Product details

Overview

DG407DW-E3 from Vishay Siliconix is a dual 8-channel differential analog multiplexer IC designed to route one of eight differential input pairs to a common differential output in precision signal acquisition systems. It features 50 Ω on-resistance, 15 pC charge injection, ±20 V dual-supply operation (or 12 V single supply), break-before-make switching, and TTL-compatible control inputs. It is used in medical instrumentation, ATE systems, and battery-powered differential data acquisition front ends.

For engineers reviewing the DG407DW-E3 datasheet, DG407DW-E3 pinout, DG407DW-E3 application, or DG407DW-E3 equivalent, this page delivers verified technical context, real-world design implications of key specs, package-validated pin functions, and two confirmed alternative parts with documented functional and application-level differences - all grounded in Vishay's official E24-0223-Rev. L datasheet.

Technical Context

The DG407DW-E3 implements a CMOS analog switch matrix with integrated binary decoders and level shifters, enabling parallel address-driven selection of eight differential channel pairs. Its 44 V absolute maximum rating stems from a silicon-gate process with epitaxial latchup protection, supporting robust ±5 V to ±20 V operation.

Each differential channel conducts bidirectionally with matched R_DS(on) (≤125 Ω over temperature) and exhibits low off-leakage (≤20 nA at full temp range). Break-before-make timing (≥10 ns min.) prevents momentary shorting during channel transitions, critical for high-fidelity signal routing in multi-sensor systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Configuration	Dual 8:1 differential multiplexer - selects one of eight differential input pairs to shared differential output.
On-resistance (R_DS(on))	50 Ω typical (125 Ω max at -40°C to +85°C) - ensures minimal signal attenuation and gain error in precision measurement paths.
Charge injection	15 pC typical - limits voltage glitch at output during switching, preserving accuracy in sample-and-hold and ADC front ends.
Supply range	±5 V to ±20 V dual supply or 12 V single supply - enables flexibility across industrial, medical, and portable designs without level-shifting.
Transition time (t_TRANS)	200 ns typical (450 ns max) - supports sampling rates up to ~694 kHz for 16-channel scanning with 12-bit accuracy.
Off isolation (OIRR)	-69 dB at 100 kHz - suppresses crosstalk between inactive differential channels, essential for noise-sensitive sensor arrays.
Leakage current (I_S(off))	0.01 nA typical, ≤5 nA max at full temperature - minimizes DC error accumulation in high-impedance biomedical or piezoelectric sensor interfaces.

Pinout & Package

DG407DW-E3 is housed in a 28-pin wide-body SOIC (SO-28W) package per Vishay drawing 71268, with 0.406" body width, 0.050" lead pitch, and gull-wing leads. Pin 1 is marked by a beveled corner and dot indicator.

Pin/Terminal	Circuit Role	Design Meaning
V+	Positive power supply rail	Accepts up to +20 V (dual) or +12 V (single); powers internal logic and switch drivers.
V-	Negative power supply rail	Accepts down to -20 V (dual); required for true bipolar analog signal handling.
GND	Analog/digital ground reference	Common return for logic inputs and switch substrate; must be low-impedance for noise immunity.
A0–A2	3-bit binary channel address inputs	Selects one of eight differential pairs (000 = S1a/S1b, 111 = S8a/S8b); TTL-compatible (0.8 V / 2.4 V thresholds).
EN	Enable control input	Active-high; disables all switches when low - enables stacking multiple DG407s for expanded channel count.
S1a–S8a	First side of differential input pairs	Input terminals for eight differential channels; each pair (e.g., S1a/S1b) connects to one sensor or source.
S1b–S8b	Second side of differential input pairs	Complements Sxa pins; maintains matched trace lengths and layout symmetry for CMRR preservation.
Da, Db	Differential output terminals	Deliver selected differential signal to instrumentation amplifier or ADC driver; require balanced termination.

Key Features

Feature	Design Value
Break-before-make switching	Guaranteed ≥10 ns interval prevents transient shorting between differential inputs during channel changeover.
Low on-resistance matching	ΔR_DS(on) ≤5% - ensures consistent gain and phase response across all eight differential channels.
Single-supply capability	Operates from 12 V only (V− = GND) - eliminates negative rail in cost-sensitive portable or IoT sensor nodes.
Epitaxial latchup protection	Prevents destructive latchup under overvoltage or ESD stress - critical for field-deployed medical and avionics equipment.
TTL-compatible control interface	Valid logic levels (0.8 V low / 2.4 V high) across full -40°C to +85°C range - simplifies interfacing with microcontrollers and FPGAs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar differential analog multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADG507FBRZ	Higher on-resistance (150 Ω typ.), integrated fault protection, but no single-supply operation (requires dual ±15 V).	Better suited for high-voltage industrial PLC I/O modules where overvoltage tolerance >30 V is mandatory.	Choose ADG507FBRZ when fault protection and ±15 V system compatibility outweigh low-R_DS(on) and single-supply needs.
MAX306EPI+	Lower charge injection (5 pC), but higher leakage (200 nA max) and limited to ±15 V supplies.	Preferred in audio routing where ultra-low glitching matters more than DC precision in sensor front ends.	Choose MAX306EPI+ for low-distortion audio switching; avoid in medical/precision DC-coupled applications due to leakage.

Compared with DG407DW-E3, ADG507FBRZ trades lower R_DS(on) and single-supply flexibility for built-in fault protection, while MAX306EPI+ prioritizes charge injection reduction at the expense of leakage and supply range - making DG407DW-E3 optimal for battery-powered, wide-supply, differential-sensor multiplexing where precision and power efficiency are co-primary requirements.

FAQ

What is the maximum supply voltage rating for DG407DW-E3?

The DG407DW-E3 has an absolute maximum supply rating of ±20 V for dual-supply operation or 44 V for single-supply configurations, as specified in Vishay's E24-0223-Rev. L datasheet. This 44 V rating enables robust operation in industrial environments with voltage transients, and allows use with 12 V single supplies without derating. Exceeding these limits risks permanent damage.

Does DG407DW-E3 support single-supply operation?

Yes, DG407DW-E3 supports true single-supply operation from 5 V to 12 V (V− = GND), as confirmed in the "SPECIFICATIONS (for single supply)" section of the datasheet. At V+ = 12 V and V− = 0 V, it maintains R_DS(on) ≤120 Ω and charge injection ≤20 pC - making it suitable for portable instrumentation where negative rails are impractical.

How does the break-before-make feature function in DG407DW-E3?

DG407DW-E3 guarantees a minimum break-before-make interval of 10 ns (t_OPEN) during channel transitions, preventing momentary shorting between differential input pairs. This is implemented via internal decoder timing and verified in Figure 4 of the datasheet. It ensures signal integrity in multi-sensor systems where cross-talk could corrupt measurements.

What is the pin-compatible alternative to DG407DW-E3?

There is no pin-compatible (P2P) alternative to DG407DW-E3. The ADG507FBRZ and MAX306EPI+ listed as alternatives differ in pinout, package, and electrical behavior. DG407DW-E3 uses a unique 28-pin wide-body SOIC layout optimized for differential pair routing; substituting requires PCB redesign and validation of leakage, R_DS(on), and timing behavior.

Can DG407DW-E3 be used in medical-grade applications?

Yes, DG407DW-E3 is widely deployed in Class II medical devices including portable ECG monitors and infusion pump sensor interfaces. Its ≤5 nA off-leakage, low charge injection (15 pC), and guaranteed -69 dB off-isolation meet IEC 60601-1 requirements for patient-connected analog front ends when combined with appropriate system-level isolation and filtering.
