Product details

Overview

DG611AEY-T1-E3 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, designed for precision signal routing in high-bandwidth, low-distortion applications. It delivers 1 pC typical charge injection, 2 pF off-capacitance, 720 MHz 3 dB bandwidth, and operates from ±5 V dual or +3 V/+5 V single supplies across –40 °C to +125 °C. It is used in medical instrumentation front-ends and automated test equipment multiplexing stages.

For engineers reviewing the DG611AEY-T1-E3 datasheet, DG611AEY-T1-E3 pinout, DG611AEY-T1-E3 application, or DG611AEY-T1-E3 equivalent, key selection criteria include rail-to-rail analog signal handling, guaranteed 2 V logic-high threshold at +5 V supply, leakage < 0.25 nA at 85 °C, and SOIC-16 package compatibility with legacy PCB layouts.

Technical Context

The DG611AEY-T1-E3 implements four independent, bidirectional analog switches with complementary CMOS control architecture. Each switch exhibits symmetrical on-resistance (72 Ω typ. at ±5 V), matched R_ON (≤4 Ω max. variation), and flat R_FLATNESS (≤40 Ω) over full signal range - enabling accurate signal gain/attenuation without distortion.

Its dynamic performance is defined by fast switching (t_ON/t_OFF = 27 ns/16 ns), high isolation (–62 dB at 10 MHz), and low crosstalk (–90 dB at 10 MHz), all verified under dual-supply (±5 V) and single-supply (+5 V, +3 V) conditions per Vishay Document 69904 Rev. C.

Key Specifications

Parameter	Value and Actual Design Meaning
Switch Type	Quad SPST, normally closed (NC) - all four switches conduct when control input is logic low.
Charge Injection	1 pC typical - minimizes voltage glitch in sample-and-hold and precision ADC input stages.
Off Capacitance (C_S(off))	2 pF typical - preserves high-frequency signal integrity and reduces feedthrough in RF/mixed-signal paths.
3 dB Bandwidth	720 MHz - supports high-speed serial data routing, video switching, and wideband instrumentation signals.
On-Resistance (R_ON)	72 Ω typical at ±5 V - ensures low insertion loss and minimal gain error in precision amplifier signal paths.
Leakage Current	< 0.25 nA at 85 °C - critical for maintaining accuracy in high-impedance sensor interfaces and long-integration-time systems.
Supply Range	±2.7 V to ±5 V dual or +2.7 V to +12 V single - enables operation in battery-powered, industrial, and mixed-voltage systems.

Pinout & Package

Package: 16-pin narrow SOIC (JEDEC MS-012), body size 9.9 mm × 3.9 mm × 1.45 mm, lead pitch 1.27 mm, RoHS-compliant, halogen-free.

Pin	Circuit Role	Design Meaning
1, 2, 3, 4	IN1–IN4	Digital control inputs - TTL/CMOS-compatible; logic low enables NC switch conduction.
5, 7, 10, 12	S1–S4	Source terminals - connect to analog signal source; bidirectional conduction supported.
6, 8, 11, 13	D1–D4	Drain terminals - connect to analog signal load; fully rail-to-rail capable (V₋ to V₊).
9	GND	Analog/digital ground reference - must be low-impedance; decoupling required near V+ and V− pins.
14	V−	Negative supply rail - supports dual-supply operation down to −5 V; clamped internally.
15	V+	Positive supply rail - supports up to +12 V single or +5 V dual; internal ESD protection diodes.
16	NC	No connect - internally unconnected; must remain floating or tied to GND per layout guidelines.

Key Features

Feature	Design Value
Rail-to-rail analog signal handling	Supports full-swing signals from V− to V+, eliminating level-shifting in ±5 V or +3 V systems.
Low charge injection (1 pC typ.)	Reduces settling error in precision sampling circuits, enabling sub-16-bit ADC accuracy without recalibration.
High off-isolation (–62 dB @ 10 MHz)	Prevents signal coupling between inactive channels in multi-channel DAQ and ATE systems.
Guaranteed logic thresholds	2 V min. logic-high at +5 V supply ensures reliable interface with 3.3 V microcontrollers and FPGAs.
Extended temperature range	Specified from –40 °C to +125 °C - qualified for under-hood automotive sensors and industrial PLC I/O modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad SPST analog switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4611ESE+	Higher R_ON (125 Ω max), lower bandwidth (300 MHz), no guaranteed 2 V logic-high threshold at +5 V.	Better suited for cost-sensitive industrial controls where speed and precision are secondary.	Select MAX4611ESE+ only if board space allows SOIC-16 footprint and system tolerates higher on-resistance drift.
ADG1411BRUZ	Lower charge injection (0.2 pC), higher supply voltage limit (+36 V), but larger TSSOP-16 package and no miniQFN option.	Ideal for high-voltage test fixtures and isolated sensor interfaces requiring extended voltage margin.	Choose ADG1411BRUZ when operating beyond ±12 V or when ultra-low charge injection dominates over package size constraints.

Compared with MAX4611ESE+ and ADG1411BRUZ, DG611AEY-T1-E3 offers optimal balance of speed (720 MHz), precision (1 pC), and compact SOIC-16 fit - making it preferred for space-constrained, high-fidelity instrumentation where rail-to-rail signal swing and low-temperature drift are mandatory.

FAQ

What is the maximum supply voltage rating for DG611AEY-T1-E3?

DG611AEY-T1-E3 has an absolute maximum V+ to V− rating of 14 V. It is fully specified for operation from ±2.7 V to ±5 V dual supplies or +2.7 V to +12 V single supplies. Exceeding ±5 V or +12 V risks permanent damage, and operation above these limits voids parametric guarantees per Vishay Document 69904 Rev. C.

Does DG611AEY-T1-E3 support rail-to-rail analog signal switching?

Yes, DG611AEY-T1-E3 supports true rail-to-rail analog signal handling - signals from V− to V+ pass through the switch with minimal distortion. This is confirmed in the Analog Signal Range specification (–5 V to +5 V under ±5 V dual supply, 0 V to +5 V under +5 V single supply), and is enabled by its fully enhanced CMOS process design.

What is the logic behavior of DG611AEY-T1-E3 control inputs?

DG611AEY-T1-E3 is a normally closed (NC) quad SPST switch: logic low (≤0.8 V at +5 V supply) turns the switch ON (conducting), and logic high (≥2 V at +5 V supply) turns it OFF (open). This behavior is explicitly defined in the Truth Table for DG611A in Document 69904 Rev. C and applies identically to DG611AEY-T1-E3.

Is DG611AEY-T1-E3 compatible with +3 V logic controllers?

Yes, DG611AEY-T1-E3 is compatible with +3 V logic systems: its input high threshold is guaranteed ≥1.4 V at +3 V supply, ensuring reliable recognition of standard 3.3 V CMOS logic levels. Input current remains below ±0.1 µA across temperature, minimizing loading on microcontroller GPIOs.

What package type does DG611AEY-T1-E3 use, and is it lead-free?

DG611AEY-T1-E3 uses a 16-pin narrow SOIC package (JEDEC MS-012), with dimensions 9.9 mm × 3.9 mm × 1.45 mm. It is RoHS-compliant and lead-free, as confirmed by the "-E3" suffix per Vishay's ordering nomenclature and compliance documentation (Document 69904 Rev. C, Page 1).
