Product details
Overview
DG408C/D from Maxim Integrated is a precision 1-of-8 CMOS analog multiplexer/demultiplexer designed for bidirectional signal routing in precision 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 (±10V), and operates from +5V to +30V single or ±5V to ±20V dual supplies.
For engineers reviewing the DG408C/D datasheet, DG408C/D pinout, DG408C/D application, or DG408C/D equivalent, this device is selected for high-accuracy analog switching where low leakage (<5nA at +85°C), flat on-resistance over signal range (9Ω max), and TTL/CMOS-compatible digital control are critical in sample-and-hold, guidance systems, and audio routing.
Technical Context
The DG408C/D implements an 8-channel analog switch matrix with address-decoded selection (A0–A2) and enable-controlled operation (EN). Its CMOS transmission-gate architecture supports true bidirectional conduction with symmetrical on-resistance characteristics across all channels.
It guarantees performance under both single-supply (+5V to +30V) and dual-supply (±5V to ±20V) configurations, with ESD protection exceeding 2000V per MIL-STD-883 Method 3015.7 and specified operation from 0°C to +70°C - consistent with its "C" grade temperature rating and dice form factor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (rDS(ON)) | 100Ω max - ensures minimal signal attenuation and gain error in precision analog paths |
| On-Resistance Matching | 8Ω max - enables accurate channel-to-channel ratio-matching in differential or multi-channel measurement systems |
| On-Resistance Flatness | 9Ω max - maintains consistent gain and linearity across full ±10V analog input range |
| Charge Injection | 15pC max - limits voltage glitch and settling time in sample-and-hold circuits |
| Input Off-Leakage Current | 5nA max at +85°C - preserves accuracy in high-impedance sensor interfaces and integrator applications |
| Analog Signal Range | ±10V - supports full-rail operation with ±15V supplies, enabling direct interfacing with industrial sensors |
| Supply Voltage Range | +5V to +30V (single); ±5V to ±20V (dual) - provides flexibility in legacy and mixed-voltage system designs |
Pinout & Package
DG408C/D is supplied as bare die (dice), with no standardized surface-mount or through-hole package. Pin functionality follows the 16-pin DIP/SO/TSSOP pinout layout, adapted for wafer-level integration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A2 | Binary Address Inputs | Select one of eight analog channels (S1–S8) when EN = logic high |
| EN | Enable Input | Active-high control: disables all switches when low, preventing unintended conduction |
| S1–S8 | Bidirectional Analog Inputs | Eight independent analog signal terminals; interchangeable as inputs or outputs |
| D | Bidirectional Analog Output/Commutator | Common terminal connected to selected Sx channel; supports demux and mux modes |
| V+, V- | Positive/Negative Supply Rails | Power the internal CMOS switch array; define analog signal swing boundaries |
| GND | Ground Reference | Logic ground reference; tied to V- in single-supply operation |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | 100Ω typical on-resistance (120Ω max), 20pC charge injection, -40°C to +85°C grade | Higher leakage (10nA at +85°C) and wider charge injection spec limit use in ultra-low-drift S/H designs | Preferred for extended temperature industrial systems requiring RoHS-compliant TSSOP packaging |
| MAX4617ESE+ | 8-channel, but only 35Ω max on-resistance and 5pC max charge injection; requires +3V to +16V supply | Superior dynamic specs suit high-speed data acquisition, but narrower supply range excludes ±20V legacy systems | Chosen when sub-10pC charge injection and faster switching (<100ns) outweigh supply flexibility needs |
Compared with DG408C/D, ADG408BRUZ offers broader temperature support but looser leakage and charge specs, while MAX4617ESE+ delivers tighter dynamic performance at the cost of supply voltage compatibility - making DG408C/D optimal for cost-sensitive, wide-supply, precision DC-coupled routing.

FAQ
What is the operating temperature range for DG408C/D?
DG408C/D is rated for 0°C to +70°C operation, consistent with its "C" grade designation. This range is validated across all key parameters including on-resistance matching (8Ω max), charge injection (15pC max), and off-leakage current (5nA max at +85°C derated). The dice form factor allows integration into custom thermal environments, but system-level validation remains the designer's responsibility.
Does DG408C/D support single-supply operation?
Yes, DG408C/D supports +5V to +30V single-supply operation. In this configuration, V- must be connected to GND, and the analog signal range extends from 0V to V+. For example, with +12V supply, the usable analog range is 0V to +12V. Performance specifications such as 100Ω max on-resistance and 15pC max charge injection are guaranteed under single-supply conditions per the datasheet's Electrical Characteristics table.
What is the pinout configuration for DG408C/D?
DG408C/D is supplied as bare die (dice), not packaged. Its terminal mapping follows the standard 16-pin layout used in DIP, SO, and TSSOP versions: pins A0–A2 (address), EN (enable), S1–S8 (analog inputs), D (common analog terminal), V+, V-, and GND. No bond pad diagram is published, so integration requires adherence to Maxim's wafer-level interface guidelines and die attach alignment to the functional pin map.
How does DG408C/D differ from the original DG408?
DG408C/D is a redesigned, improved version of the industry-standard DG408. Key enhancements include guaranteed 8Ω max channel matching (vs. unspecified in original), 9Ω max on-resistance flatness, 15pC max charge injection (vs. 25pC), and >2000V ESD protection. It is pin-compatible and functionally identical, making DG408C/D a drop-in upgrade that improves accuracy and reliability without design changes.
Is DG408C/D suitable for audio signal routing?
Yes, DG408C/D is widely used in professional audio routing due to its rail-to-rail ±10V analog signal handling, low 100Ω max on-resistance, and 5nA max off-leakage at +85°C. These traits minimize crosstalk (<−92dB), preserve wide dynamic range, and prevent audible distortion in line-level and instrument-level paths. Its TTL/CMOS-compatible control also simplifies integration with FPGA- or MCU-based mixer logic.
