Key electrical and mechanical differences between the two devices
| Parameter | ADG409BR | ADG409BR-REEL | Why it matters |
|---|---|---|---|
| Number of Channels | 2 (differential 4:1) | 2 (differential 4:1) | Defines how many independent signal paths the multiplexer can switch; must match for functional substitutability. |
| Switch Configuration | 4:1 Multiplexer (differential) | 4:1 Multiplexer (differential) | Determines the switching topology; identical configuration ensures the same routing behavior in a circuit. |
| On-Resistance (Typical) | 100 Ω | 100 Ω | Affects signal attenuation and voltage drop across the switch; matching values preserve signal integrity. |
| Supply Voltage Range | ±15 V dual / +12 V single | ±15 V dual / +12 V single | Must be compatible with the system power rails; identical range ensures drop-in compatibility. |
| Package / Mounting | 16-Lead SOIC (surface mount) | 16-Lead SOIC (surface mount) | Physical footprint and mounting style must match for PCB compatibility. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures the device operates reliably within the application's environmental conditions. |
| Packaging / Delivery Form | Tube / individual | Tape and Reel | Affects manufacturing handling and assembly line compatibility; the reel version suits automated pick-and-place production. |
| Channel-to-Channel Matching | Typically < 5 Ω | Typically < 5 Ω | Matching between channels minimizes differential error in signal switching; identical values preserve accuracy. |
| Switching Time (Typical) | ~150 ns | ~150 ns | Determines how fast the multiplexer can route signals; matching timing ensures equivalent dynamic performance. |

Frequently asked questions
What is the difference between ADG409BR and ADG409BR-REEL?
The ADG409BR and ADG409BR-REEL refer to the same ADG409 device in a 16-lead SOIC package. The "-REEL" suffix designates tape-and-reel packaging for automated assembly, while the base ADG409BR part number typically denotes tube or tray packaging. Electrical and functional specifications are identical.
Are the ADG409BR and ADG409BR-REEL electrically identical?
Yes. Both part numbers describe the same ADG409 die and package; the only documented difference is the shipping/packaging format. Datasheet parameters such as on-resistance, leakage, switching times, and supply range apply equally to both.
What are the key specifications of the ADG409?
The ADG409 is a differential 4-channel CMOS analog multiplexer. Verified datasheet parameters include dual-supply operation of ±15 V (or single +12 V), low on-resistance (typically 100 Ω), fast switching times (tON/tOFF in the tens of nanoseconds), low charge injection, and TTL/CMOS-compatible logic inputs. It is specified for the commercial temperature range and offered in a 16-lead SOIC package.
Can ADG409BR and ADG409BR-REEL be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable because they share the same die, package, and pinout. The choice between them is driven by assembly method: -REEL for pick-and-place reel-fed production, base part number for tube-based or prototype handling.
What package does the ADG409BR use?
The ADG409BR is supplied in a 16-lead SOIC (small outline integrated circuit) package, designated "R" in the ordering code. The same package applies to ADG409BR-REEL.
Which logic levels are compatible with the ADG409 digital inputs?
The ADG409 digital control inputs (A0, A1, EN) are TTL and CMOS compatible, allowing direct interfacing with standard 5 V logic families without external level shifting, per the manufacturer datasheet.
Does the -REEL suffix affect moisture sensitivity or handling requirements?
No. Moisture sensitivity level (MSL) and handling requirements are determined by the package and are the same for ADG409BR and ADG409BR-REEL. Both use the identical 16-lead SOIC body; reel packaging does not change the MSL classification.
