Product details

Overview

DG612AEY-T1-E3 from Vishay Siliconix is a quad SPST analog switch with normally open configuration, designed for precision signal routing in high-speed and low-leakage applications. It delivers 115 Ω max on-resistance at ±5 V, 1 pC typical charge injection, 720 MHz 3 dB bandwidth, and operates across -40 °C to +125 °C - ideal for automated test equipment and medical instrumentation front-end signal paths.

For engineers reviewing the DG612AEY-T1-E3 datasheet, DG612AEY-T1-E3 pinout, DG612AEY-T1-E3 application, or DG612AEY-T1-E3 equivalent, key selection criteria include rail-to-rail analog handling, sub-100 pA leakage at 85 °C, dual-supply (±2.7 V to ±5 V) or single-supply (2.7 V to 12 V) compatibility, and guaranteed 2 V logic-high threshold at +5 V/±5 V operation.

Technical Context

The DG612AEY-T1-E3 implements four independent, bidirectional SPST switches with complementary logic control (logic '0' = off, '1' = on), optimized for minimal signal distortion in both directions. Its CMOS/TTL-compatible inputs support 2.5 V logic levels, and internal protection diodes clamp analog signals exceeding V+ or V−.

Specified fully at +3 V, +5 V, and ±5 V supplies, it maintains <0.25 nA leakage at 85 °C and achieves 27 ns turn-on / 16 ns turn-off times under RL = 300 Ω, CL = 35 pF conditions - enabling use in high-fidelity sample-and-hold and data acquisition systems requiring fast settling and low crosstalk (-90 dB at 10 MHz).

Key Specifications

Parameter	Value and Actual Design Meaning
Analog Signal Range	Rail-to-rail: -5 V to +5 V (dual supply) or 0 V to +5 V (single supply) - supports full dynamic range of connected ADCs or amplifiers without level-shifting.
On-Resistance (RON)	≤115 Ω max at ±5 V, IS = 1 mA - ensures minimal gain error and voltage drop in precision sensor or DAC output switching.
Charge Injection	1 pC typical - reduces pedestal error in sample-and-hold circuits and preserves DC accuracy in high-resolution data acquisition.
3 dB Bandwidth	720 MHz - enables clean switching of RF or high-speed digital clock signals up to ~450 Mbps without significant attenuation.
Off Isolation	-62 dB at 10 MHz - suppresses coupling between inactive channels, critical for multi-channel multiplexed instrumentation.
Leakage Current	<0.25 nA at 85 °C - prevents drift in high-impedance sensor interfaces and long-integration-time measurement systems.
Supply Range	Single: 2.7 V to 12 V; Dual: ±2.7 V to ±5 V - allows flexible integration into mixed-voltage industrial and portable systems.

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
IN1–IN4	Digital control input	Active-high logic inputs controlling respective switches; guaranteed 2 V high threshold at +5 V/±5 V supply.
S1–S4	Switch source terminal	Analog input node for each SPST switch; bidirectional, rail-to-rail capable, clamped by internal ESD diodes.
D1–D4	Switch drain terminal	Analog output node; electrically identical to Sx in conduction, matched capacitance (CS(off) = CD(off) ≈ 2–3 pF).
V+	Positive supply rail	Accepts 2.7–12 V (unipolar) or +2.7 to +5 V (bipolar); powers internal logic and switch driver circuitry.
V−	Negative supply rail	Required for dual-supply operation (−2.7 to −5 V); enables true bipolar analog signal handling.
GND	Ground reference	Logic ground and substrate reference; separate from analog return paths in layout-sensitive designs.
NC	No-connect	Internally unconnected pin; must be left floating or tied to GND per PCB layout best practices.

Key Features

Feature	Design Value
Rail-to-rail analog signal handling	Supports full-swing signals from V− to V+ without clipping or distortion, preserving integrity in wide-dynamic-range systems.
Low charge injection (1 pC typ.)	Minimizes voltage glitch on hold capacitors, directly improving DC accuracy and settling time in precision sample-and-hold stages.
High off-isolation (−62 dB @ 10 MHz)	Prevents signal bleed-through between channels during multiplexing, essential for multi-sensor data acquisition with >80 dB SNR.
Fast switching (27 ns ton / 16 ns toff)	Enables high-throughput channel scanning at >10 MSPS in automated test equipment without timing bottlenecks.
Extended temperature range (−40 °C to +125 °C)	Validated for under-hood automotive, industrial PLC, and downhole instrumentation where ambient thermal stress exceeds commercial limits.

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
MAX4612ESE+	Higher R_ON (180 Ω max), lower bandwidth (300 MHz), wider SOIC package (5.3 mm vs. 3.9 mm).	Less suitable for >500 kSPS data acquisition due to slower settling and higher distortion.	Choose when cost sensitivity outweighs speed/leakage requirements and board space permits larger footprint.
ADG1412BRUZ	Lower leakage (10 pA typ. at 25 °C), but narrower temp range (−40 °C to +105 °C), no 125 °C rating.	Not qualified for extended-temperature industrial or automotive under-hood use.	Prefer for ultra-low-leakage lab-grade instruments where 125 °C operation is unnecessary.

Compared with MAX4612ESE+ and ADG1412BRUZ, DG612AEY-T1-E3 uniquely balances 1 pC charge injection, 720 MHz bandwidth, and full −40 °C to +125 °C qualification - making it optimal for high-reliability, high-fidelity multiplexing where thermal robustness and signal integrity are co-critical.

FAQ

What is the maximum supply voltage rating for DG612AEY-T1-E3?

The absolute maximum rating for DG612AEY-T1-E3 is V+ to V− = 14 V. For continuous operation, it is fully specified at single supplies from 2.7 V to 12 V and dual supplies from ±2.7 V to ±5 V. Exceeding ±5 V on dual rails or 12 V on single supply risks permanent damage per Absolute Maximum Ratings table.

Does DG612AEY-T1-E3 support rail-to-rail analog signal switching?

Yes, DG612AEY-T1-E3 supports true rail-to-rail analog signal handling: signals can swing from V− to V+ without clipping. This is confirmed in the "Analog Signal Range" specification (−5 V to +5 V for dual supply, 0 V to +5 V for single supply), and applies to all four SPST switches in the DG612AEY-T1-E3 device.

What is the logic polarity of DG612AEY-T1-E3 control inputs?

DG612AEY-T1-E3 has active-high logic control: a logic '1' (≥2 V at +5 V/±5 V supply, ≥1.4 V at +3 V supply) turns the corresponding switch ON, and a logic '0' turns it OFF. This is defined in the Truth Table for DG612A and verified across all operating conditions in the Digital Control section of the datasheet.

Can DG612AEY-T1-E3 operate from a single 3 V supply?

Yes, DG612AEY-T1-E3 is fully specified for single-supply operation at +3 V (V− = 0 V). At this supply, it delivers analog signal range 0 V to +3 V, on-resistance ≤300 Ω max, charge injection 2.3 pC, and 550 MHz 3 dB bandwidth - all validated over −40 °C to +125 °C per the Unipolar Supplies (V+ = +3 V) specifications table.

Is DG612AEY-T1-E3 pin-compatible with older DG612 variants?

Yes, DG612AEY-T1-E3 shares identical pinout, package (16-pin narrow SOIC), and electrical behavior with legacy DG612 versions including DG612Y. The 'A' suffix denotes improved performance (e.g., lower charge injection, tighter R_ON matching), but mechanical and functional compatibility is maintained - allowing direct replacement in existing designs without layout changes.
