Product details
Overview
ADG1434YRUZ from Analog Devices is a quad SPDT analog switch in the iCMOS® family, designed for high-voltage signal routing in precision data acquisition and industrial control systems. It delivers 4.7 Ω max on-resistance at ±15 V, 0.5 Ω on-resistance flatness, rail-to-rail operation, break-before-make switching, and supports ±15 V / +12 V / ±5 V supplies with 3 V logic compatibility.
For engineers reviewing the ADG1434YRUZ datasheet, ADG1434YRUZ pinout, ADG1434YRUZ application, or ADG1434YRUZ equivalent, this page provides verified specifications, package-confirmed pin functions, real-world use cases in medical instrumentation and ATE, and two validated alternative parts with documented functional and application differences.
Technical Context
The ADG1434YRUZ implements four independent SPDT switches using Analog Devices' proprietary iCMOS® process-integrating high-voltage CMOS and bipolar technologies to achieve 33 V tolerant operation in compact 20-lead TSSOP (RU-20) and 4 mm × 4 mm LFCSP packages. Its EN input enables global disable, and all channels enforce break-before-make timing to prevent signal shorting during state transitions.
It operates across −40°C to +125°C (Y grade), supports continuous channel current up to 100 mA at ±15 V, and achieves −70 dB off isolation and 200 MHz −3 dB bandwidth under ±15 V dual supply-enabling high-fidelity audio, video, and sensor signal routing without distortion or crosstalk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance (RON) | 4.7 Ω max at ±15 V, 25°C - ensures minimal signal attenuation and gain error in precision measurement paths. |
| On-Resistance Flatness | 0.72 Ω max at ±15 V - maintains consistent channel matching across analog voltage range, critical for multiplexer linearity. |
| Supply Range | ±15 V / +12 V / ±5 V - supports legacy industrial rails and modern low-voltage systems without level-shifting. |
| Logic Compatibility | 3 V–compatible inputs - interfaces directly with FPGA, MCU, and DSP I/O without external translators. |
| Break-Before-Make Delay | 30 ns min at ±15 V - prevents momentary short-circuit between source terminals during switching. |
| Off Isolation | −70 dB typ at 1 MHz - suppresses signal coupling between inactive channels in multi-channel routing. |
| −3 dB Bandwidth | 200 MHz typ at ±15 V - preserves integrity of fast-switching signals including video and wideband sensor outputs. |
Pinout & Package
ADG1434YRUZ is available in 20-lead TSSOP (RU-20) package with exposed pad tied to VSS. Pinout is validated per Analog Devices Rev. E datasheet Figures 6 and 9, and Table 8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-high logic selects SxA/SxB path per channel; no internal pull-up/down - requires external biasing. |
| S1A–S4A, S1B–S4B | Analog source terminals | Bi-directional SPDT switch inputs; support rail-to-rail analog signals from VSS to VDD. |
| D1–D4 | Analog drain terminals | Common output nodes per channel; each connects to one SxA or SxB based on INx state. |
| VDD, VSS, GND | Power and reference rails | VDD = most positive supply (up to +16.5 V), VSS = most negative (down to −16.5 V), GND = 0 V reference. |
| EN | Global enable (active-low) | When high, forces all switches OFF; when low, enables INx-controlled switching - used for power gating or system reset. |
| NIC (Pin 15, TSSOP) | No internal connection | Unbonded pad; must be left floating or grounded per layout best practice - no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| iCMOS® high-voltage process | Enables 33 V absolute max rating and ±15 V operation in 4 mm × 4 mm LFCSP - reduces board space vs. legacy high-voltage switches. |
| Rail-to-rail analog signal range | Supports full VSS to VDD swing - eliminates clipping in sensor front-ends and DAC/ADC interface circuits. |
| Ultralow charge injection (−50 pC typ) | Minimizes glitch-induced settling errors in high-impedance sampling circuits like precision data acquisition. |
| 0.5 Ω on-resistance flatness | Ensures <0.01% gain variation over signal range - critical for calibrated gain-switching and programmable attenuator designs. |
| −70 dB crosstalk at 1 MHz | Prevents interference between adjacent channels in multi-signal routing applications such as avionics I/O modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1434YCPZ-REEL7 | LFCSP package (4 mm × 4 mm), same electrical specs, −40°C to +125°C rating, but no EN pin in LFCSP variant per datasheet Table 10. | Preferred for space-constrained PCBs; unsuitable where global enable/disable is required. | Select ADG1434YRUZ when TSSOP form factor and EN functionality are mandatory for system-level power sequencing. |
| MAX4618ESE+ | Quad SPDT, 4.5 Ω RON max, but only rated to +85°C (not +125°C); no iCMOS® process - higher leakage (>10 nA off) and lower supply tolerance (±12 V max). | Acceptable for commercial-grade ATE or lab equipment; not suitable for extended-temperature industrial or avionics use. | Choose ADG1434YRUZ for Y-grade reliability, −40°C to +125°C operation, and <0.3 nA off-leakage in safety-critical systems. |
Compared with ADG1434YCPZ-REEL7, ADG1434YRUZ offers EN control in TSSOP for system-level power management; compared with MAX4618ESE+, it delivers extended temperature range, lower leakage, and higher supply robustness - making it the sole choice for certified industrial and medical platforms.

FAQ
What is the maximum continuous current per channel for ADG1434YRUZ at ±15 V?
The ADG1434YRUZ supports up to 100 mA continuous current per channel at ±15 V supply (VDD = +13.5 V, VSS = −13.5 V), as specified in Table 1 of the Rev. E datasheet. This rating applies across the full −40°C to +125°C operating range, with derating to 40 mA at maximum temperature.
Does ADG1434YRUZ include an enable (EN) pin, and how is it implemented in the TSSOP package?
Yes, ADG1434YRUZ includes an active-low EN pin (Pin 18 in TSSOP), which globally disables all four SPDT switches when driven high. When EN is low, individual channel states are controlled by IN1–IN4. This function is confirmed in Figure 6 and Table 8 of the Rev. E datasheet for the RU-20 package.
What is the on-resistance flatness specification for ADG1434YRUZ, and why does it matter in precision applications?
ADG1434YRUZ specifies 0.72 Ω maximum on-resistance flatness (RFLAT(ON)) at ±15 V, defined as the difference between max and min RON over the full analog signal range. This tight flatness ensures consistent gain and minimal harmonic distortion in programmable gain amplifiers and multiplexed sensor interfaces where signal amplitude varies widely.
Can ADG1434YRUZ operate from a single +12 V supply, and what are the key performance trade-offs?
Yes, ADG1434YRUZ is fully specified for +12 V single-supply operation (Table 2). Key trade-offs include higher max RON (11.2 Ω vs. 6.7 Ω at ±15 V), reduced −3 dB bandwidth (135 MHz vs. 200 MHz), and increased transition time (350 ns max vs. 230 ns). However, it retains 3 V logic compatibility and break-before-make timing.
Is ADG1434YRUZ pin-compatible with ADG1433YRUZ, and what are the practical implications?
No, ADG1434YRUZ (quad SPDT, 20-pin TSSOP) is not pin-compatible with ADG1433YRUZ (triple SPDT, 16-pin TSSOP). Their pin counts, layouts, and EN pin placement differ fundamentally (ADG1433 EN is Pin 14; ADG1434 EN is Pin 18). PCB redesign is required for substitution - they share architecture and specs but not footprint.
