Product details
Overview
DG612AEN-T1-E4 from Vishay Siliconix is a quad SPST analog switch with normally open (NO) configuration, designed for precision signal routing in high-speed and low-leakage applications. It delivers 1 pC typical charge injection, 2 pF source-off capacitance, 720 MHz 3 dB bandwidth, and operates from ±2.7 V to ±5 V dual supplies or +2.7 V to +12 V single supply - ideal for automated test equipment front-end multiplexing.
For engineers reviewing the DG612AEN-T1-E4 datasheet, DG612AEN-T1-E4 pinout, DG612AEN-T1-E4 application, or DG612AEN-T1-E4 equivalent, key selection criteria include rail-to-rail analog signal handling, -40 °C to +125 °C operation, 115 Ω max RDS(on), and compatibility with 1.4 V logic thresholds at +3 V supply.
Technical Context
The DG612AEN-T1-E4 implements four independent, bidirectional SPST switches with complementary control logic: logic high enables conduction (ON), logic low disables (OFF). Its CMOS architecture supports full rail-to-rail analog voltage swing (±5 V dual or 0–5 V single supply) and guarantees 2 V logic-high input threshold at ±5 V/5 V supplies and 1.4 V at +3 V.
Switch performance is characterized by low dynamic distortion (0.01% THD), excellent channel isolation (-62 dB at 10 MHz), and minimal crosstalk (-90 dB at 10 MHz), enabling simultaneous high-fidelity signal switching without interference across channels.
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. |
| RDS(on) Max | 115 Ω at ±5 V dual supply - ensures minimal signal attenuation and gain error in precision DC/low-frequency paths. |
| Charge Injection | 1 pC typical - critical for sample-and-hold accuracy and low glitch in data acquisition front-ends. |
| Bandwidth | 720 MHz 3 dB - supports high-speed communication signals up to UWB and fast digital waveform routing. |
| Leakage Current | < 0.25 nA at +85 °C - preserves signal integrity in high-impedance sensor interfaces and medical instrumentation. |
| Supply Range | ±2.7 V to ±5 V dual or +2.7 V to +12 V single - enables flexible integration into mixed-supply systems without level-shifting. |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and aerospace-grade embedded systems. |
Pinout & Package
Package: 16-pin miniQFN (1.8 mm × 2.6 mm, 0.4 mm pitch), leadless, exposed thermal pad, RoHS-compliant, halogen-free per IEC 61249-2-21.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | CMOS/TTL-compatible; 1.4 V min logic-high threshold at +3 V supply enables direct MCU GPIO interfacing. |
| S1–S4 | Switch sources | Analog inputs - accept rail-to-rail signals from V− to V+; internally clamped to prevent overvoltage damage. |
| D1–D4 | Switch drains | Analog outputs - bidirectional conduction path; matched RDS(on) and flatness ensure channel consistency. |
| V+ | Positive supply | Supports up to +12 V single or +5 V dual; powers internal logic and analog switch core. |
| V− | Negative supply | Required for dual-supply operation down to -5 V; enables true bipolar signal handling. |
| GND | Ground reference | Logic and substrate reference; separate from analog ground plane in layout best practice. |
| NC | No connect | Internally unconnected pin - must be left floating or tied to GND per PCB layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Full signal swing from V− to V+ with no dead zone - eliminates clipping in ±5 V sensor or DAC output paths. |
| Ultra-low charge injection (1 pC) | Minimizes voltage step error during sampling - essential for 16-bit+ data acquisition and precision ADC driver stages. |
| 720 MHz 3 dB bandwidth | Preserves rise/fall times of fast digital or RF-modulated signals - suitable for video switching and high-speed serial muxing. |
| 62 dB off-isolation at 10 MHz | Prevents signal bleed-through between inactive channels - critical for multi-channel ATE and medical EEG/ECG front-ends. |
| 90 dB crosstalk suppression | Ensures channel independence in dense analog routing - avoids inter-channel interference in multi-sensor measurement systems. |
Applications
| Automated Test Equipment (ATE) | Precision Data Acquisition |

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 |
|---|---|---|---|
| MAX4617ESE+ | Higher RDS(on) (180 Ω max), lower bandwidth (300 MHz), same SOIC-16 package. | Limited to lower-speed instrumentation; unsuitable for >500 MHz signal routing. | Select when cost sensitivity outweighs bandwidth/leakage requirements and SOIC footprint is mandatory. |
| ADG1412BRUZ | Lower leakage (15 pA typ. at 25 °C), higher RDS(on) (120 Ω max), TSSOP-16 package. | Better for ultra-low-current biosensing but slower switching (tON/tOFF = 100/75 ns) and reduced bandwidth (500 MHz). | Prefer for sub-nA leakage-critical medical sensors where speed is secondary to DC precision. |
Compared with MAX4617ESE+ and ADG1412BRUZ, DG612AEN-T1-E4 uniquely balances 1 pC charge injection, 720 MHz bandwidth, and 115 Ω RDS(on) in a space-constrained miniQFN package - making it optimal for high-density, high-fidelity signal routing where layout area and AC performance are jointly constrained.

FAQ
What is the logic configuration of DG612AEN-T1-E4?
The DG612AEN-T1-E4 features a normally open (NO) configuration: each of its four SPST switches conducts only when the corresponding INx input is driven logic high. This is confirmed in the truth table on page 2 of Vishay document 69904, where logic '1' yields 'On' for all switches. The DG612AEN-T1-E4 is distinct from the DG611A (normally closed) and DG613A (mixed NO/NC).
Does DG612AEN-T1-E4 support single-supply operation at +3 V?
Yes, DG612AEN-T1-E4 is fully specified for +3 V single-supply operation, with guaranteed performance including 195–300 Ω RDS(on), 2.3 pC charge injection, and 550 MHz bandwidth. Input logic thresholds are 1.4 V (min) for high and 0.6 V (max) for low, ensuring reliable interface with 3 V microcontrollers without level shifters.
What is the thermal pad connection requirement for DG612AEN-T1-E4?
The miniQFN package of DG612AEN-T1-E4 includes an exposed thermal pad on the bottom surface. Per Vishay package drawing 64694, this pad must be soldered to a thermally robust PCB copper area for optimal power dissipation (525 mW max at 25 °C) and junction temperature control. No solder fillet is required at the pad edge due to manufacturing singulation process.
Can DG612AEN-T1-E4 handle analog signals beyond the supply rails?
No - DG612AEN-T1-E4 does not support overvoltage-tolerant operation. Signals on Sx or Dx pins exceeding V+ or falling below V− will be clamped by internal diodes (per Absolute Maximum Ratings note a). Continuous forward current through these diodes must be limited to rated values to avoid damage; external clamping is recommended for overvoltage protection.
Is DG612AEN-T1-E4 pin-compatible with other DG61xA variants in the same package?
Yes - DG612AEN-T1-E4 shares identical pinout and package (miniQFN-16) with DG611AEN-T1-E4 and DG613AEN-T1-E4, as shown in the functional block diagrams on pages 2–3 of document 69904. Only the internal switch logic (NO vs NC vs mixed) differs; no PCB redesign is needed when substituting within the DG61xA family in the same package variant.
