Product details
Overview
DG612DY-E3 from Vishay Siliconix is a high-speed, low-glitch quad SPST analog switch IC with 12 ns turn-on time, 18 Ω on-resistance, and ±2 pC charge injection-designed for fast sample-and-hold, pixel-rate video switching, and DAC deglitching in precision analog signal paths.
For engineers reviewing the DG612DY-E3 datasheet, DG612DY-E3 pinout, DG612DY-E3 application, or DG612DY-E3 equivalent, key selection criteria include bipolar supply support (V+ = 5–21 V, V− = −10 to 0 V), 500 MHz bandwidth, logic-level compatibility (VIH ≥ 4 V, VIL ≤ 1 V), and SOIC-16 packaging for space-constrained PCB layouts.
Technical Context
The DG612DY-E3 implements four independent SPST switches using Vishay's proprietary D/CMOS process-integrating n-channel DMOS FETs with low-power CMOS control logic and on-chip level translators. Each switch conducts bidirectionally when on and blocks up to 16 Vp-p when off.
It features matched on-resistance (ΔRDS(on) ≤ 2 Ω), ultra-low leakage (±0.001 nA typical off-state), and minimized parasitic capacitance (CS(on) = 10 pF, CD(off) = 2 pF) to ensure clean, fast switching with minimal glitch energy and aperture uncertainty.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Turn-On Time | 12 ns at RL = 300 Ω, CL = 3 pF - enables sub-100 ns settling in high-speed sampling systems |
| On-Resistance | 18 Ω typical at V+ = 15 V, V− = −3 V - ensures low insertion loss and minimal signal attenuation |
| Charge Injection | ±2 pC - reduces step-induced offset errors in sample-and-hold and switched-capacitor circuits |
| Bandwidth | 500 MHz - supports pixel-rate video and RF signal routing without high-frequency roll-off |
| Analog Signal Range | V− to (V+ − 5) V - allows full rail-to-rail analog operation with 5 V headroom for linear switching |
| Logic Compatibility | 5 V CMOS - interfaces directly with standard microcontroller GPIOs without level-shifting |
| Supply Range | V+ = 5–21 V, V− = −10 to 0 V - supports dual-supply precision instrumentation and unipolar/bipolar configurations |
Pinout & Package
DG612DY-E3 is housed in a 16-pin narrow SOIC package (JEDEC MS-012, 3.9 × 9.9 mm footprint) with 1.27 mm pitch, RoHS-compliant matte tin terminations (E3 suffix), and thermal derating of 6 mW/°C above 75 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-high logic: INx = 1 → corresponding switch ON (DG612 logic polarity) |
| S1–S4 | Source terminals | Low-impedance analog input nodes; bidirectional conduction when switch is closed |
| D1–D4 | Drain terminals | Low-impedance analog output nodes; matched RDS(on) and capacitance to Sx pins |
| V+, V− | Analog power rails | Support bipolar operation; V+ up to +21 V, V− down to −19 V relative to GND |
| GND | Ground reference | Common return for digital logic and analog substrate; isolated from power supplies |
| VL | Logic supply | Separate 4–V+ V rail for CMOS input stage-decouples logic noise from analog path |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional analog conduction | Equal RDS(on) in both directions enables flexible signal routing without polarity constraints |
| Low charge injection (±2 pC) | Minimizes hold-step error in precision sample-and-hold circuits, eliminating post-switching correction |
| 500 MHz bandwidth | Preserves signal integrity for composite video, RGB, and baseband RF signals up to UHF |
| Separate VL supply pin | Allows independent logic voltage scaling (e.g., 3.3 V control with ±12 V analog rails) for mixed-voltage systems |
| Epitaxial latch-up protection | Guarantees robust operation under transient overvoltage and ESD stress per JEDEC JESD22-A114 |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612ESE+ | Higher RDS(on) (35 Ω typ), slower tON (25 ns), no separate VL pin | Limited to unipolar supplies; less suitable for precision bipolar sample-and-hold | Prefer DG612DY-E3 where low charge injection and dual-supply flexibility are required |
| ADG1412BRUZ | Lower RDS(on) (1.3 Ω), but higher charge injection (±12 pC), 16-bit DAC-compatible | Better for low-distortion audio; worse for fast settling due to higher Q | Choose DG612DY-E3 for video and RF timing-critical paths; ADG1412 for DC-precision instrumentation |
Compared with MAX4612ESE+ and ADG1412BRUZ, DG612DY-E3 uniquely balances ultra-fast switching, ultra-low charge injection, and true bipolar analog operation-making it optimal for pixel-rate video, GaAs driver, and high-fidelity sample-and-hold designs where timing integrity and transient suppression are non-negotiable.

FAQ
What is the logic polarity of DG612DY-E3 compared to DG611DY-E3?
DG612DY-E3 uses active-high logic: INx = 1 (≥4 V) turns the corresponding switch ON. In contrast, DG611DY-E3 uses active-low logic (INx = 0 turns switch ON). This complementary behavior allows identical hardware to support either polarity via firmware or external inverters-DG612DY-E3 is selected when direct positive-logic control is required without inversion.
Can DG612DY-E3 operate from a single 5 V supply?
Yes, DG612DY-E3 supports unipolar operation: set V+ = 5 V, V− = GND, VL = 5 V, and limit analog signals to 0–2 V (per VANALOG = V− to (V+ − 5) V). However, full performance-including 500 MHz bandwidth and minimal distortion-is achieved only with bipolar supplies (e.g., V+ = +15 V, V− = −3 V). For 5 V-only systems, verify RDS(on) and bandwidth meet your signal fidelity requirements.
What is the maximum allowable analog signal voltage swing for DG612DY-E3?
The absolute maximum analog signal range is V− to (V+ − 5) V. For example, with V+ = 15 V and V− = −3 V, the safe analog span is −3 V to +10 V (13 Vp-p). Exceeding this range risks clamping by internal diodes and increased leakage. The device blocks up to 16 Vp-p when OFF, but continuous operation must stay within the recommended analog range to guarantee linearity and low distortion.
Does DG612DY-E3 require external pull-up or pull-down resistors on its INx pins?
No-DG612DY-E3 has CMOS-compatible inputs with IIN ≤ ±1 µA over temperature, so it can be driven directly by microcontroller GPIOs, FPGA outputs, or logic gates without external biasing. Pull-ups/pull-downs are only needed if the driving source floats during reset or power-up; in such cases, 10–100 kΩ resistors to VL or GND ensure defined switch states during initialization.
How does the separate VL pin improve system performance in DG612DY-E3?
The VL pin decouples the logic interface from analog supplies, allowing independent optimization: e.g., VL = 3.3 V for low-noise MCU interfacing while V+ = ±12 V powers high-dynamic-range analog paths. This separation prevents digital switching noise from coupling into sensitive analog nodes-reducing crosstalk by up to 10 dB and improving SNR in mixed-signal systems using DG612DY-E3.
