Product details
Overview
DG201ADY+ from Maxim Integrated is a quad SPST normally closed analog switch IC designed for high-voltage signal routing in precision instrumentation and industrial control systems. It operates over ±4.5V to ±18V dual supplies, delivers 115Ω typical RDS(ON) at ±15V, guarantees break-before-make switching, and supports -40°C to +85°C operation in 16-pin SO package.
For engineers reviewing the DG201ADY+ datasheet, DG201ADY+ pinout, DG201ADY+ application, or DG201ADY+ equivalent, key selection criteria include guaranteed analog signal range (±15V), low charge injection (20pC), fast turn-off time (450ns max), and absence of VL supply requirement - critical for portable and space-constrained designs.
Technical Context
The DG201ADY+ implements monolithic CMOS architecture with integrated level-shifting logic, enabling TTL/CMOS-compatible control inputs while switching bipolar analog signals up to ±15V. Its nonlatching behavior under power-loss conditions ensures robustness when input signals remain active during supply interruption.
Each of the four independent SPST switches features matched RDS(ON) tracking across channels and temperature, with <1.0nA typical OFF-leakage at ±14V. The device eliminates the third VL supply required by legacy equivalents, simplifying system-level power architecture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail bipolar signal switching without clipping |
| RDS(ON) (max) | 175Ω at ±10V - ensures minimal insertion loss and gain error in precision signal paths |
| Turn-Off Time (tOFF) | 450ns max - enables high-speed multiplexing in test equipment and data acquisition |
| Charge Injection | 20pC - limits voltage glitch on sampled-hold nodes and ADC front-ends |
| OFF-Isolation | 70dB at 100kHz - suppresses crosstalk between adjacent switched channels |
| Supply Range | ±4.5V to ±18V - accommodates wide-range industrial and military power rails |
| Operating Temp | -40°C to +85°C - qualified for extended-temperature industrial environments |
Pinout & Package
Package: 16-pin SO (Small Outline) per JEDEC MS-012, 1.27mm pitch, body width 3.9mm, thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Active-low logic inputs controlling respective SPST switches (low = ON) |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - connect to analog signal source or load side |
| 3, 6, 11, 14 | S1–S4 | Source terminals - connect to analog signal path or common reference |
| 4 | V− | Negative supply rail - must be connected for proper analog channel biasing |
| 5 | GND | Digital ground reference - separate from analog return in mixed-signal layouts |
| 12 | N.C. | No internal connection - leave unconnected or tie to GND for mechanical stability |
| 13 | V+ | Positive supply rail - also tied to substrate for latch-up immunity |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates dedicated logic supply rail, reducing BOM count and PCB area vs. legacy DG211 |
| Guaranteed break-before-make | Prevents momentary short-circuit between channels during state transitions |
| Nonlatching under power loss | Remains functional and safe when V+/V− are removed while analog signals persist |
| CMOS/TTL logic compatible | Accepts 0.8V/2.4V thresholds - interoperable with microcontrollers and FPGAs without level shifters |
| Low power consumption | 0.1mA max I+ and |I−| - extends battery life in portable instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single SPST, 12V max supply, 60Ω RDS(ON), no negative supply support | Limited to unipolar signal routing; unsuitable for ±15V bipolar systems | Select only for low-voltage, single-channel, cost-sensitive designs where bipolar operation is unnecessary |
| ADG1414BRUZ | Quad SPST, ±15V rated, 1.8Ω RDS(ON), requires VL supply, 16-TSSOP | Lower on-resistance but adds complexity via VL rail; higher leakage at temperature extremes | Prefer when ultra-low RDS(ON) dominates design priority and VL supply is already available |
Compared with MAX4617ESE+ and ADG1414BRUZ, the DG201ADY+ uniquely balances bipolar ±15V capability, no-VL simplicity, and industrial temperature rating - making it optimal for ruggedized, multi-channel analog routing where supply count and reliability are constrained.

FAQ
What is the maximum analog signal voltage range supported by the DG201ADY+?
The DG201ADY+ supports an analog signal range of ±15V when operated with ±15V supplies. This is specified in the Electrical Characteristics table under VANALOG, and applies across the full -40°C to +85°C operating temperature range. Operation outside this range risks exceeding absolute maximum ratings and may cause permanent damage to the DG201ADY+.
Does the DG201ADY+ require a third VL supply voltage like some legacy analog switches?
No, the DG201ADY+ does not require a third VL supply. Unlike the original DG211 and certain competing devices, the DG201ADY+ integrates internal level-shifting circuitry that allows TTL/CMOS-compatible logic inputs to directly control the analog switches using only V+ and V− supplies. This eliminates external VL generation and reduces system complexity for the DG201ADY+.
What is the guaranteed turn-off time specification for the DG201ADY+?
The DG201ADY+ has a maximum guaranteed turn-off time (tOFF) of 450ns under standard test conditions (V+ = +15V, V− = −15V, RL = 1kΩ, CL = 35pF). This value is explicitly listed in the DG201A Electrical Characteristics table and applies across the full operating temperature range, ensuring predictable timing behavior in high-speed multiplexing applications using the DG201ADY+.
How does the DG201ADY+ behave if power supplies are disconnected while analog signals remain present?
The DG201ADY+ is specifically designed to be nonlatching under such fault conditions. Maxim guarantees that the DG201ADY+ will not enter a destructive latch-up state even when V+ and V− are removed while input signals remain connected to S or D pins. This behavior is confirmed in the General Description and Absolute Maximum Ratings sections of the DG201ADY+ datasheet.
What package type is used for the DG201ADY+ and what are its key mechanical dimensions?
The DG201ADY+ uses a 16-pin SO (Small Outline) package per JEDEC MS-012 outline, with 1.27mm lead pitch and 3.9mm body width. Pin 12 is N.C., and the package contains no thermal pad. These mechanical specifications are documented in the Package Information section of the DG201ADY+ datasheet and verified against Maxim's official package drawings.
