Product details
Overview
ADG408BR-REEL7 from Analog Devices is an 8-channel single-ended analog multiplexer IC designed for precision signal routing in data acquisition and test systems. It features 100 Ω maximum on-resistance, ±15 V dual-supply operation (or 12 V single supply), break-before-make switching, and 130 ns typical transition time. It operates across −40°C to +85°C and is used in audio/video routing and battery-powered instrumentation.
For engineers reviewing the ADG408BR-REEL7 datasheet, ADG408BR-REEL7 pinout, ADG408BR-REEL7 application, or ADG408BR-REEL7 equivalent, key selection criteria include on-resistance flatness over signal range, low charge injection (5 pC typ in single-supply mode), off-isolation (−75 dB typ), and compatibility with 3.3 V/5 V logic control levels.
Technical Context
The ADG408BR-REEL7 implements a 1-of-8 decoder architecture controlled by three binary address lines (A0–A2) and an active-high enable (EN). All eight source terminals (S1–S8) are bidirectional and support rail-to-rail analog signals from VSS to VDD in dual-supply mode or 0 V to VDD in single-supply mode.
Its LC2MOS process ensures low power consumption (<5 μA max quiescent current when disabled), fast switching with guaranteed break-before-make timing (tOPEN ≥10 ns), and minimal channel crosstalk (85 dB typ at 100 kHz). The device blocks signals up to ±15 V in off state and exhibits <15 Ω RON matching (∆RON) between channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 8 single-ended analog switches - enables flexible signal routing from one of eight inputs to a common drain (D). |
| On-resistance (RON) | 90 Ω typical at VDD = 12 V, VSS = 0 V - ensures minimal signal attenuation and gain error in precision measurement paths. |
| Signal range | 0 V to VDD (single supply) or VSS to VDD (dual supply) - supports unipolar and bipolar analog signals without level-shifting. |
| Switching speed | 130 ns typical tTRANSITION - enables high-throughput sampling in multichannel data acquisition systems. |
| Off isolation | −75 dB typical at 100 kHz - suppresses leakage between inactive channels in sensitive mixed-signal environments. |
| Charge injection | 5 pC typical (single supply) - minimizes voltage glitches at the output during digital address changes, critical for sample-and-hold accuracy. |
| Supply current | 5 μA maximum IDD when disabled - extends battery life in portable instrumentation and sensor interfaces. |
Pinout & Package
ADG408BR-REEL7 is housed in a 16-lead narrow-body SOIC (SOIC_N, package option R-16), 3.9 mm × 9.9 mm body size, 1.27 mm lead pitch, JEDEC MS-012-AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A0) | Binary address input | LSB of 3-bit channel select code; determines which Sx terminal connects to D when EN = high. |
| 2 (EN) | Active-high enable | Disables all switches when low; required for power gating and system-level channel arbitration. |
| 3 (VSS) | Negative supply rail | Connects to ground in single-supply mode; sets lower bound of analog signal range in dual-supply operation. |
| 4–11 (S1–S8) | Analog source terminals | Bidirectional I/O pins; each can serve as input or output depending on signal flow direction in the application. |
| 8 (D) | Common drain/output | Single bidirectional terminal shared by all eight channels; connects to ADC input, amplifier, or signal processor. |
| 13 (VDD) | Positive supply rail | Supports 5 V to 15 V operation; defines upper limit of analog signal swing and powers internal logic. |
| 14 (GND) | Digital/analog reference | Ground return for digital control signals and substrate reference; requires low-impedance connection to minimize noise coupling. |
| 15 (A2) | Binary address input | MSB of 3-bit channel select code; together with A0/A1, fully decodes S1–S8 selection. |
| 16 (A1) | Binary address input | Middle bit of 3-bit channel select code; completes full 8-channel addressing capability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Operates with analog signals extending from VSS to VDD - eliminates need for external level shifters in bipolar front-end designs. |
| Break-before-make action | tOPEN ≥10 ns guarantees no momentary short between channels during switching - prevents signal corruption in multiplexed sensor arrays. |
| Low charge injection | 5 pC typical (single supply) - reduces settling error and hold-step transient in precision sample-and-hold circuits. |
| Plug-in DG408 replacement | PIN-compatible upgrade with improved RON, lower leakage, and enhanced ESD robustness - enables drop-in reliability improvement in legacy designs. |
| Wide supply flexibility | Functional from 5 V to 15 V single supply or ±5 V to ±15 V dual supply - simplifies integration across industrial, medical, and test equipment platforms. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ-REEL7 | RoHS-compliant variant with same SOIC_N package, identical electrical specs, and green molding compound. | No functional difference; selected where lead-free compliance is mandated for final product certification. | Choose ADG408BRZ-REEL7 for new designs requiring RoHS-6 or China RoHS compliance; ADG408BR-REEL7 remains valid for legacy builds. |
| MAX4617ESE+ | 8-channel CMOS mux with 60 Ω max RON, but only supports 5 V single supply and lacks dual-supply capability. | Suitable for low-voltage embedded systems but incompatible with ±12 V or ±15 V signal conditioning stages. | Select MAX4617ESE+ only when operating exclusively from 5 V and rail-to-rail bipolar signal handling is not required. |
Compared with ADG408BR-REEL7, ADG408BRZ-REEL7 offers identical performance with environmental compliance, while MAX4617ESE+ trades dual-supply flexibility for lower on-resistance in 5 V-only applications - making ADG408BR-REEL7 optimal for wide-swing, mixed-voltage test and measurement systems.

FAQ
What is the maximum supply voltage rating for ADG408BR-REEL7?
The ADG408BR-REEL7 has an absolute maximum VDD to VSS rating of 44 V. It operates reliably across dual supplies from ±5 V to ±15 V or single supplies from 5 V to 15 V. Exceeding these limits risks permanent damage per Table 3 in the Rev. D datasheet.
Does ADG408BR-REEL7 support rail-to-rail analog signal switching?
Yes, ADG408BR-REEL7 supports rail-to-rail analog signal switching: its analog signal range extends from VSS to VDD in dual-supply mode and from 0 V to VDD in single-supply mode. This allows full utilization of the supply rails without clipping or level-shifting circuitry.
What is the function of the EN pin on ADG408BR-REEL7?
The EN (Enable) pin on ADG408BR-REEL7 is an active-high digital input. When low, all eight channels are switched off regardless of A0–A2 states. When high, the 3-bit address selects one of S1–S8 to connect to D. This enables system-level power gating and channel arbitration.
Can ADG408BR-REEL7 be used with 3.3 V logic control signals?
Yes, ADG408BR-REEL7 accepts 3.3 V logic levels: its digital inputs require only VINH ≥ 2.4 V (min) and VINL ≤ 0.8 V (max), fully compatible with standard 3.3 V CMOS outputs. No level translation is needed when driven by microcontrollers or FPGAs operating at 3.3 V.
How does ADG408BR-REEL7 handle switching transients during channel changes?
ADG408BR-REEL7 minimizes switching transients via break-before-make action (tOPEN ≥10 ns) and low charge injection (5 pC typical in single-supply mode). These features prevent momentary shorts and reduce output glitches - critical for maintaining accuracy in sample-and-hold and precision ADC front ends.
