Product details
Overview
DG407EWI+ from Maxim Integrated is a dual 8-channel CMOS analog multiplexer/demultiplexer designed for precision signal routing in mixed-signal 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. Used in data-acquisition systems requiring channel-to-channel signal integrity and rail-to-rail analog handling.
For engineers reviewing the DG407EWI+ datasheet, DG407EWI+ pinout, DG407EWI+ application, or DG407EWI+ equivalent, key selection criteria include guaranteed on-resistance matching across channels, low temperature drift of leakage current (<5nA at +85°C), TTL/CMOS-compatible digital control, and ESD robustness (>2000V per MIL-STD 883 Method 3015.7).
Technical Context
The DG407EWI+ implements a dual independent 8:1 analog switch architecture with separate address decoding (A0–A2) and enable (EN) per 8-channel bank. Each channel conducts bidirectionally with matched RDS(ON) and minimal flatness variation over the full ±10V analog signal range.
Its internal CMOS switch design guarantees low charge injection (≤15pC) and input off-leakage <5nA at +85°C, enabling accurate sample-and-hold operation. Digital inputs are TTL/CMOS-compatible, and rail-to-rail signal handling supports full-supply-range analog switching without clipping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 100Ω - Ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Matching (max) | 8Ω - Guarantees consistent gain/attenuation across all 16 channels for multi-channel measurement accuracy |
| On-Resistance Flatness (max) | 9Ω - Maintains stable impedance across entire ±10V analog input range, critical for linearity |
| Charge Injection (max) | 15pC - Limits sampling error in high-impedance hold capacitors (e.g., 10pF cap yields ≤1.5V glitch) |
| Input Off-Leakage (max) | 5nA at +85°C - Preserves signal integrity in high-Z sensor interfaces and long-hold intervals |
| Supply Range | ±4.5V to ±20V dual or +5V to +30V single - Supports industrial, test, and wide-voltage embedded systems |
| ESD Protection | >2000V per MIL-STD 883 Method 3015.7 - Enables robust handling in manufacturing and field environments |
Pinout & Package
Package: 28-pin Wide SO (W28+6), RoHS-compliant, -40°C to +85°C operating range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | DB | Bidirectional analog output for Bank B - Connects to common node for S1B–S8B channels |
| 3,13,14 | N.C. | No internal connection - Leave unconnected; no pull-up/down required |
| 4–11 | S8B–S1B | Bidirectional analog inputs for Bank B - Selected via A0–A2 and ENB (shared EN) |
| 12 | GND | Ground reference - Common return for logic and analog sections; decoupling critical |
| 15–17 | A2, A1, A0 | Binary address inputs - Select one of eight channels per bank; TTL/CMOS compatible |
| 18 | EN | Enable input - Active-high; disables both banks when low, reducing leakage and power |
| 19–26 | S1A–S8A | Bidirectional analog inputs for Bank A - Independent selection from Bank B |
| 27 | V- | Negative supply rail - Powers analog core; must be sequenced after V+ |
| 28 | DA | Bidirectional analog output for Bank A - Common node for S1A–S8A switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG407BRZ | Higher on-resistance (120Ω max), wider temp range (−40°C to +125°C), same 28-SO package | Better suited for automotive under-hood use; less optimal for low-distortion audio due to higher RON | Select ADG407BRZ only if extended temperature or AEC-Q200 compliance is required |
| TS5A23157DGSR | Single-supply only (+1.65V to +5.5V), lower voltage rating, 10Ω typical RON, 8-pin package | Targeted at portable, low-voltage, space-constrained designs - not a functional or pin replacement | Choose TS5A23157DGSR only for battery-powered, 3.3V/5V systems where dual-supply operation is unnecessary |
Compared with ADG407BRZ and TS5A23157DGSR, the DG407EWI+ uniquely delivers guaranteed on-resistance matching (≤8Ω) and flatness (≤9Ω) across its full ±20V dual-supply range - a combination not replicated by either alternative, making it essential for precision instrumentation requiring channel consistency.

FAQ
What is the operating temperature range of the DG407EWI+?
The DG407EWI+ is rated for operation from −40°C to +85°C. This extended industrial temperature range is validated across all key parameters including on-resistance matching (≤8Ω), leakage current (<5nA at +85°C), and charge injection (≤15pC), ensuring reliability in harsh environments without derating.
Does the DG407EWI+ support single-supply operation?
Yes, the DG407EWI+ supports single-supply operation from +5V to +30V. When used in single-supply mode, V− must be connected to GND. The device maintains rail-to-rail analog signal handling and retains all guaranteed specifications including on-resistance flatness and leakage performance.
Is the DG407EWI+ pin-compatible with the original DG407?
Yes, the DG407EWI+ is a pin-compatible plug-in upgrade for the industry-standard DG407. It uses the identical 28-pin Wide SO footprint and pinout, allowing direct replacement without PCB modification while delivering improved matching, flatness, and leakage specs.
What is the maximum analog signal range supported by the DG407EWI+?
The DG407EWI+ supports an analog signal range from V− to V+, up to ±20V with dual supplies or 0V to +30V with single supply. At ±15V supplies, the guaranteed analog range is ±10V - verified by on-resistance flatness ≤9Ω and leakage <5nA across that span.
How does the enable (EN) pin function in the DG407EWI+?
The EN pin is an active-high enable controlling both 8-channel banks simultaneously. When EN = low, all switches are disabled, reducing off-leakage current and power consumption. When EN = high, channel selection proceeds via A0–A2. The enable turn-on/off times are specified at 105ns to 600ns (tON(EN)) and 80ns to 300ns (tOFF(EN)) under defined load conditions.
