Product details
Overview
ADG509FBRNZ-REEL7 from Analog Devices is a fault-protected 4-channel differential analog multiplexer with ±15 V dual-supply operation, 270 Ω typical on-resistance, 230 ns maximum tON, −40 V to +55 V continuous overvoltage tolerance, and break-before-make switching. It routes one of four differential input pairs to a common differential output in industrial data acquisition systems where sensor overvoltage events are possible.
For engineers reviewing the ADG509FBRNZ-REEL7 datasheet, ADG509FBRNZ-REEL7 pinout, ADG509FBRNZ-REEL7 application, or ADG509FBRNZ-REEL7 equivalent, this page delivers verified specifications, SOIC_N package details, fault-protection behavior under power-off conditions, and real-world selection guidance for high-reliability analog signal routing.
Technical Context
The ADG509FBRNZ-REEL7 implements a series n-channel/p-channel/n-channel MOSFET architecture per channel, enabling clamping and current limiting during overvoltage faults. Its 2-bit address decoding (A0, A1) selects one of four differential switch pairs, while EN enables/disables all channels simultaneously.
It operates with true break-before-make timing (tOPEN ≥ 40 ns min), guarantees latch-up immunity via trench isolation, and maintains <±1 nA leakage during power-off faults (VS = ±25 V). Analog signal range is VSS + 1.4 V to VDD − 1.4 V (open-circuit) with ±10 V loaded compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | VSS + 1.4 V to VDD − 1.4 V (open circuit); supports ±10 V signals with 1 mA load |
| RON (typ/max) | 270 Ω typical / 390 Ω maximum at ±10 V; ensures low insertion loss in precision signal paths |
| tON / tOFF (max) | 230 ns / 130 ns maximum; enables sub-microsecond channel switching in fast-scanning systems |
| Fault Tolerance | −40 V to +55 V continuous overvoltage with power on or off; protects sensors and downstream circuitry |
| Leakage (Fault, PS Off) | ±1 nA typical / ±2 μA maximum; prevents erroneous biasing of high-impedance sources during fault |
| Off Isolation | 93 dB typical at 100 kHz; suppresses crosstalk between inactive and active differential channels |
| Digital Compatibility | TTL/CMOS inputs; VINH ≥ 2.4 V, VINL ≤ 0.8 V; interfaces directly with microcontrollers and FPGAs |
Pinout & Package
ADG509FBRNZ-REEL7 is supplied in a 16-lead SOIC_N (R-16) package, 7.5 mm × 4.4 mm body, 1.27 mm pitch, RoHS-compliant, tape-and-reel format (REEL7).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A0, A1 | 2-bit binary address inputs selecting one of four differential channel pairs |
| 2 | EN | Active-high enable; disables all switches when low, preventing unintended conduction |
| 3, 14 | VSS, VDD | Negative/positive supply rails; support ±15 V dual supply or single-supply operation with VSS = GND |
| 4, 13 | S1A, S1B | Differential source pair for Channel 1; bidirectional signal path with matched RON |
| 5, 12 | S2A, S2B | Differential source pair for Channel 2; identical electrical characteristics to S1A/S1B |
| 6, 11 | S3A, S3B | Differential source pair for Channel 3; maintains <3% RON match across all channels |
| 7, 10 | S4A, S4B | Differential source pair for Channel 4; supports full ±40 V to +55 V fault range |
| 8, 9 | DA, DB | Differential drain outputs; routed to common destination with break-before-make timing |
| 15 | GND | Ground reference; decoupling required near VDD/VSS pins for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Fault protection with power off | Withstands −40 V to +55 V overvoltage and limits leakage to <2 μA even when VDD/VSS = 0 V |
| Break-before-make switching | Guaranteed tOPEN ≥ 40 ns minimum prevents momentary shorting between differential source pairs |
| Latch-up proof construction | Trench isolation separates p- and n-channel MOSFETs, eliminating risk of destructive latch-up |
| Low charge injection | 15 pC typical; minimizes voltage glitch on high-impedance nodes during channel switching |
| Low power dissipation | 3.3 mW maximum at ±15 V; reduces thermal drift and simplifies thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fault-protected analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG509FBRUZ-REEL7 | TSSOP-16 package (4.4 mm × 3.0 mm); 112°C/W θJA vs. SOIC_N's 77°C/W | Better suited for space-constrained portable instruments; higher thermal resistance requires derating above 70°C ambient | Select for compact layouts where board area is critical and thermal load is moderate. |
| MAX4619ESE+ | Single-supply only (2.7 V to 5.5 V); no dual-supply or ±15 V capability; 400 Ω RON max | Designed for low-voltage, low-power embedded systems-not suitable for industrial ±10 V signal ranges | Choose only for battery-powered 3.3 V systems requiring minimal quiescent current (1 μA), not for fault-tolerant industrial use. |
Compared with ADG509FBRUZ-REEL7, ADG509FBRNZ-REEL7 offers superior thermal performance and mechanical robustness in SOIC_N; versus MAX4619ESE+, it delivers full industrial fault protection and bipolar signal handling-neither is pin-compatible, and both require layout changes.

FAQ
What is the maximum continuous overvoltage rating for ADG509FBRNZ-REEL7 with power supplies off?
ADG509FBRNZ-REEL7 withstands −40 V to +55 V continuous overvoltage even when VDD and VSS are disconnected. Under these conditions, source leakage remains ≤±2 μA, protecting both upstream sensors and downstream circuitry without external components.
Does ADG509FBRNZ-REEL7 support single-supply operation?
Yes, ADG509FBRNZ-REEL7 supports single-supply operation: connect VSS to GND and apply VDD between +5 V and +15 V. The analog input range becomes 1.4 V to (VDD − 1.4 V) open-circuit, maintaining full fault protection within rated limits.
What is the guaranteed break-before-make time for ADG509FBRNZ-REEL7?
ADG509FBRNZ-REEL7 guarantees tOPEN ≥ 40 ns minimum (measured between 80% points of adjacent switch transitions). This ensures no momentary shorting between differential source pairs during address changes, critical for protecting sensitive signal sources.
How does the series n-p-n MOSFET structure in ADG509FBRNZ-REEL7 enable fault protection?
The ADG509FBRNZ-REEL7 uses three MOSFETs per channel (n-p-n) in series. During overvoltage, either the p-channel or an n-channel device saturates, limiting current flow. This architecture clamps the output and restricts leakage to nanoampere levels-regardless of whether power is applied.
Is ADG509FBRNZ-REEL7 pin-compatible with ADG508FBRNZ-REEL7?
No. ADG509FBRNZ-REEL7 is a 4-channel differential multiplexer with A0/A1 addressing and SxA/SxB/DA/DB pins; ADG508FBRNZ-REEL7 is an 8-channel single-ended device with A0/A1/A2 and S1–S8/D pins. Pin functions, count, and logic mapping differ fundamentally-PCB redesign is required for substitution.
