Product details
Overview
DG506ADN+ from Maxim Integrated is a monolithic CMOS 16-channel analog multiplexer (1-of-16) with break-before-make switching, ±4.5V to ±18V dual-supply operation, 270Ω typical on-resistance at ±15V, and TTL/CMOS-compatible digital inputs. It routes analog signals in precision data acquisition systems where channel isolation and rail-to-rail signal handling are critical.
For engineers reviewing the DG506ADN+ datasheet, DG506ADN+ pinout, DG506ADN+ application, or DG506ADN+ equivalent, key selection criteria include its guaranteed latch-up immunity with powered-off supplies, 68dB off-isolation at 500kHz, sub-1µs switching transition time, and compatibility with legacy IH6116/DG506A/HI506 designs.
Technical Context
The DG506ADN+ implements a fully symmetrical, bidirectional analog switch matrix controlled by four address bits (A0–A3) and an active-high enable input (EN). Its CMOS architecture ensures matched on-resistance across all 16 channels and supports analog signal ranges spanning the full supply rails (±15V).
Break-before-make timing guarantees no momentary shorting between channels during address transitions, while internal latch-up protection allows safe operation when input signals remain present during power-down-provided absolute maximum ratings are observed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports rail-to-rail analog inputs/outputs with ±15V supplies. |
| On-Resistance (RDS(ON)) | 270Ω typ - Low distortion and minimal voltage drop for precision signal routing. |
| Off-Isolation (OIRR) | 68dB at 500kHz - High channel-to-channel rejection for multi-channel DAQ integrity. |
| Switching Transition Time | 0.6µs typ - Enables fast multiplexing in high-throughput sampling systems. |
| Supply Voltage Range | ±4.5V to ±18V - Flexible dual-supply support for industrial and aerospace signal chains. |
| Channel Leakage (ID(ON)) | ±10nA max at +25°C - Preserves accuracy in high-impedance sensor interfaces. |

Pinout & Package
DG506ADN+ is supplied in a 28-pin wide SOIC (W28-5) package with exposed pad thermal enhancement. Pin 1 is located at the top-left corner adjacent to the index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input - Connects to +4.5V to +18V rail; powers internal logic and switch drivers. |
| 2–3 | N.C. | No internal connection - Must remain unconnected; no pull-up/down required. |
| 4–11 | S16 to S9 | Analog I/O channels - Bidirectional, low-leakage paths for 16-input/1-output multiplexing. |
| 12 | GND | Signal reference ground - Common return for digital control and analog signal paths. |
| 13–14 | N.C. | No internal connection - Electrically isolated; leave floating. |
| 15 | A2 | Address bit 2 - Part of 4-bit binary select code (A3–A0) determining active channel. |
| 16 | A1 | Address bit 1 - Enables deterministic channel selection without ambiguity or glitching. |
| 17 | A0 | Address bit 0 - LSB of channel address; transitions synchronized to EN edge. |
| 18 | EN | Active-high enable - Disables all switches when low; eliminates crosstalk during reconfiguration. |
| 19–26 | S1 to S8 | Analog I/O channels - Complement pins 4–11 to complete full 16-channel set. |
| 27 | V− | Negative supply input - Connects to −4.5V to −18V rail; defines lower analog rail. |
| 28 | D | Common analog terminal - Single bidirectional port shared across all 16 switched channels. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guarantees 0.2µs minimum open interval between channel disconnect and reconnect - prevents signal shorting during address changes. |
| Latch-up proof construction | Operates safely with input signals present during power-off - eliminates need for external protection diodes or sequencing circuits. |
| TTL/CMOS-compatible logic inputs | Accepts 0.8V/2.4V thresholds - interfaces directly with microcontrollers, FPGAs, and logic families without level-shifting. |
| Symmetrical bidirectional operation | Identical on-resistance and leakage in either direction - enables flexible signal routing as input or output per channel. |
| Drop-in replacement for legacy parts | Pins, timing, and electrical specs match IH6116, HI506, and original DG506A - no PCB or firmware changes required. |
Applications
| Industrial Data Acquisition | Aerospace Sensor Multiplexing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HI506CD | Higher on-resistance (400Ω typ), wider temp range (−55°C to +125°C), same pinout and logic interface. | Better suited for extended-temperature military/aerospace use but consumes more power and exhibits higher THD. | Select HI506CD only if operating beyond +85°C is required and higher on-resistance is acceptable. |
| DG506ACWI | Same die and specs, but non-RoHS plastic SOIC (no '+' suffix); identical timing, leakage, and supply behavior. | Used in cost-sensitive industrial controls where RoHS compliance is not mandated by end-market regulation. | Choose DG506ACWI only for legacy BOM continuity where lead-free assembly is not required. |
Compared with HI506CD and DG506ACWI, DG506ADN+ delivers lower on-resistance and reduced power consumption in a RoHS-compliant wide SOIC package-making it optimal for new designs prioritizing precision, efficiency, and regulatory compliance.

FAQ
What is the maximum supply voltage rating for DG506ADN+?
The DG506ADN+ supports dual-supply operation from ±4.5V to ±18V. Absolute maximum ratings specify V+ up to +44V and V− down to −44V relative to GND, but functional operation is guaranteed only within the ±4.5V to ±18V range. Exceeding ±18V may degrade performance or reliability, even if within absolute limits.
Does DG506ADN+ support bidirectional analog signal flow?
Yes, DG506ADN+ provides fully symmetrical, bidirectional analog switching. Each of its 16 channels (S1–S16) and the common terminal (D) can serve as either input or output, with identical on-resistance, leakage, and capacitance characteristics in both directions-enabling flexible signal routing in complex analog architectures.
Is DG506ADN+ pin-compatible with the original Intersil IH6116?
Yes, DG506ADN+ is a documented drop-in replacement for Intersil's IH6116. Pin assignments, logic thresholds, timing parameters, and electrical specifications are functionally identical, allowing direct substitution without PCB or firmware modifications in existing designs.
What does the '+' suffix in DG506ADN+ indicate?
The '+' suffix in DG506ADN+ denotes a lead(Pb)-free and RoHS-compliant version in the 28-pin wide SOIC (W28-5) package. It has identical electrical performance and pinout to the non-RoHS DG506ACWI variant, differing only in termination plating and environmental compliance certification.
How does DG506ADN+ prevent latch-up during power-down?
DG506ADN+ uses latch-up proof CMOS construction that guarantees immunity to destructive latch-up even when analog input signals remain present while V+ and V− supplies are turned off-provided absolute maximum voltage and current ratings are not violated. This eliminates need for external protection circuitry in hot-swap or power-gated systems.
