Product details
Overview
DG469EQ-T1-E3 from Vishay Siliconix is a high-voltage, single-pole double-throw (SPDT) analog switch with enable functionality disabled (no EN pin), featuring 3.6 Ω typical on-resistance, ±15 V analog signal range, and guaranteed break-before-make switching. It operates across -40 °C to +125 °C with dual supplies (±4.5 V to ±15 V) or single supply (12 V), and is used in precision audio routing where low distortion and rail-to-rail signal handling are critical.
For engineers reviewing the DG469EQ-T1-E3 datasheet, DG469EQ-T1-E3 pinout, DG469EQ-T1-E3 application, or DG469EQ-T1-E3 equivalent, key selection criteria include on-resistance flatness (0.4 Ω typical), charge injection (58 pC), off-isolation (-57 dB at 1 MHz), and compatibility with TTL/CMOS logic levels at 0.8 V / 2.4 V thresholds.
Technical Context
The DG469EQ-T1-E3 implements a single-channel SPDT topology with symmetrical bidirectional conduction and no enable input-distinguishing it from the DG470 family. Its internal architecture guarantees break-before-make timing (15 ns delay) to prevent channel shorting during transition, and integrates clamping diodes that limit analog inputs to V+ +2 V and V− −2 V.
It supports three supply configurations: ±4.5 V, ±15 V, and +12 V/0 V, with fully characterized performance across all. Signal bandwidth exceeds 100 MHz (off-isolation >57 dB up to 1 MHz), and total harmonic distortion is specified at 0.0145 % under ±15 V dual-supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 3.6 Ω typical at ±15 V - enables low insertion loss in precision signal paths |
| Analog signal range | ±15 V - supports rail-to-rail analog signals without clipping |
| Supply voltage max | 44 V (V+ to V−) - allows robust operation in high-voltage industrial systems |
| Charge injection | 58 pC - minimizes voltage glitch in sample-and-hold and data acquisition |
| Off-isolation (OIRR) | -57 dB at 1 MHz - ensures strong channel separation in video/audio multiplexing |
| Turn-on time (tON) | 129 ns typical (RL = 300 Ω, CL = 35 pF) - suitable for fast-switching video routing |
| Logic threshold | 0.8 V low / 2.4 V high - ensures reliable interfacing with 3.3 V and 5 V CMOS/TTL |
Pinout & Package
Package: 8-pin MSOP (Mini Small Outline Package), 3.0 mm × 3.0 mm body, 0.65 mm pitch, exposed pad for thermal enhancement.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO (Normally Open) | Switch output terminal connected when IN = 1; carries full analog signal range |
| 2 | NC (Normally Closed) | Switch output terminal connected when IN = 0; bidirectional, rail-to-rail capable |
| 3 | GND | Ground reference for digital control and substrate bias; must be low-impedance |
| 4 | V+ | Positive supply rail; supports up to +20 V (absolute max); powers internal logic and analog path |
| 5 | NO/NC common | COM - analog input node; connects to either NO or NC based on IN state |
| 6 | V- | Negative supply rail; supports down to -20 V (absolute max); defines lower analog swing limit |
| 7 | IN | Digital control input; TTL/CMOS compatible; no internal pull-up/down; requires external drive |
| 8 | No Connect | Internally unconnected; must be left floating or tied to GND per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 15 ns minimum delay prevents momentary shorting between NO and NC paths |
| On-resistance flatness | 0.4 Ω typical across ±10 V signal range - maintains consistent gain and linearity in AC-coupled paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4692EUA+ | Higher on-resistance (12 Ω typical), wider temp range (-40 °C to +85 °C only), no MSOP-8 option | Limited to commercial-grade systems; unsuitable for extended temperature automotive or industrial use | Select if cost sensitivity outweighs on-resistance and temperature requirements |
| ADG1419BRMZ | Lower charge injection (12 pC), but higher RON (8.5 Ω typical), requires ±15 V only (no 12 V unipolar support) | Better for ultra-low-glitch sample-and-hold; less flexible for mixed-supply designs | Prefer when charge injection dominates design constraints over signal range or supply flexibility |
Compared with MAX4692EUA+ and ADG1419BRMZ, the DG469EQ-T1-E3 uniquely balances low on-resistance (3.6 Ω), wide supply flexibility (±4.5 V to ±15 V and +12 V), and extended temperature capability (-40 °C to +125 °C) in a compact MSOP-8 package-making it optimal for high-reliability analog routing where signal integrity and operating margin are jointly critical.

FAQ
What is the maximum analog signal voltage range supported by the DG469EQ-T1-E3?
The DG469EQ-T1-E3 supports an analog signal range of ±15 V when operated with dual ±15 V supplies, and up to 0 V to +12 V with single-supply configuration. Absolute maximum analog input is clamped to V− −2 V and V+ +2 V by internal diodes, making the practical safe range ±15 V under standard operating conditions. This range is fully specified and tested per Vishay Document Number 71470.
Does the DG469EQ-T1-E3 have an enable pin like the DG470?
No, the DG469EQ-T1-E3 does not include an enable (EN) pin. It is functionally identical to the DG469 variant described in the datasheet, with only IN, COM, NO, and NC control terminals. The DG470EQ-T1-E3 is the version with enable functionality. Pin 1 in DG469EQ-T1-E3 is NO, whereas DG470EQ-T1-E3 uses Pin 1 as EN-confirming the absence of enable logic in DG469EQ-T1-E3.
What is the typical on-resistance flatness of the DG469EQ-T1-E3 and why does it matter?
The DG469EQ-T1-E3 has a typical on-resistance flatness of 0.4 Ω across the ±10 V analog signal range. This parameter quantifies how consistently RON remains over the signal swing-critical for maintaining amplitude accuracy and minimizing harmonic distortion in AC-coupled or precision DC applications. Low flatness ensures uniform gain and linearity, especially in audio and instrumentation front-ends where channel matching is essential.
Can the DG469EQ-T1-E3 operate from a single 12 V supply?
Yes, the DG469EQ-T1-E3 is fully specified for unipolar 12 V operation (V+ = 12 V, V− = 0 V), supporting analog signals from 0 V to 12 V. In this mode, typical on-resistance is 7.5 Ω, turn-on time is 190 ns, and leakage remains below ±0.5 nA. All dynamic and static parameters are validated per the "Specifications for Unipolar Supplies" section of the DG469/DG470 datasheet (Rev. D).
Is the DG469EQ-T1-E3 RoHS compliant and what package does it use?
Yes, the DG469EQ-T1-E3 is RoHS compliant per Directive 2002/95/EC, as confirmed in the Vishay datasheet (Document Number 71470, Rev. D). It is supplied in an 8-pin MSOP package (3.0 mm × 3.0 mm, 0.65 mm pitch) with an exposed thermal pad, designated by the "EQ" suffix in the part number-distinct from the SOIC-8 "EY" variant.
