Product details
Overview
ADG5412FBCPZ-RL7 from Analog Devices is a fault-protected quad SPST analog switch with 10 Ω typical on-resistance, ±55 V overvoltage protection on source pins, and integrated fault detection flag (FF) output. It operates from ±5 V to ±22 V dual supplies or 8 V to 44 V single supply, and is designed for high-reliability signal routing in industrial data acquisition systems where input transients exceed rail limits.
For engineers reviewing the ADG5412FBCPZ-RL7 datasheet, ADG5412FBCPZ-RL7 pinout, ADG5412FBCPZ-RL7 application, or ADG5412FBCPZ-RL7 equivalent, key selection criteria include overvoltage fault response time (460 ns typ), on-resistance flatness (0.6 Ω typ), THD+N (0.0015% typ at ±15 V), and latch-up immunity under all conditions - critical for process control I/O modules and automatic test equipment.
Technical Context
The ADG5412FBCPZ-RL7 implements trench-isolated, fault-protected switch architecture with independent channel control. Each of its four SPST switches turns on with logic-high input and supports bidirectional signal flow across the full VSS-to-VDD analog range, including operation with unpowered supplies.
Fault detection is implemented via voltage threshold monitoring (VT = 0.7 V typ) on each Sx pin: when any source voltage exceeds VDD or falls below VSS by VT, the affected channel disables and asserts FF low. The device maintains high-impedance state during power-off and delivers 5.5 kV HBM ESD rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance (RON) | 10 Ω typical at ±15 V - enables low-insertion-loss signal routing in precision gain-switching circuits. |
| Overvoltage Protection Range | −55 V to +55 V on Sx pins - blocks hazardous transients without external clamping in field-connected analog inputs. |
| Overvoltage Response Time | 460 ns typical - ensures fast channel disable before downstream circuit damage during surge events. |
| THD + Noise | 0.0015% typical at ±15 V, 20 Hz–20 kHz - preserves signal fidelity in high-resolution data acquisition paths. |
| Fault Flag (FF) Output | Active-low digital flag indicating any channel fault - simplifies system-level diagnostics without host MCU polling overhead. |
| Supply Range | ±5 V to ±22 V dual or 8 V to 44 V single - supports wide-range industrial power architectures including ±15 V and +36 V rails. |
| Operating Temperature | −40°C to +125°C - qualified for use in harsh environments such as avionics and distributed control systems. |
Pinout & Package
ADG5412FBCPZ-RL7 is packaged in a 16-lead LFCSP (3 mm × 3 mm, 0.5 mm pitch) with exposed pad for thermal performance. Pin numbering follows standard LFCSP orientation (pin 1 marked).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control input | 3 V–compatible logic inputs; high = switch closed, low = open - enables direct interface with microcontrollers and FPGAs. |
| S1–S4 | Protected source terminal | Overvoltage-tolerant analog I/O node; withstands −55 V to +55 V relative to ground even when unpowered. |
| D1–D4 | Drain terminal | Standard analog I/O node; clamped to VSS −0.7 V / VDD +0.7 V - requires external protection if exposed to overvoltage. |
| VSS | Negative supply rail | Most negative power potential; must be connected for proper fault protection and switch operation. |
| GND | Ground reference | 0 V reference for digital logic and fault flag; electrically isolated from analog signal ground in mixed-signal layouts. |
| FF | Fault flag output | Open-drain active-low output signaling any channel overvoltage event - requires external pull-up for system interrupt generation. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage protection on Sx pins | −55 V to +55 V tolerance with automatic channel disable - eliminates need for external TVS diodes in sensor front-ends. |
| Power-off protection | Maintains high-impedance state with floating or grounded supplies - prevents back-driving and signal leakage during brownout or shutdown. |
| Intelligent fault detection | Dedicated FF pin provides immediate system-level alert on first fault occurrence - reduces diagnostic latency versus software-based monitoring. |
| Low on-resistance flatness | 0.6 Ω typical variation across signal range - minimizes gain error and distortion in programmable-gain amplifier and multiplexer applications. |
| Latch-up immunity | Guaranteed immune under all voltage, temperature, and transient conditions - ensures robust operation in noisy industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG5412BRUZ | TSSOP-16 package; higher θJA (112.6°C/W vs. 30.4°C/W); identical electrical specs and fault behavior. | Better suited for prototyping and lower-power PCBs where thermal dissipation is not constrained. | Select ADG5412BRUZ for manual assembly or space-tolerant designs; ADG5412FBCPZ-RL7 preferred for high-density, thermally demanding industrial modules. |
| MAX14662ETA+ | Lower overvoltage rating (±40 V); no integrated fault flag; 4.5 Ω RON; operates up to +65°C only. | Targeted at commercial-grade portable instrumentation with tighter size constraints but relaxed environmental requirements. | Choose MAX14662ETA+ only when overvoltage exposure is limited and extended temperature operation is unnecessary. |

FAQ
What is the maximum overvoltage the ADG5412FBCPZ-RL7 can withstand on its Sx pins?
The ADG5412FBCPZ-RL7 withstands −55 V to +55 V on its Sx pins relative to ground, both during powered and unpowered states. This protection is enabled by internal fault circuitry that disables the channel and asserts the FF pin low when the threshold voltage (VT = 0.7 V typ) is exceeded. The specification is guaranteed per Analog Devices Rev. C datasheet Table 6 and applies regardless of supply rail status.
Does the ADG5412FBCPZ-RL7 require external pull-up on the FF pin?
Yes, the FF pin is an open-drain output and requires an external pull-up resistor (typically 1 kΩ to VDD or IOVDD) to generate a valid logic-high signal during normal operation. When any Sx pin experiences overvoltage, FF pulls low. The ADG5412FBCPZ-RL7 datasheet Figure 43–45 and Table 1–4 confirm this behavior and specify tDIGRESP (85 ns typ) and tDIGREC (60 µs typ) timing with RPULLUP = 1 kΩ.
Can the ADG5412FBCPZ-RL7 operate from a single 12 V supply?
Yes, the ADG5412FBCPZ-RL7 supports 12 V single-supply operation (VDD = 12 V, VSS = 0 V), with full functionality including fault protection and FF reporting. Per datasheet Table 3, RON is 22 Ω typ (0 V–10 V range) and 10 Ω typ (3.5 V–8.5 V range), and overvoltage response time remains within 720 ns max. The device is fully specified at this condition.
What is the thermal performance difference between ADG5412FBCPZ-RL7 and ADG5412BRUZ?
The ADG5412FBCPZ-RL7 in 16-lead LFCSP has θJA = 30.4°C/W (4-layer board), while the ADG5412BRUZ in TSSOP has θJA = 112.6°C/W. At 1.2 mA IDD in fault mode, ADG5412FBCPZ-RL7 junction rise is ~36°C vs. ~135°C for ADG5412BRUZ - making the LFCSP version essential for high-density, thermally constrained industrial PCBs where ambient exceeds 85°C.
Is the ADG5412FBCPZ-RL7 latch-up immune under all operating conditions?
Yes, the ADG5412FBCPZ-RL7 is explicitly rated as latch-up immune under any circumstance per datasheet Features section and Table 6 Absolute Maximum Ratings. This immunity is achieved via trench isolation technology and is guaranteed across −40°C to +125°C, all supply voltages (±5 V to ±22 V), and transient overvoltage events up to ±55 V - a key differentiator versus standard CMOS switches.
