Product details
Overview
DG408DJ+ from Maxim Integrated is a precision 1-of-8 CMOS analog multiplexer/demultiplexer designed for bidirectional signal routing in high-fidelity data-acquisition and test systems. It features guaranteed 100Ω max on-resistance, 8Ω max channel-to-channel matching, 15pC max charge injection, rail-to-rail analog signal handling (±20V dual / +30V single supply), and operates across -40°C to +85°C.
For engineers reviewing the DG408DJ+ datasheet, DG408DJ+ pinout, DG408DJ+ application, or DG408DJ+ equivalent, key selection criteria include on-resistance flatness (9Ω max), low input off-leakage (<5nA at +85°C), TTL/CMOS-compatible digital control, ESD protection (>2000V), and compatibility with ±5V to ±20V dual or +5V to +30V single supplies.
Technical Context
The DG408DJ+ implements an 8-channel analog switch matrix controlled by three address bits (A0–A2) and an active-low enable (EN), with CMOS decoding logic selecting exactly one of eight bidirectional Sx-to-D paths. All switches conduct equally in both directions and maintain consistent rDS(ON) across the full analog signal range (±10V typical).
It supports dual-supply operation (V+ = ±5V to ±20V, V− referenced) or single-supply mode (V− tied to GND, V+ = +5V to +30V), with guaranteed performance over temperature and supply voltage variations-on-resistance increases only modestly at extremes (e.g., 175Ω max at −55°C, ±20V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 100Ω max - ensures minimal signal attenuation and gain error in precision measurement paths |
| On-Resistance Matching | 8Ω max - enables accurate differential or ratiometric measurements across channels |
| Charge Injection | 15pC max - limits voltage glitch and settling time in sample-and-hold circuits |
| Analog Signal Range | ±20V dual / +30V single - supports industrial sensor interfaces and wide-dynamic-range instrumentation |
| Off-Leakage Current | 5nA max at +85°C - preserves accuracy in high-impedance sensor front-ends and integrator applications |
| Enable Turn-On Time | 150ns max - enables fast channel switching in automated test equipment (ATE) |

Pinout & Package
Package: 16-pin plastic DIP (P16-2), through-hole mount, 0.300" wide body, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 16 | A0, A1, A2 | Binary address inputs selecting one of eight analog channels (S1–S8 → D) |
| 2 | EN | Active-low enable - disables all switches when high, reducing leakage and crosstalk |
| 3 | V− | Negative supply rail - required for dual-supply operation; tied to GND for single-supply use |
| 4–7, 9–12 | S1–S4, S5–S8 | Bidirectional analog inputs - support signal routing in either direction with matched impedance |
| 8 | D | Bidirectional analog output/common terminal - connects to selected Sx channel when enabled |
| 13 | V+ | Positive supply rail - sets upper analog voltage limit and powers internal logic |
| 14 | GND | Ground reference - used as logic ground and return path for single-supply configurations |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE UPGRADE | Direct replacement for legacy DG408 - no PCB or firmware changes required |
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor interfacing |
| TTL/CMOS-Compatible Control | Accepts standard logic levels (VAL ≤ 0.8V, VAH ≥ 2.4V) - eliminates level-shifting in mixed-voltage systems |
| Low Power Consumption | 1.25mW max - enables use in thermally constrained or battery-backed instrumentation |
| Guaranteed On-Resistance Flatness | 9Ω max variation across signal range - maintains linearity in precision gain/attenuation stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | 100Ω max rDS(ON), but 25pC charge injection (vs. 15pC); −40°C to +85°C; SOIC-16 package | Higher charge injection may increase settling time in S/H or integrator circuits | Select ADG408BRZ only if SOIC-16 footprint is mandatory and charge injection tolerance allows |
| TS5A23159DGSR | Lower rDS(ON) (0.9Ω typ), but limited supply (2.5V–5.5V); −40°C to +85°C; 10-pin VSSOP | Not suitable for ±15V or high-voltage industrial signal routing | Choose TS5A23159DGSR only for low-voltage, high-speed portable instrumentation where voltage range is constrained |
Compared with ADG408BRZ and TS5A23159DGSR, the DG408DJ+ uniquely balances high-voltage operation (+30V single / ±20V dual), ultra-low charge injection (15pC), and industrial temperature range in a through-hole DIP package-making it optimal for legacy-replacement and ruggedized test/measurement designs.

FAQ
What is the maximum supply voltage rating for DG408DJ+?
The DG408DJ+ supports dual-supply operation up to ±20V (V+ to V− ≤ 44V) and single-supply operation up to +30V (with V− tied to GND). Absolute maximum ratings specify V+ to V− ≤ 44V and V+ to GND ≤ 25V. Exceeding these limits risks permanent damage, per MIL-STD-883 stress guidelines.
Does DG408DJ+ support rail-to-rail analog signal switching?
Yes, DG408DJ+ supports rail-to-rail analog signal handling: signals can swing from V− to V+ without clipping or increased distortion. This is confirmed in the Electrical Characteristics table (VANALOG = ±20V dual / +30V single) and is critical for interfacing with full-scale industrial sensors and op-amp outputs.
Is DG408DJ+ pin-compatible with the original DG408?
Yes, DG408DJ+ is explicitly specified as a pin-compatible plug-in upgrade for the industry-standard DG408. Pin functions, layout, and mechanical dimensions match the 16-pin DIP package (P16-2), enabling drop-in replacement without PCB modification or firmware changes.
What is the guaranteed on-resistance matching specification for DG408DJ+?
DG408DJ+ guarantees ≤8Ω maximum on-resistance matching between any two channels (ΔrDS(ON)), measured across the full operating temperature range (−40°C to +85°C) and specified supply conditions. This parameter is 100% tested and ensures consistent gain scaling in multi-channel instrumentation.
How does DG408DJ+ perform in terms of charge injection, and why does it matter?
DG408DJ+ guarantees ≤15pC maximum charge injection-critical for minimizing voltage glitches in sample-and-hold circuits and integrators. Low charge injection directly reduces aperture error and settling time, enabling higher effective resolution in precision data-acquisition systems using the DG408DJ+.
