Product details
Overview
DG612EEY-T1-GE3 from Vishay Siliconix is a quad SPST analog switch with normally open (NO) configuration, designed for precision signal routing in high-speed, low-distortion applications. It operates from 3 V to 16 V single supply or ±3 V to ±8 V dual supplies, features 1.4 pC typical charge injection, 3 pF off-capacitance, 23 ns turn-on time, and 1 GHz 3 dB bandwidth - enabling use in medical instrumentation and automated test equipment.
For engineers reviewing the DG612EEY-T1-GE3 datasheet, DG612EEY-T1-GE3 pinout, DG612EEY-T1-GE3 application, or DG612EEY-T1-GE3 equivalent, key selection criteria include rail-to-rail analog signal handling, guaranteed 1.4 V logic-high threshold at +3 V supply, -59 dB off-isolation at 10 MHz, and operation across -40 °C to +125 °C.
Technical Context
The DG612EEY-T1-GE3 implements four independent, bidirectional analog switches with complementary CMOS control architecture. Each switch conducts equally well in both directions and supports full rail-to-rail analog voltage swing from V− to V+ under all supply conditions (3–16 V single or ±3–±8 V dual).
Its low 72 Ω typical on-resistance (at ±5 V), matched ΔRDS(on) ≤ 2.5 Ω, and flat Rflat(on) ≤ 20 Ω ensure minimal gain error and channel-to-channel tracking in multiplexed data acquisition systems. Charge injection of 1.4 pC and THD of 0.13% support high-fidelity sampling in precision instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally open (NO) - all four switches conduct only when control input is logic high. |
| Supply Range | 3 V to 16 V single supply or ±3 V to ±8 V dual supply - fully specified at +3 V, +5 V, and ±5 V. |
| On-Resistance | 72 Ω typ. at ±5 V - ensures minimal insertion loss and signal attenuation in analog paths. |
| Charge Injection | 1.4 pC typ. - limits voltage glitch in sample-and-hold and switched-capacitor circuits. |
| Bandwidth | 1 GHz 3 dB - supports high-speed communication and RF signal switching up to UHF. |
| Off-Isolation | -59 dB at 10 MHz - provides strong channel separation in multi-channel instrumentation. |
| Leakage Current | < 0.25 nA max. at 85 °C - preserves accuracy in high-impedance sensor interfaces. |
Pinout & Package
Package: 16-pin narrow SOIC (SO-16 AS), JEDEC MS-012 compliant, body size 9.8 mm × 3.9 mm × 1.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | CMOS/TTL-compatible; guaranteed logic-high threshold of 1.4 V at +3 V supply. |
| S1–S4 | Switch source terminals | Analog inputs/outputs; bidirectional, rail-to-rail capable from V− to V+. |
| D1–D4 | Switch drain terminals | Analog inputs/outputs; electrically identical to S pins; no polarity dependency. |
| V+ | Positive supply | Accepts 3–16 V (single) or +3 to +8 V (dual); internal ESD protection diodes clamp signals exceeding V+. |
| V− | Negative supply | Accepts 0 V (ground) or −3 to −8 V (dual); clamps signals below V− via internal diodes. |
| GND | Ground reference | Logic and analog return; separate from power ground in mixed-signal layouts to reduce noise coupling. |
| NC | No connect | Internally unconnected pin; must be left floating or tied to GND per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full V− to V+ voltage swing without distortion or clipping - critical for wide-dynamic-range sensors. |
| 1.4 pC charge injection | Minimizes hold-mode error in precision sample-and-hold circuits, enabling sub-16-bit accuracy. |
| 3 pF off-capacitance (CS(off)/CD(off)) | Reduces crosstalk and loading on adjacent high-impedance nodes in dense PCB layouts. |
| 23 ns / 14 ns tON/tOFF (±5 V) | Enables >10 MSPS multiplexing in high-speed data acquisition without timing bottlenecks. |
| -74 dB crosstalk at 10 MHz | Preserves signal integrity in multi-channel medical EEG/ECG front-ends where channel isolation is essential. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Quad SPST NO, 3.5 Ω on-resistance (lower), but 25 pC charge injection (18× higher) and 300 MHz bandwidth. | Better for low-RDS(on) DC-coupled power routing; unsuitable for precision sampling due to high charge injection. | Select DG612EEY-T1-GE3 when charge injection & bandwidth dominate; choose MAX4617ESE+ only for ultra-low on-resistance DC paths. |
| ADG1412BRUZ | Quad SPST NO, 1.8 Ω on-resistance, 22 pC charge injection, 170 MHz bandwidth, ±15 V rating. | Higher voltage tolerance and lower RDS(on), but insufficient bandwidth and excessive charge injection for high-speed sampling. | DG612EEY-T1-GE3 is preferred for >100 MHz signal routing and sub-pC sampling fidelity; ADG1412BRUZ suits high-voltage industrial I/O. |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG612EEY-T1-GE3 uniquely balances ultra-low charge injection (1.4 pC), 1 GHz bandwidth, and rail-to-rail operation - making it optimal for precision, high-speed analog multiplexing where signal integrity is non-negotiable.

How does the DG612EEY-T1-GE3 handle analog signals exceeding the supply rails?
The DG612EEY-T1-GE3 includes internal clamping diodes on all S and D pins. Signals exceeding V+ or falling below V− are clamped, provided forward diode current remains within absolute maximum ratings (30 mA continuous, 100 mA pulsed). External series resistors are recommended for overvoltage protection.
What is the significance of the "EEY" suffix in DG612EEY-T1-GE3?
The "EEY" denotes Vishay's narrow-body 16-pin SOIC package (SO-16 AS, JEDEC MS-012), distinct from TSSOP ("EEQ") and miniQFN ("EEN") variants. The "T1" indicates tape-and-reel packaging, and "GE3" specifies RoHS-compliant, lead-free, halogen-free finish per Vishay standard.
Can the DG612EEY-T1-GE3 be used in bidirectional analog signal paths?
Yes, the DG612EEY-T1-GE3 is fully bidirectional: its S and D terminals are functionally identical, with symmetrical on-resistance, capacitance, and leakage characteristics - allowing seamless use in either direction without performance degradation or signal polarity constraints.
