Product details
Overview
DG611AEN-T1-E4 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, designed for precision signal routing in high-bandwidth applications. It delivers 1 pC typical charge injection, 2 pF off-capacitance, 720 MHz 3 dB bandwidth, and rail-to-rail analog signal handling across ±5 V or +3 V/+5 V supplies - ideal for automated test equipment input multiplexing.
For engineers reviewing the DG611AEN-T1-E4 datasheet, DG611AEN-T1-E4 pinout, DG611AEN-T1-E4 application, or DG611AEN-T1-E4 equivalent, key selection criteria include guaranteed 115 Ω max RON at ±5 V, -40 °C to +125 °C operation, 16-pin miniQFN (1.8 mm × 2.6 mm) package, and <0.25 nA leakage at 85 °C.
Technical Context
The DG611AEN-T1-E4 implements four independent, bidirectional analog switches with complementary logic control: logic low enables conduction (NC), logic high disables (open). All switches operate symmetrically with matched on-resistance flatness (≤40 Ω) and exhibit minimal signal distortion (0.01% THD).
It supports dual-supply (±2.7 V to ±5 V) and single-supply (2.7 V to 12 V) operation, with guaranteed 2 V logic-high threshold at ±5 V and 1.4 V at +3 V. Internal ESD protection and rail-to-rail switching enable direct interfacing with ADCs, DACs, and op-amp signal chains without level shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) - all four channels conduct when control input is logic low |
| RON Max | 115 Ω at ±5 V - ensures minimal gain error and voltage drop in precision sensor/ADC front-ends |
| Charge Injection | 1 pC typical - reduces settling error and pedestal distortion in sample-and-hold and data acquisition systems |
| 3 dB Bandwidth | 720 MHz - supports high-speed video, RF sampling, and wideband communication signal paths |
| Off Isolation | -62 dB at 10 MHz - prevents crosstalk between inactive channels in multi-channel instrumentation |
| Leakage Current | <0.25 nA at 85 °C - maintains accuracy in high-impedance, low-current measurement circuits |
| Supply Range | ±2.7 V to ±5 V dual or +2.7 V to +12 V single - compatible with legacy ±5 V and modern low-voltage 3.3 V systems |
Pinout & Package
Package: 16-pin miniQFN (1.8 mm × 2.6 mm), 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; logic low = switch ON (NC path closed); 1.4 V threshold at +3 V supply |
| S1–S4 | Source terminals | Analog inputs/outputs; bidirectional, rail-to-rail capable; connect to signal sources or sensors |
| D1–D4 | Drain terminals | Analog outputs/inputs; matched to Sx pins; used for multiplexed output to ADC or amplifier |
| V+ | Positive supply | Accepts +2.7 V to +12 V (single) or +5 V (dual); powers internal switch driver and logic |
| V− | Negative supply | Accepts -2.7 V to -5 V (dual only); enables true bipolar signal handling down to -5 V |
| GND | Ground reference | Logic ground and substrate reference; must be low-impedance for noise-sensitive analog routing |
| NC | No-connect terminal | Internally unconnected; must remain floating or tied to GND per layout guidelines - no signal routing |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports full-range signal swing from V− to V+ without clipping - eliminates need for external biasing in ±5 V systems |
| Low 2 pF CS(off) | Minimizes capacitive loading on driving source - preserves bandwidth and stability in high-Z transducer interfaces |
| 720 MHz 3 dB bandwidth | Enables use in >100 MSPS data acquisition and video signal routing without attenuation or phase shift |
| 62 dB off-isolation @ 10 MHz | Prevents signal bleed-through between inactive channels - critical for multi-sensor simultaneous sampling |
| 90 dB crosstalk @ 10 MHz | Ensures channel independence in dense PCB layouts - avoids interference in mixed-signal test fixtures |
Applications
| Precision Instrumentation | Automated Test Equipment (ATE) |
|---|---|
|

Use Scenario: Simultaneous sampling of four analog channels into a quad ADC, with per-channel signal conditioning path selection. IC Role / Device Role / Timing Role: Independent SPST switches isolate unused signal paths to reduce noise coupling and maintain SNR. Use Value: -62 dB off-isolation and -90 dB crosstalk ensure channel-to-channel isolation meets 16-bit+ effective resolution requirements. |
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 RON (180 Ω max), lower bandwidth (300 MHz), same 16-pin SOIC package | Less suitable for >10 MSPS sampling; better for cost-sensitive industrial controls with relaxed speed specs | Select when board space allows SOIC and bandwidth ≤300 MHz suffices |
| ADG1411BRUZ | Lower RON (1.8 Ω typ.), higher supply voltage (±15 V), 16-pin TSSOP, higher price | Preferred for ultra-low-distortion audio or high-voltage industrial DAQ where RON matching is critical | Select when sub-2 Ω RON and ±15 V operation outweigh miniQFN size and cost constraints |
Compared with MAX4611ESE+ and ADG1411BRUZ, DG611AEN-T1-E4 uniquely balances ultra-low charge injection (1 pC), 720 MHz bandwidth, and compact miniQFN packaging - making it optimal for space-constrained, high-fidelity ATE and medical front-ends where transient-induced error must be minimized.

Is the miniQFN package of DG611AEN-T1-E4 leadless and RoHS-compliant?
Yes, DG611AEN-T1-E4 uses a 16-pin miniQFN package (1.8 mm × 2.6 mm) with exposed thermal pad, is leadless, and complies with RoHS Directive 2002/95/EC and halogen-free standards per IEC 61249-2-21.
How does DG611AEN-T1-E4 differ from DG612AEN-T1-E4 and DG613AEN-T1-E4?
DG611AEN-T1-E4 has all four switches normally closed (NC); DG612AEN-T1-E4 is normally open (NO); DG613AEN-T1-E4 combines two NC and two NO switches. Pinout and electrical specs are identical - only logic polarity and default state differ.
What is the typical charge injection value for DG611AEN-T1-E4, and why does it matter?
DG611AEN-T1-E4 delivers 1 pC typical charge injection. This low value minimizes voltage glitches on sampled nodes - essential for accurate settling in sample-and-hold circuits and high-resolution data acquisition where even sub-mV errors degrade ENOB.
