Product details
Overview
DG406AK from Maxim Integrated is a 16-channel single-ended CMOS analog multiplexer/demultiplexer designed for precision signal routing in high-reliability systems. It features guaranteed on-resistance matching ≤8 Ω, flatness ≤9 Ω, low charge injection ≤15 pC, and operates across ±4.5V to ±20V dual supplies or +5V to +30V single supply. It is used in aerospace-grade data-acquisition and guidance control systems requiring operation from –55°C to +125°C.
For engineers reviewing the DG406AK datasheet, DG406AK pinout, DG406AK application, or DG406AK equivalent, key selection criteria include guaranteed channel-to-channel RON matching, rail-to-rail analog signal handling (±10V typical), TTL/CMOS-compatible digital control, ESD robustness (>2000V), and CERDIP packaging for extended temperature resilience.
Technical Context
The DG406AK implements a CMOS transmission-gate architecture with bidirectional analog conduction and break-before-make switching logic. Its decoder-driven address inputs (A0–A3) select one of 16 Sx channels to connect to the common D terminal under EN control.
All channels exhibit matched on-resistance over the full analog signal range (±10V), with guaranteed flatness and leakage performance validated at –55°C and +125°C. Input logic thresholds are TTL/CMOS compatible (VAL ≤ 0.8V, VAH ≥ 2.4V), and internal clamping diodes protect against overvoltage on analog and digital pins.

Pinout & Package
Package: 28-pin CERDIP (Ceramic Dual In-line Package), hermetically sealed, lead-free/RoHS-compliant (DG406AK+ designation), suitable for high-reliability and extended-temperature applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply rail - accepts +5V to +30V (single) or up to +20V (dual); substrate internally tied to V+. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG406BRZ | 16-channel, 28-lead SOIC; RON = 90 Ω typ, matching = 12 Ω max; temp range = –40°C to +85°C. | Lacks extended temperature qualification and CERDIP ruggedization; lower ESD rating (1500V). | Preferred for commercial industrial systems where cost and SOIC footprint are prioritized over military-grade reliability. |
| MAX4617CSE+ | 8-channel, 16-lead SOIC; RON = 60 Ω typ, matching = 5 Ω max; temp range = 0°C to +70°C. | Half the channel count; not pin-compatible; lacks dual-supply support and rail-to-rail swing. | Suitable only for space-constrained, lower-channel-count designs with relaxed temperature and supply requirements. |
Compared with ADG406BRZ and MAX4617CSE+, the DG406AK delivers unique value in extended-temperature, high-precision, and high-reliability analog routing - its CERDIP package, –55°C to +125°C rating, and guaranteed 8 Ω matching make it irreplaceable in avionics and downhole applications where alternatives require system-level redesign.

FAQ
What is the maximum allowable supply voltage for DG406AK?
The DG406AK supports dual supplies from ±4.5V to ±20V, or a single supply from +5V to +30V. Absolute maximum ratings specify V+ up to +44V referenced to V−, but operation beyond ±20V or +30V risks exceeding safe power dissipation and degrading RON flatness. For reliable long-term use, stay within the specified operating ranges documented in the DG406AK datasheet.
Does DG406AK support rail-to-rail analog signal switching?
Yes, the DG406AK supports rail-to-rail analog signal handling - signals can swing from V− to V+ without clipping or increased distortion. This capability is confirmed across its full operating temperature range (–55°C to +125°C) and is essential for preserving dynamic range in precision instrumentation using the DG406AK.
Is DG406AK pin-compatible with the original DG406?
Yes, the DG406AK is explicitly designed as a pin-compatible plug-in upgrade for the industry-standard DG406. It shares identical pinout, package dimensions (28-pin CERDIP), and logic interface - enabling direct replacement without PCB modification or firmware changes while delivering improved RON matching, lower charge injection, and extended temperature qualification.
What is the guaranteed charge injection specification for DG406AK?
The DG406AK guarantees charge injection of ≤15 pC maximum across its operating temperature range. This parameter is critical for minimizing voltage glitches in sample-and-hold circuits and integrating amplifiers; the DG406AK's low charge injection directly improves settling time and DC accuracy in precision analog signal chains.
How does the DG406AK handle power supply sequencing?
The DG406AK requires proper supply sequencing: V+ must be applied first, then V−, followed by logic inputs and analog signals. Violating this sequence risks latch-up or excessive leakage. If strict sequencing cannot be guaranteed, external series diodes (as shown in Figure 1 of the DG406AK datasheet) provide overvoltage protection without affecting RON or leakage performance.
