Product details
Overview
DG506ADJ 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, <1µs transition time, and TTL/CMOS-compatible logic inputs. It routes analog signals in data acquisition systems requiring high channel count and rail-to-rail signal handling.
For engineers reviewing the DG506ADJ datasheet, DG506ADJ pinout, DG506ADJ application, or DG506ADJ equivalent, this page delivers verified specifications, package mapping, real-world use cases, and validated alternative options for industrial control, aircraft HUDs, and portable instrumentation design.
Technical Context
The DG506ADJ implements a single-pole, 16-throw analog switch matrix controlled by four binary address lines (A0–A3) and an active-high enable input. Its CMOS architecture ensures symmetrical, bidirectional signal flow with no polarity dependence across the full ±15V analog range.
Break-before-make timing prevents momentary shorting between channels during switching, with a guaranteed 200ns minimum open interval. Latch-up immunity is ensured under powered-down conditions when input signals remain present within absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports rail-to-rail analog signals without clipping in ±15V systems |
| On-Resistance (RDS(ON)) | 270Ω typ - low distortion and minimal gain error in precision signal routing |
| Transition Time | 0.6µs typ - enables sampling rates up to ~1.2MHz in multiplexed ADC front-ends |
| Off-Isolation | 68dB at 500kHz - suppresses crosstalk between inactive channels in multi-sensor systems |
| Supply Voltage Range | ±4.5V to ±18V - operates across industrial, aerospace, and test equipment power rails |
| Channel Leakage (ID(ON)) | ±10nA max at +25°C - preserves accuracy in high-impedance sensor interfaces |
| Enable Turn-On Time | 1µs typ - synchronizes cleanly with microcontroller GPIO or FPGA control logic |
Pinout & Package
DG506ADJ is supplied in a 28-pin wide SOIC (W28-5) package, RoHS-compliant and lead-free compatible. Pin numbering follows standard SOIC conventions with pin 1 marked by notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 | Analog Inputs S1–S16 (S1–S14, S15, S16) | 16 independent analog switch terminals; bidirectional, symmetrical conduction path |
| 15 | D (Drain/Output) | Common analog output node; connects to selected Sx channel when enabled |
| 16 | GND | Digital ground reference for logic inputs and internal biasing |
| 17 | EN (Enable) | Active-high digital control; disables all switches when low (high-impedance state) |
| 18, 19, 20, 21 | A0, A1, A2, A3 | 4-bit binary address bus selecting one of 16 channels (0000 = S1, 1111 = S16) |
| 22 | V− | Negative supply rail; required for bipolar analog signal support |
| 23 | V+ | Positive supply rail; must be ≥ |V−| for proper CMOS switch biasing |
| 24–28 | NC (No Connect) | Internally unconnected; must remain floating or tied to GND per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 200ns minimum open interval prevents channel-to-channel shorting during address changes |
| Latch-up proof construction | Immune to latch-up even when power supplies are off but analog inputs remain active within ratings |
| Symmetrical bidirectional operation | Identical on-resistance and leakage performance regardless of signal direction (S→D or D→S) |
| TTL/CMOS logic compatibility | Accepts 0.8V/2.4V logic thresholds directly from microcontrollers without level-shifting circuitry |
| Low-power CMOS design | Typical supply current of 0.13mA (+) / −0.15mA (−) reduces thermal load in battery-powered systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Harris HI506 | Same pinout, identical truth table, but higher RDS(ON) (350Ω typ) and slower ttransition (1.5µs) | Lower bandwidth and higher insertion loss limit use in >500kHz signal paths | Select HI506 only if legacy board reuse is mandatory and performance margin permits |
| Intersil IH6116 | Drop-in replacement per Maxim's documentation; same electrical specs but wider temp range (−55°C to +125°C for IH6116A) | Better suited for extended-temperature environments like engine control units or downhole tools | Choose IH6116 for new designs targeting harsh environments where DG506ADJ's 0°C to +70°C rating is insufficient |
Compared with HI506 and IH6116, DG506ADJ offers superior switching speed and lower on-resistance in commercial-temperature applications, while IH6116 extends operational range for extreme environments and HI506 serves as a cost-optimized legacy option with relaxed dynamic performance.

FAQ
What is the operating temperature range for DG506ADJ?
The DG506ADJ is specified for 0°C to +70°C operation, matching the "C" suffix grade in Maxim's ordering table. This commercial temperature range suits indoor instrumentation, lab equipment, and portable devices not exposed to extreme ambient conditions. The DG506ADJ does not support extended or military temperature grades-those require variants like DG506AMWI/PR (−55°C to +125°C).
Does DG506ADJ support single-supply operation?
No, DG506ADJ requires dual supplies (V+ and V−) to operate across its full ±15V analog signal range. It cannot function with a single-ended supply such as 0V and +15V. The device relies on symmetric rail voltages to bias internal CMOS transmission gates; attempting single-supply use results in undefined switching behavior and potential damage if input signals exceed V− or V+.
How does DG506ADJ handle break-before-make timing?
DG506ADJ guarantees a minimum 200ns break interval between channel disconnect and reconnect during address transitions, preventing momentary shorts. This is implemented via internal timing control-not external RC networks-and remains consistent across temperature and supply voltage. The DG506ADJ datasheet confirms tOPEN = 0.2µs typ under all rated conditions.
Is DG506ADJ pin-compatible with DG506ACJ or DG506ACK?
Yes-DG506ADJ (28-pin wide SO), DG506ACJ (28-pin plastic DIP), and DG506ACK (28-pin CERDIP) share identical pin functions and numbering. Only package dimensions and thermal characteristics differ. Layout adaptation is required for footprint change, but no schematic or firmware modification is needed when substituting DG506ADJ into designs originally using DG506ACJ or DG506ACK.
What is the maximum analog signal frequency supported by DG506ADJ?
DG506ADJ maintains usable performance up to approximately 500kHz, based on its 68dB off-isolation specification measured at that frequency and 1µs transition time limiting settling behavior. For higher-frequency applications (e.g., RF or video), dedicated high-speed switches or RF multiplexers are recommended-DG506ADJ is optimized for DC through audio-band and low-MHz data acquisition, not broadband signal routing.
