Product details
Overview
DG406CJ+ from Maxim Integrated is a 16-channel single-ended CMOS analog multiplexer with guaranteed 100Ω max on-resistance, 8Ω max channel-to-channel on-resistance matching, and 15pC max charge injection. It operates from +5V to +30V single supply or ±4.5V to ±20V dual supplies and is used in precision data-acquisition systems requiring low signal distortion and rail-to-rail analog handling.
For engineers reviewing the DG406CJ+ datasheet, DG406CJ+ pinout, DG406CJ+ application, or DG406CJ+ equivalent, key selection criteria include on-resistance flatness (9Ω max), input leakage (<5nA at +85°C), ESD robustness (>2000V), TTL/CMOS-compatible digital control, and compatibility with sample-and-hold and test equipment signal routing architectures.
Technical Context
The DG406CJ+ implements a CMOS transmission-gate architecture with bidirectional analog signal paths and integrated address decoding (A0–A3) plus enable (EN) logic. Its rail-to-rail signal handling supports full V− to V+ analog ranges under both single- and dual-supply operation.
Guaranteed parameters include 8Ω max on-resistance matching between any two channels and 9Ω max on-resistance flatness across the full ±10V analog signal range - critical for minimizing gain error in multi-channel measurement systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 100Ω max - ensures minimal voltage drop and gain error in precision analog signal paths |
| On-Resistance Matching | 8Ω max - guarantees consistent channel gain across all 16 inputs for calibrated multichannel systems |
| On-Resistance Flatness | 9Ω max - maintains stable RON over full ±10V signal swing, reducing harmonic distortion |
| Charge Injection | 15pC max - limits sampling error in high-impedance sample-and-hold circuits |
| Input Leakage Current | 5nA max at +85°C - preserves accuracy in high-source-impedance sensor interfaces |
| Analog Signal Range | ±10V (dual supply) or 0V to +10V (single supply) - supports industrial-grade signal levels |
| ESD Protection | >2000V per MIL-STD-883 Method 3015.7 - enables robust handling in manufacturing and field environments |
Pinout & Package
DG406CJ+ is housed in a 28-pin plastic DIP package (0°C to +70°C operating range) with 0.6-inch width and through-hole mounting. Pin 1 is V+, pin 28 is D (bidirectional common output), and pins 19–26 and 4–11 serve as S1–S16 analog inputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply voltage input | Accepts +5V to +30V single supply or +4.5V to +20V positive rail of dual supply |
| V− | Negative supply voltage input | Accepts 0V (GND) for single supply or −4.5V to −20V for dual supply |
| GND | Ground reference | System ground connection; required for single-supply operation and logic interface stability |
| D | Bidirectional common terminal | Single output path for 16:1 multiplexing; handles signals in either direction with matched RON |
| S1–S16 | 16 analog input/output terminals | Individually selectable bidirectional channels; support rail-to-rail analog voltages |
| A0–A3 | 4-bit binary address inputs | Select one of 16 channels; TTL/CMOS-compatible logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) |
| EN | Enable input | Active-low enable; disables all switches when high, preventing signal coupling during address transitions |
| N.C. | No internal connection | Pins 2, 3, and 13 are unconnected; must be left floating or tied to GND for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Pin-compatible upgrade | Direct replacement for legacy DG406 with identical pinout and footprint - no PCB redesign required |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ under all supply configurations, enabling full dynamic range utilization |
| Low charge injection (15pC max) | Minimizes voltage step errors in sample-and-hold circuits with >1MΩ hold capacitors |
| Guaranteed on-resistance flatness (9Ω max) | Ensures <0.1% gain variation across full input voltage range - critical for 12-bit+ data acquisition |
| TTL/CMOS-compatible control | Operates with standard logic families without level-shifting, simplifying interface to microcontrollers and FPGAs |

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 mux with 75Ω max RON, but only specified for ±15V dual supply; no guaranteed matching or flatness specs | Lower on-resistance suits low-voltage systems, but lacks guaranteed matching needed for calibrated multichannel DAQ | Select ADG406BRZ only when absolute RON is prioritized over channel uniformity and temperature-stable flatness |
| MAX4617CSE+ | 8-channel mux with 60Ω max RON, 3.3V/5V single-supply only; no dual-supply capability or leakage specs above +70°C | Designed for compact digital systems; unsuitable for industrial +85°C environments or bipolar signal ranges | Choose MAX4617CSE+ for space-constrained 3.3V embedded designs where rail-to-rail analog range is not required |
Compared with DG406CJ+, ADG406BRZ offers lower on-resistance but sacrifices guaranteed matching and flatness - making it less suitable for precision measurement. MAX4617CSE+ provides smaller size and lower voltage operation but cannot replace DG406CJ+ in dual-supply, high-temperature, or multichannel-calibration applications.

FAQ
What supply voltage ranges does the DG406CJ+ support?
The DG406CJ+ operates from +5V to +30V on a single supply (with V− tied to GND) or ±4.5V to ±20V on dual supplies. It maintains guaranteed performance across this full range, including on-resistance flatness and leakage specifications - verified per the datasheet's Electrical Characteristics tables for both single- and dual-supply conditions. DG406CJ+ supports unbalanced supplies like +24V/−5V as long as the total differential remains within +44V.
Is the DG406CJ+ pin-compatible with older DG406 variants?
Yes, the DG406CJ+ is explicitly documented as a pin-compatible plug-in upgrade for industry-standard DG406 devices. Its 28-pin DIP footprint, pin assignments (including V+, V−, GND, D, S1–S16, A0–A3, EN), and electrical interface match legacy DG406 parts - enabling direct replacement without PCB modification. This compatibility is confirmed in the "Pin Configurations" and "Features" sections of the official datasheet.
What is the maximum allowable analog signal range for DG406CJ+ at ±15V supplies?
At ±15V dual supplies, the DG406CJ+ supports an analog signal range of ±10V - meaning input/output signals can swing from −10V to +10V referenced to GND. This is specified in the Electrical Characteristics table under "Analog Signal Range" and confirmed by the Typical Operating Characteristics graphs (TOC-01 and TOC-02). Exceeding ±10V risks increased on-resistance variation and potential damage if absolute maximum ratings are breached.
How does the DG406CJ+ handle charge injection in sample-and-hold applications?
The DG406CJ+ guarantees ≤15pC maximum charge injection, measured under defined conditions (VD = ±10V, VS = ±10V, Figure 5). In sample-and-hold circuits, this low value minimizes voltage step errors on hold capacitors - especially critical for high-resolution systems using >100pF capacitors. The datasheet confirms this spec is guaranteed by design and tested at hot temperature, ensuring reliability across the full 0°C to +70°C operating range of DG406CJ+.
Does the DG406CJ+ require external protection diodes for overvoltage conditions?
No, external protection diodes are optional. The DG406CJ+ includes internal clamping diodes on all analog and digital pins (per Note 1 in Absolute Maximum Ratings), limiting signals exceeding V+ or V−. However, if strict overvoltage immunity beyond ±2V is required - such as in environments with frequent probe mishandling - external series diodes (as shown in Figure 1) can be added. Doing so reduces the usable analog range by ~1V but preserves DG406CJ+'s low-leakage and low-RON performance.
