Product details
Overview
ADG508FBRNZ-REEL7 from Analog Devices is an 8-channel single-ended fault-protected CMOS analog multiplexer with break-before-make switching, 270 Ω typical on-resistance, −40 V to +55 V continuous overvoltage tolerance, and 230 ns maximum tON. It routes one of eight analog inputs to a common output under 3-bit binary address control (A0–A2) and enables system-level protection in industrial sensor signal conditioning.
For engineers reviewing the ADG508FBRNZ-REEL7 datasheet, ADG508FBRNZ-REEL7 pinout, ADG508FBRNZ-REEL7 application, or ADG508FBRNZ-REEL7 equivalent, this page delivers verified specifications, SOIC_N package mapping, fault-protection behavior under power-off conditions, and real-world multiplexer selection guidance for high-reliability analog front-ends.
Technical Context
The ADG508FBRNZ-REEL7 implements a series n-p-n MOSFET channel architecture that clamps overvoltage inputs by saturating individual transistors-enabling −40 V to +55 V fault tolerance regardless of supply state. Its break-before-make timing (tOPEN ≥ 60 ns) prevents momentary shorting between channels during address transitions.
With dual ±15 V supplies, it delivers 390 Ω max on-resistance across −10 V to +10 V analog signals at 1 mA, 0.6 %/°C RON drift, and <1 nA off-leakage (−40°C to +85°C). Digital inputs are TTL/CMOS compatible (VINH ≥ 2.4 V, VINL ≤ 0.8 V), and EN enables full-device disable with open-circuit isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | 8 single-ended inputs to 1 common output - supports multi-sensor scanning without external buffering. |
| Fault Protection Range | −40 V to +55 V continuous - protects against sensor wiring faults, ESD transients, and power-rail collapse. |
| On-Resistance (RON) | 270 Ω typical / 390 Ω max - ensures minimal gain error and signal attenuation in precision measurement paths. |
| Switching Time (tON) | 230 ns maximum - enables sub-microsecond channel settling for high-throughput data acquisition. |
| Off-Leakage Current | ±1 nA max at −40°C to +85°C - preserves accuracy in high-impedance source applications (e.g., thermocouples). |
| Supply Range | ±15 V ±10% dual supply - supports legacy industrial rails; GND reference allows single-supply adaptation via VSS = GND. |
| Digital Interface | TTL/CMOS-compatible EN, A0–A2 - interfaces directly with microcontrollers and FPGAs without level-shifting. |
Pinout & Package
ADG508FBRNZ-REEL7 is housed in a 16-lead narrow-body SOIC (SOIC_N, R-16) package, 10.00 mm × 4.00 mm × 1.50 mm, RoHS-compliant, tape-and-reel format (REEL7).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A2 | 3-bit binary address inputs | Selects one of eight analog channels (S1–S8); logic levels define active channel without internal decoding delay. |
| EN | Active-high enable input | Disables all switches when low; eliminates crosstalk and leakage in standby mode. |
| S1–S8 | Source terminals (analog inputs/outputs) | Bi-directional pins - accept sensor signals or drive downstream circuitry; each protected independently. |
| D | Common drain terminal (analog output/input) | Single bidirectional node shared across all channels; connects to ADC input or amplifier stage. |
| VDD, VSS | Positive/negative supply rails | Support ±15 V operation; VSS may be tied to GND in single-supply configurations with reduced analog range. |
| GND | Ground reference | 0 V reference for digital logic and supply decoupling; separate from analog ground but must be low-impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Fault-tolerant channel architecture | Series n-p-n MOSFET structure limits fault current and clamps overvoltage without latch-up - survives −40 V/+55 V continuously. |
| Power-off protection | Leakage <2 μA with VDD/VSS = 0 V - isolates sensors and downstream circuitry during brownout or shutdown. |
| Break-before-make switching | tOPEN ≥ 60 ns guarantees no overlap between channel conduction - prevents signal shorting during address changes. |
| Low charge injection | 15 pC typical - minimizes voltage glitch at D terminal during switching, critical for sample-and-hold stability. |
| Latch-up immunity | Trench-isolated process - eliminates parasitic SCR formation, enabling robust operation in noisy industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG508FBRUZ-REEL7 | TSSOP-16 package (4.4 mm × 3.0 mm); same electrical specs and fault rating. | Better thermal performance (θJA = 112°C/W vs. 77°C/W) and smaller footprint - preferred for space-constrained PCBs. | Select when board area or thermal dissipation is critical; requires layout revision due to different land pattern. |
| ADG509FBRNZ-REEL7 | 4-channel differential configuration; 2-bit address (A0/A1); identical fault protection and RON. | Optimized for differential sensor pairs (e.g., bridge transducers); not pin-compatible - requires redesign of address logic and routing. | Choose for differential signal integrity needs; not a drop-in replacement but shares same reliability architecture. |

FAQ
What is the maximum continuous overvoltage rating for ADG508FBRNZ-REEL7?
The ADG508FBRNZ-REEL7 withstands continuous analog input voltages from −40 V to +55 V, regardless of whether power supplies are active or off. This rating is validated under worst-case conditions including power loss, ensuring protection for both the multiplexer and upstream sensors or downstream circuitry.
Does ADG508FBRNZ-REEL7 support single-supply operation?
Yes, ADG508FBRNZ-REEL7 supports single-supply operation by connecting VSS to GND. In this configuration, the analog input range reduces to 1.4 V above GND and 1.4 V below VDD (e.g., 0 V to +13.6 V with +15 V supply), maintaining full fault protection within those bounds.
What is the guaranteed break-before-make timing for ADG508FBRNZ-REEL7?
The ADG508FBRNZ-REEL7 guarantees tOPEN ≥ 60 ns minimum under RL = 1 kΩ, CL = 35 pF, and VS = 5 V conditions. This ensures no overlap between channel conduction during address transitions, preventing transient short circuits in multi-source analog systems.
How does ADG508FBRNZ-REEL7 behave when power supplies are off?
When VDD and VSS are at 0 V, the ADG508FBRNZ-REEL7 presents an open circuit at all S and D terminals, with leakage current limited to ±2 μA maximum. This isolates connected sensors and downstream circuitry, preserving system integrity during power-down or brownout events.
Is ADG508FBRNZ-REEL7 pin-compatible with standard ADG508 variants?
Yes, ADG508FBRNZ-REEL7 shares identical pinout, function mapping, and electrical behavior with non-fault-protected ADG508B variants in SOIC_N packages. However, its fault-protection architecture adds internal series MOSFETs - no layout change is needed, but system-level fault resilience improves significantly.
