Product details
Overview
ADG5436FBCPZ-RL7 from Analog Devices is a fault-protected dual SPDT analog switch IC with 10 Ω typical on-resistance, ±55 V overvoltage protection on source pins, and integrated fault detection with interrupt flag output. It operates from ±5 V to ±22 V dual supplies or 8 V to 44 V single supply, and is used in industrial data acquisition systems where signal integrity must be preserved under fault conditions.
For engineers reviewing the ADG5436FBCPZ-RL7 datasheet, ADG5436FBCPZ-RL7 pinout, ADG5436FBCPZ-RL7 application, or ADG5436FBCPZ-RL7 equivalent, key selection criteria include its trench-isolated fault protection architecture, break-before-make switching action, low on-resistance flatness (≤0.5 Ω), 125°C junction-rated operation, and compatibility with 3 V logic inputs across full supply range.
Technical Context
The ADG5436FBCPZ-RL7 implements two independent SPDT switches with EN-controlled global disable and DR-configurable fault response (high-impedance or rail-pull). Its trench isolation prevents latch-up under overvoltage stress, and each channel supports bidirectional conduction with VSS-to-VDD analog signal range.
Fault detection triggers when any Sxx pin exceeds VDD or VSS by >0.7 V (typical VT), asserting the FAULT pin and disabling the affected channel. The interrupt flag provides digital status indication with <115 ns response time, while overvoltage recovery completes within 1.7 µs at ±20 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance (RON) | 10 Ω typical - enables low insertion loss and minimal gain error in precision signal paths |
| On-Resistance Flatness | ≤0.5 Ω max - ensures excellent THD+N (<0.001%) and linearity over wide signal range |
| Fault Protection Range | ±55 V on Sxx pins - blocks hazardous transients during powered/unpowered states without external clamps |
| Supply Range | ±5 V to ±22 V dual or 8 V to 44 V single - supports legacy ±15 V, ±20 V, +12 V, and +36 V industrial rails |
| Interrupt Response Time | 85–115 ns - enables fast system-level fault logging and safety shutdown coordination |
| Charge Injection | −737 pC typ (±20 V) - minimized settling error in multiplexed ADC front-ends |
| ESD Rating | 6 kV HBM - robust handling in manufacturing and field-repair environments |
Pinout & Package
The ADG5436FBCPZ-RL7 is housed in a 16-lead LFCSP (3 mm × 3 mm, 0.5 mm pitch) package with exposed thermal pad. Pin 1 marked via top-side dot; recommended solder profile per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | 3 V logic-compatible; control S1A/S1B and S2A/S2B switch positions independently |
| EN | Global enable | Active-high; disables both switches simultaneously when low |
| S1A, S1B, S2A, S2B | Analog source inputs | Fault-protected inputs; tolerate −55 V to +55 V relative to GND regardless of power state |
| D1, D2 | Analog drain outputs | Switched outputs; behavior under fault depends on DR pin state (float/high = high-Z; low = rail pull) |
| DR1, DR2 | Fault response control | Per-channel configuration for drain behavior during overvoltage events |
| FAULT | Open-drain fault indicator | Asserts low when any Sxx pin exceeds VT; requires external pull-up for logic-level interface |
| VDD, VSS, GND | Power and reference | VDD/VSS define analog signal range; GND is functional ground reference for digital and fault logic |
Key Features
| Feature | Design Value |
|---|---|
| Trench-isolated fault protection | Guarantees latch-up immunity under ±55 V source faults, eliminating need for external protection circuitry |
| Break-before-make switching | Ensures no momentary short between S1A/S1B or S2A/S2B during transition - critical for multiplexer safety |
| Known-state logic on power-up | Switches remain off and high-impedance until valid EN and IN signals are applied - prevents undefined signal routing |
| Wide supply flexibility | Single-supply (8–44 V) and dual-supply (±5–±22 V) operation simplifies integration into mixed-rail industrial systems |
| Low charge injection | −737 pC typ at ±20 V enables accurate sampling in high-resolution, multiplexed data acquisition channels |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG5436BCPZ-RL7 | Lacks fault detection circuitry and FAULT/DR pins; identical RON, flatness, and supply range | No overvoltage status reporting; unsuitable where system-level fault logging or autonomous shutdown is required | Select ADG5436FBCPZ-RL7 when fault visibility and controlled response are mandatory; use ADG5436BCPZ-RL7 only in cost-sensitive, non-safety-critical paths |
| MAX14662ETE+ | Single SPDT, 4.5 Ω RON, ±60 V fault protection, but no interrupt flag or DR control | Half the channel count; lower RON but no digital fault signaling - requires external monitoring circuitry | Choose ADG5436FBCPZ-RL7 for dual-channel, self-reporting protection; MAX14662ETE+ only if single-channel + lower RON suffices and FAULT pin is not needed |
Compared with ADG5436BCPZ-RL7 and MAX14662ETE+, the ADG5436FBCPZ-RL7 uniquely delivers dual SPDT topology with integrated fault detection, interrupt flag, and per-channel DR configurability - enabling autonomous, observable protection without external components or firmware overhead.

FAQ
What is the maximum continuous current per channel for ADG5436FBCPZ-RL7?
The ADG5436FBCPZ-RL7 supports up to 207 mA continuous current per channel at 25°C when using the 16-lead LFCSP package (θJA = 30.4°C/W), derating to 68 mA at +125°C ambient. This rating applies to Sxx or Dx pins with signals between VSS + 4.5 V and VDD − 4.5 V; full-range operation (VSS to VDD) reduces max current to 161 mA at 25°C. These values are specified in Table 5 of the ADG5436F datasheet Rev. C.
Does ADG5436FBCPZ-RL7 require external pull-up resistors on the FAULT pin?
Yes, the FAULT pin on ADG5436FBCPZ-RL7 is an open-drain output and requires an external pull-up resistor to a logic-compatible voltage (e.g., 3.3 V or 5 V) to generate a valid high-level signal. Typical values range from 1 kΩ to 10 kΩ depending on bus capacitance and required rise time; Figure 43 in the ADG5436F datasheet shows a 1 kΩ pull-up with 600 ns recovery time.
Can ADG5436FBCPZ-RL7 operate with only a single supply?
Yes, ADG5436FBCPZ-RL7 supports single-supply operation from 8 V to 44 V (VDD to GND), with analog signal range from 0 V to VDD. It is fully specified at +12 V and +36 V single-supply conditions, maintaining 10 Ω typical RON and ±55 V fault protection on source pins - making it suitable for battery-powered or unipolar industrial systems.
How does the DR pin affect fault behavior in ADG5436FBCPZ-RL7?
The DR pin configures drain behavior during overvoltage events: when DR is pulled low, the affected Dx pin pulls to the exceeded rail (VDD or VSS); when DR is floating or pulled high (>2 V), Dx goes high-impedance. This allows system designers to choose between active clamping or isolation - a key differentiator from non-F variants like ADG5436BCPZ-RL7, which lack DR control.
Is ADG5436FBCPZ-RL7 compatible with 3 V logic inputs across all supply conditions?
Yes, ADG5436FBCPZ-RL7 guarantees 3 V logic compatibility for IN1, IN2, and EN inputs across its entire operating supply range (±5 V to ±22 V dual or 8 V to 44 V single). Input thresholds are fixed at VINH ≥ 2.0 V and VINL ≤ 0.8 V, with leakage <1.2 µA, ensuring reliable interfacing with microcontrollers, FPGAs, and ASICs without level-shifting circuitry.
