Product details
Overview
DG407CWI+T 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 widely used in data-acquisition systems requiring channel-to-channel signal integrity.
For engineers reviewing the DG407CWI+T datasheet, DG407CWI+T pinout, DG407CWI+T application, or DG407CWI+T equivalent, key selection criteria include guaranteed RDS(ON) matching across channels, rail-to-rail analog signal handling (±10V typical), TTL/CMOS-compatible digital control, and ESD protection >2000V per MIL-STD-883 Method 3015.7.
Technical Context
The DG407CWI+T implements a dual independent 8:1 analog switch architecture with separate address inputs (A0–A2) and enable (EN) per section, supporting simultaneous or isolated channel selection. Each section routes one of eight bidirectional analog signals (S1A–S8A or S1B–S8B) to its respective output (DA or DB).
It uses enhanced CMOS process technology to guarantee parameter matching across channels - including on-resistance (ΔRDS(ON) ≤8Ω), flatness (≤9Ω over ±10V range), and low leakage (<5nA at +85°C). Digital inputs accept TTL/CMOS logic levels, and internal clamping diodes protect against overvoltage on analog and control pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual 8-channel analog multiplexer/demultiplexer with independent A/B sections |
| On-Resistance (max) | 100Ω - ensures minimal signal attenuation and gain error in precision gain-setting or sensor-mux applications |
| On-Resistance Matching (max) | 8Ω - guarantees consistent gain and offset across selected channels in multi-sensor or calibration systems |
| Charge Injection (max) | 15pC - limits voltage glitch on sample-and-hold capacitors, preserving ADC accuracy |
| Analog Signal Range | Rail-to-rail: ±10V with ±15V supplies - supports full dynamic range of industrial sensors and DAC outputs |
| Supply Range | ±4.5V to ±20V dual or +5V to +30V single - enables flexible power architecture in mixed-signal test and control equipment |
| ESD Protection | >2000V HBM per MIL-STD-883 Method 3015.7 - enhances robustness during board handling and system integration |
Pinout & Package
Package: 28-pin Wide SO (SOIC-W), RoHS-compliant, surface-mount, 7.6mm body width, 1.27mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input - must be powered before V− and logic inputs to prevent latch-up |
| 2 | DB | Bidirectional analog output for second 8-channel section (S1B–S8B) |
| 3, 13, 14 | N.C. | No internal connection - must remain unconnected on PCB |
| 4–11 | S8B–S1B | Bidirectional analog inputs for section B - routed to DB when selected |
| 12 | GND | Ground reference - common return for supplies and logic interface |
| 15–17 | A2, A1, A0 | Binary address inputs for section A - determine which of S1A–S8A connects to DA |
| 18 | EN | Enable input for section A - high enables switching; low disconnects all Sx→DA paths |
| 19–26 | S1A–S8A | Bidirectional analog inputs for section A - routed to DA when selected and EN = high |
| 27 | V− | Negative supply input - powers analog core; sequencing after V+ prevents damage |
| 28 | DA | Bidirectional analog output for first 8-channel section (S1A–S8A) |
Key Features

| TTL/CMOS COMPATIBLE CONTROL | Logic thresholds: VAL ≤0.8V, VAH ≥2.4V - interfaces directly with microcontrollers and FPGAs without level shifters |
Applications
| Sample-and-Hold Circuits | Test Equipment Signal Routing |
|---|---|
Use Scenario: Multiplexing multiple sensor outputs into a single high-speed sample-and-hold amplifier prior to ADC conversion. IC Role / Device Role / Timing Role: Dual 8:1 analog switch selecting one of 16 total inputs (8 per section) with break-before-make timing to prevent signal shorting. Use Value: Guaranteed ≤15pC charge injection minimizes hold-mode voltage error; ≤8Ω channel matching ensures consistent settling across channels. |
Use Scenario: Reconfigurable signal path in automated test equipment (ATE) for routing DUT signals to measurement instruments. IC Role / Device Role / Timing Role: Bidirectional analog mux enabling flexible stimulus/response routing between sources, DUT, and meters. Use Value: Rail-to-rail ±10V operation supports wide test signal ranges; >2000V ESD rating improves reliability in lab environments. |
| Guidance and Control Systems | Audio Signal Routing |
Use Scenario: Channel selection for redundant inertial sensor inputs in flight control units requiring deterministic signal integrity. IC Role / Device Role / Timing Role: High-reliability analog switch with guaranteed leakage <5nA at +85°C for long-term bias stability. Use Value: Low off-leakage and matched on-resistance preserve signal fidelity in closed-loop feedback paths. |
Use Scenario: Analog audio channel switching in professional mixing consoles or broadcast gear with minimal crosstalk. IC Role / Device Role / Timing Role: Dual-section mux routing line-level signals (±2V) with <−92dB crosstalk and <−69dB off-isolation. Use Value: 8Ω max channel matching prevents volume imbalance; low capacitance (CD(ON) ≈70pF) preserves high-frequency response. |
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; RDS(ON) = 120Ω (typ), no guaranteed matching spec | Best suited for battery-powered or single-rail systems where bipolar supply is unavailable | Select ADG407BRZ only if dual-supply operation is unnecessary and tighter RDS(ON) matching is not required. |
| MAX4617ESE+ | Dual SPST configuration (not 8:1); lower RDS(ON) (60Ω typ); no address decoding; requires external logic | Used in discrete-switch applications like relay replacement or power-domain isolation, not channel multiplexing | Choose MAX4617ESE+ only for simple on/off control of individual lines - not for addressable multi-channel routing. |
Compared with ADG407BRZ and MAX4617ESE+, the DG407CWI+T uniquely delivers guaranteed channel matching, dual-supply flexibility, and integrated 3-bit decoding - making it the only option for precision multi-sensor acquisition where inter-channel consistency is mandatory.

FAQ
What is the operating temperature range for DG407CWI+T?
The DG407CWI+T is rated for 0°C to +70°C ambient operation. This commercial-grade temperature range is validated per the device's ordering code 'C' suffix and applies to all electrical specifications unless otherwise noted in the datasheet. The package is a 28-pin Wide SO (W28+6) with RoHS-compliant finish.
Does DG407CWI+T support single-supply operation?
Yes, DG407CWI+T supports single-supply operation from +5V to +30V. In this mode, V− must be connected to GND. The analog signal range remains rail-to-rail (0V to V+), and all key specs - including on-resistance (≤100Ω), charge injection (≤15pC), and leakage (<5nA at +85°C) - are guaranteed across the full supply and temperature range.
Is DG407CWI+T pin-compatible with the original DG407?
Yes, DG407CWI+T is a pin-compatible plug-in upgrade for the industry-standard DG407. It retains identical pinout, footprint, and logic behavior while improving key parameters: guaranteed channel matching (≤8Ω), flatter on-resistance (≤9Ω), and lower charge injection (≤15pC). No PCB or firmware modifications are needed.
What is the maximum analog signal voltage supported by DG407CWI+T?
DG407CWI+T supports analog signals from V− to V+ - i.e., rail-to-rail operation. With ±15V dual supplies, the full range is ±15V; with ±10V, it is ±10V. Absolute maximum analog voltage is limited by the supply rails per the Absolute Maximum Ratings: signals must stay within (V− − 2V) to (V+ + 2V) to avoid diode conduction and potential damage.
How does DG407CWI+T handle power-supply sequencing?
DG407CWI+T requires strict power-supply sequencing: V+ must be applied first, then V−, followed by logic inputs and analog signals. Violating this order risks latch-up or permanent damage. If controlled sequencing is impractical, external series diodes (as shown in Figure 1 of the datasheet) provide overvoltage protection - reducing usable analog range by ~1V but preserving all key switch performance metrics.
