Product details
Overview
DG333ADW-T1-E3 from Vishay Siliconix is a precision quad SPDT analog switch IC designed for high-accuracy signal routing in instrumentation and test systems. It features 25 Ω typical on-resistance, 175 ns max turn-on time, ±22 V dual-supply operation, and 0.25 nA max off-leakage at 85 °C - enabling low-error switching of rail-to-rail analog signals up to ±22 V in battery-powered or high-fidelity audio paths.
For engineers reviewing the DG333ADW-T1-E3 datasheet, DG333ADW-T1-E3 pinout, DG333ADW-T1-E3 application, or DG333ADW-T1-E3 equivalent, key selection criteria include verified break-before-make timing, channel-to-channel on-resistance matching (<2 Ω), flat RDS(on) over signal range (Δ <3 Ω), and micro-power compatibility with portable systems requiring <1 μA supply current.
Technical Context
The DG333ADW-T1-E3 integrates four independently controlled SPDT switches fabricated in Vishay's HVSG-2 CMOS process, supporting both bipolar (±4 V to ±22 V) and unipolar (5 V to 40 V) supply configurations. Each switch conducts bidirectionally with rail-to-rail analog signal handling and includes epitaxial latchup protection.
Its improved charge injection compensation design limits transients to ≤10 pC, while TTL/CMOS-compatible digital inputs (VINH ≥2.4 V, VINL ≤0.8 V) ensure direct interfacing with microcontrollers and FPGAs without level-shifting. Break-before-make delay is guaranteed ≥5 ns to prevent signal shorting during state transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±4 V to ±22 V (dual) or +5 V to +40 V (single) - supports wide-range industrial and test equipment rails |
| On-Resistance | 25 Ω typ. at ±15 V - ensures minimal signal attenuation and gain error in precision measurement paths |
| RDS(on) Match | <2 Ω max between channels - critical for matched gain/phase in multi-channel instrumentation |
| Charge Injection | 10 pC max - reduces voltage glitch on switched capacitors in filter and sampling circuits |
| Off-Leakage Current | 0.25 nA max at 85 °C - preserves accuracy in high-impedance sensor front-ends and integrators |
| Switching Time | tON = 175 ns max, tOFF = 145 ns max - enables reliable operation up to ~2 MHz clocked switched-capacitor networks |
| Off Isolation | 72 dB min at 1 MHz - suppresses crosstalk between adjacent channels in dense PCB layouts |
Pinout & Package
Package: 20-pin wide-body SOIC (SO-20W), 7.62 mm × 15.4 mm body, 1.27 mm pitch, RoHS-compliant matte tin lead finish.

|---|---|---|
| 1, 4, 5, 8, 13, 16, 17, 20 | Switch Inputs (IN1–IN4, S1–S4) | Digital control lines for four independent SPDT switches; TTL/CMOS compatible |
| 2, 3, 6, 7, 14, 15, 18, 19 | Switch Outputs (D1–D4, S5–S8) | Analog signal terminals - Dx are normally open, Sx are normally closed per truth table |
| 9, 12 | Power Supplies (V+, V−) | Bipolar rails accepting ±4 V to ±22 V; enable rail-to-rail analog signal swing |
| 10 | GND | Analog/digital reference common - must be low-impedance for leakage and noise control |
| 11 | Not Connected (NC) | No internal connection - must be left floating or tied to GND per layout best practice |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Higher on-resistance (60 Ω typ.), lower supply voltage range (±20 V max), no break-before-make guarantee | Less suitable for precision metrology; acceptable for general-purpose audio routing | Select when cost sensitivity outweighs on-resistance matching and transient performance requirements |
| ADG1434BRUZ | Lower on-resistance (4.7 Ω typ.), higher supply current (220 μA), wider temp range (−40°C to +125°C) | Better for high-temp industrial control; over-specified for battery-powered portables | Choose when ultra-low RDS(on) and extended temperature operation justify higher power and cost |
Compared with MAX4617ESE+ and ADG1434BRUZ, the DG333ADW-T1-E3 delivers optimal balance of precision (25 Ω RDS(on), <2 Ω match), ultra-low power (<1 μA), and proven break-before-make behavior - making it preferred for portable test gear and high-fidelity audio where leakage, glitch energy, and supply budget are tightly constrained.

FAQ
What is the maximum analog signal voltage the DG333ADW-T1-E3 can switch?
The DG333ADW-T1-E3 supports analog signals from V− to V+, with absolute maximum ratings of ±22 V on V+ and V−. Signals exceeding these rails are clamped by internal diodes - so the practical maximum undistorted analog range is ±22 V when powered within specification. This makes DG333ADW-T1-E3 suitable for high-voltage industrial sensor interfaces and legacy test equipment rails.
Does the DG333ADW-T1-E3 require external pull-up or pull-down resistors on its digital control inputs?
No, the DG333ADW-T1-E3 has TTL- and CMOS-compatible digital inputs with guaranteed thresholds (VINH ≥2.4 V, VINL ≤0.8 V) and input currents ≤±1 μA across temperature. Direct connection to FPGA GPIO or microcontroller outputs is supported without external biasing - simplifying layout and reducing BOM count for the DG333ADW-T1-E3 in compact designs.
Is Pin 15 of the DG333ADW-T1-E3 connected internally?
No - Pin 15 is not connected (NC) on the DG333ADW-T1-E3, consistent with the DG333A variant (as opposed to the DG333AL, which uses Pin 15 for VL). The datasheet explicitly states "Pin 15 is not connected on the DG333A", and DG333ADW-T1-E3 is the SOIC-packaged DG333A variant. It must remain unconnected or tied to GND per layout guidelines.
Can the DG333ADW-T1-E3 operate from a single 12 V supply?
Yes - the DG333ADW-T1-E3 supports unipolar operation from +5 V to +40 V. At V+ = 12 V and V− = 0 V, it delivers 35 Ω typical on-resistance and maintains 0.25 nA max off-leakage, enabling use in 12 V industrial controllers and automotive auxiliary systems. Performance metrics differ slightly from dual-supply mode, as confirmed in the Unipolar Supplies section of the DG333ADW-T1-E3 datasheet.
How does the DG333ADW-T1-E3 handle charge injection during switching?
The DG333ADW-T1-E3 employs an improved charge injection compensation design that limits injected charge to 10 pC max (tested at CL = 10 nF). This minimizes voltage glitches on high-impedance nodes - critical in switched-capacitor filters and sample-and-hold circuits. Measured charge injection remains stable across temperature and supply voltage, ensuring predictable settling behavior for the DG333ADW-T1-E3 in precision timing applications.
