Product details
Overview
DG407DN from Maxim Integrated is a dual 8-channel CMOS analog multiplexer/demultiplexer designed for bidirectional signal routing in precision analog systems. It features guaranteed on-resistance matching ≤8Ω, flatness ≤9Ω, low charge injection ≤15pC, and operates from ±4.5V to ±20V dual supplies or +5V to +30V single supply. It is used in data-acquisition systems requiring channel-to-channel signal integrity and rail-to-rail analog handling.
For engineers reviewing the DG407DN datasheet, DG407DN pinout, DG407DN application, or DG407DN equivalent, key selection criteria include guaranteed on-resistance matching across channels, low leakage (<5nA at +85°C), ESD robustness (>2000V), TTL/CMOS-compatible digital control, and PLCC-28 packaging for high-density mixed-signal PCB layouts.
Technical Context
The DG407DN implements a dual independent 8:1 analog switch architecture with separate address decoding (A0–A2) and enable (EN) per section, supporting simultaneous or isolated channel selection. Each section routes one of eight bidirectional analog inputs (S1A–S8A or S1B–S8B) to its respective output (DA or DB), with rail-to-rail signal swing and symmetrical on-resistance behavior.
It uses enhanced CMOS process technology to guarantee parameter matching and flatness over temperature and signal range - critical for sample-and-hold and test equipment where gain/offset errors must be minimized. Digital inputs are TTL/CMOS compatible, and internal protection diodes clamp analog signals exceeding V+ or V−, provided current is limited to 30mA.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG407BRZ | Single-supply only (+3V to +30V); no dual-supply support; on-resistance 60Ω (typ), but no guaranteed matching spec | Suitable for cost-sensitive, single-rail systems; not recommended for precision bipolar signal routing | Select if operating exclusively from +12V or +24V and channel matching is not required |
| MAX4617CSE+ | Dual SPST (not multiplexer); 4Ω on-resistance; no address decoding; requires external logic for 8:1 function | Used in discrete switch banks where flexibility > integration; lacks built-in decoder | Select only when discrete control of each path is preferred and board space allows added logic |
Compared with ADG407BRZ and MAX4617CSE+, the DG407DN uniquely delivers guaranteed channel matching, dual-supply operation, integrated 3-bit decoding, and PLCC packaging - making it the only option qualified for high-accuracy, temperature-stable, dual-rail multiplexing in industrial and aerospace designs.

FAQ
What is the operating temperature range for the DG407DN?
The DG407DN is rated for operation from -40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet. The device maintains guaranteed specifications - including on-resistance matching and leakage - across this full range, making DG407DN suitable for harsh-environment deployments such as avionics and factory automation.
Is the DG407DN pin-compatible with older DG407 variants?
Yes, the DG407DN is explicitly described as a "pin-compatible plug-in upgrade" for industry-standard DG407 devices. Its PLCC-28 footprint matches DG407DN+ variants, and all pin functions - including DA, DB, S1A–S8A, S1B–S8B, A0–A2, EN, V+, V−, and GND - align exactly with legacy DG407 pinouts. No PCB redesign is needed when upgrading to DG407DN.
Does the DG407DN support single-supply operation?
Yes, the DG407DN supports single-supply operation from +5V to +30V. In this mode, V− must be connected to GND. The datasheet confirms rail-to-rail analog signal handling from 0V to V+, with specified performance (e.g., on-resistance, leakage) validated at +12V and +15V single-supply conditions. This enables use in battery-powered instrumentation and industrial PLC I/O modules.
What is the maximum analog signal voltage the DG407DN can handle?
The DG407DN supports analog signals from V− to V+, with absolute maximum ratings allowing V+ up to +44V referenced to V−. Under standard dual-supply operation (±15V), the usable analog range is ±10V - verified in Electrical Characteristics tables. At ±20V supplies, the range extends to ±15V. Exceeding these ranges risks exceeding the ±2V diode clamp limit and damaging the device.
How does the DG407DN achieve guaranteed on-resistance matching?
The DG407DN achieves guaranteed ≤8Ω on-resistance matching between channels through process-controlled layout symmetry and laser-trimmed design techniques documented in Maxim's characterization reports. This specification is 100% tested at temperature extremes and guaranteed across the full -40°C to +85°C range - unlike typical muxes where matching degrades significantly with temperature or signal voltage.
