Product details
Overview
DG201ADJ+ from Maxim Integrated is a quad SPST normally closed analog switch IC designed for high-voltage bipolar signal routing in precision instrumentation and test systems. It operates over ±4.5V to ±18V supplies, delivers 115Ω typical RDS(ON) at ±15V, guarantees break-before-make switching, and supports -40°C to +85°C industrial temperature range in 16-pin plastic DIP package.
For engineers reviewing the DG201ADJ+ datasheet, DG201ADJ+ pinout, DG201ADJ+ application, or DG201ADJ+ equivalent, this page provides verified electrical parameters, validated pin functions, real-world use cases in military radios and guidance systems, and two confirmed alternative parts with documented functional and thermal differences.
Technical Context
The DG201ADJ+ implements four independent CMOS SPST switches with integrated logic-level translation, enabling TTL/CMOS-compatible control across its full ±18V analog signal range. Its monolithic design eliminates the VL supply required by legacy equivalents, simplifying power architecture.
Guaranteed nonlatching behavior persists even when V+ and V− are disconnected while analog signals remain applied to S/D terminals. Switching performance is characterized with tON ≤ 600ns and tOFF ≤ 450ns under 1kΩ/35pF load conditions, supporting high-speed multiplexing in communications and PBX systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports full-rail bipolar signal switching without clipping in ±15V systems. |
| RDS(ON) (max) | 200Ω at ±15V - Ensures low insertion loss and minimal gain error in precision amplifier signal paths. |
| Turn-ON Time (max) | 600ns - Enables reliable sampling of signals up to ~300kHz without timing skew between channels. |
| Turn-OFF Time (max) | 450ns - Guarantees fast channel isolation critical for time-division multiplexing in test equipment. |
| OFF-Isolation | 70dB at 100kHz - Suppresses crosstalk between adjacent switched channels in dense PCB layouts. |
| Supply Range | ±4.5V to ±18V - Allows direct integration into legacy ±12V and ±15V industrial power rails without regulation. |
| Logic Compatibility | CMOS/TTL - Accepts standard 0V/5V control inputs without level-shifting circuitry. |
Pinout & Package
Package: 16-pin plastic DIP (0.300" wide), RoHS-compliant, through-hole mountable with 0.1" lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Active-low logic inputs controlling respective SPST switches; compatible with 0V/5V TTL/CMOS. |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - Analog outputs routed to system load or next stage; bidirectional operation supported. |
| 3, 6, 11, 14 | S1–S4 | Source terminals - Analog inputs connected to signal sources; normally closed path to Dx when INx = LOW. |
| 4 | V− | Negative supply rail input - Must be connected to system −15V (or −4.5V to −18V) for proper switch biasing. |
| 5 | GND | Digital ground reference - Shared return for logic inputs; isolated from analog signal ground per layout best practice. |
| 12 | N.C. | No connection - Internally unconnected; must remain floating, not tied to any net. |
| 13 | V+ | Positive supply rail input - Connected to substrate; requires +15V (or +4.5V to +18V); decoupling mandatory. |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third auxiliary voltage rail, reducing BOM count and PCB space vs. legacy DG211-based designs. |
| Guaranteed break-before-make | Prevents momentary short-circuit between analog channels during switching transitions in multiplexer applications. |
| Nonlatching with supplies off | Allows hot-swap signal routing: analog inputs may remain live while power rails are cycled without device damage. |
| Low 20pC charge injection | Minimizes voltage glitch on sampled-hold nodes, critical for 12-bit+ data acquisition accuracy. |
| ±18V continuous operation | Supports direct interface to op-amp stages operating beyond ±12V rails without external clamping diodes. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CSE+ | Single-supply only (1.8V–12V); no bipolar capability; 4Ω RDS(ON); 30ns switching. | Not suitable for ±15V signal routing; limited to low-voltage portable systems. | Select only if system uses single-ended 3.3V/5V rails and requires ultra-low RDS(ON). |
| ADG1412BRUZ | Bipolar ±15V rated; 1.8Ω RDS(ON); 125ns switching; requires external VL for logic level translation. | Higher drive current capability but adds complexity with VL supply; better for high-speed, low-distortion audio routing. | Choose when lowest possible RDS(ON) and fastest switching outweigh added power rail overhead. |
Compared with MAX4617CSE+ and ADG1412BRUZ, the DG201ADJ+ uniquely balances bipolar ±18V operation, no-VL simplicity, and industrial temperature support-making it optimal for legacy test gear, military comms, and guidance hardware where reliability under voltage stress is non-negotiable.

FAQ
What is the maximum analog signal voltage range supported by the DG201ADJ+?
The DG201ADJ+ supports an analog signal range of ±15V when operated with ±15V supplies. Its absolute maximum ratings allow continuous operation from ±4.5V to ±18V, and the analog signal can swing fully between V− and V+ rails-enabling direct interfacing with op-amps and sensors operating at ±12V or ±15V without attenuation or clamping.
Does the DG201ADJ+ require a separate VL logic supply voltage?
No, the DG201ADJ+ does not require a VL supply. Unlike earlier analog switches such as the DG211, Maxim's DG201ADJ+ integrates internal level translation, allowing direct TTL/CMOS-compatible control (0V/5V logic inputs) while operating from bipolar ±4.5V to ±18V analog supplies-reducing system complexity and component count.
What is the guaranteed switching speed of the DG201ADJ+ at full temperature range?
The DG201ADJ+ guarantees tON ≤ 600ns and tOFF ≤ 450ns across its full −40°C to +85°C operating temperature range, measured under standard conditions (V+ = +15V, V− = −15V, RL = 1kΩ, CL = 35pF). These values are production-tested limits-not typical-only specs-ensuring timing predictability in real-time control loops.
How does the DG201ADJ+ prevent latch-up when power supplies are disconnected?
The DG201ADJ+ incorporates proprietary process and layout techniques that guarantee nonlatching behavior-even when V+ and V− are powered down while analog signals remain present on S/D pins. This eliminates risk of destructive current flow through parasitic SCR structures, a critical feature for hot-swap signal routing in field-replaceable modules using DG201ADJ+.
What is the RDS(ON) value of the DG201ADJ+ at ±12V supplies?
At ±12V supplies, the DG201ADJ+ exhibits RDS(ON) ≈ 165Ω (typical), based on Maxim's published RDS(ON) vs. supply curve. The datasheet specifies 200Ω maximum at ±15V; since RDS(ON) increases as supply voltage decreases, the ±12V value remains well within the 250Ω maximum limit specified for worst-case conditions across temperature and process variation.
