Product details
Overview
DG412LDQ-T1-E3 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch with break-before-make switching action, 17 Ω on-resistance (RDS(on)), 19 ns turn-on time (tON), and ±3 V to ±6 V dual-supply or 2.7 V to 12 V single-supply operation - used in precision audio/video signal routing and battery-powered data acquisition systems.
For engineers reviewing the DG412LDQ-T1-E3 datasheet, DG412LDQ-T1-E3 pinout, DG412LDQ-T1-E3 application, or DG412LDQ-T1-E3 equivalent, key selection criteria include guaranteed RDS(on) flatness over signal range, sub-15 ns tOFF, 0.25 nA max leakage at 25 °C, 2000 V ESD protection, and compatibility with TTL/CMOS logic levels.
Technical Context
The DG412LDQ-T1-E3 implements four independent normally-open analog switches with complementary control logic versus DG411L (i.e., logic "0" = ON, logic "1" = OFF), enabling precise sequencing in multiplexed signal paths. Its BiCMOS process ensures rail-to-rail analog signal handling across supply configurations.
It features integrated level-shifting circuitry referenced to VL pin for robust digital interface operation, supports break-before-make timing only in DG413L variant (not applicable), and maintains <5 Ω RDS(on) variation over full analog input range - critical for low-distortion instrumentation-grade switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 17 Ω typical at V+ = 12 V, ensuring minimal signal attenuation and voltage drop in precision analog paths |
| tON | 19 ns typical (RL = 300 Ω, CL = 35 pF), enabling high-speed channel selection in real-time data acquisition |
| tOFF | 12 ns typical, supporting fast signal isolation and reducing crosstalk in time-critical routing |
| Leakage Current | 0.25 nA max at 25 °C, preserving signal integrity in high-impedance sensor interfaces |
| Analog Signal Range | 0 to 12 V (single supply) or ±5 V (dual supply), covering industrial and audio signal levels |
| ESD Protection | 2000 V HBM, allowing safe handling and integration into unshielded portable equipment |
| Supply Range | 2.7–12 V single or ±3–±6 V dual, supporting wide-battery and mixed-rail system designs |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MO-153, MS-012), 4.4 mm × 5.0 mm body, 0.65 mm pitch, RoHS-compliant lead finish (Pb-free with NiPdAu termination).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-low logic: logic "0" ≤ 0.8 V enables corresponding switch; TTL/CMOS compatible |
| S1–S4 | Switch source terminals | Analog inputs for each SPST channel; connected internally to D when enabled |
| D1–D4 | Switch drain terminals | Analog outputs; routed to S only when respective INx = 0 |
| V+ | Positive analog supply | Bias for analog path; sets upper rail of signal range (e.g., +12 V or +5 V) |
| V− | Negative analog supply | Required for dual-supply operation; sets lower rail (e.g., −5 V); tied to GND for single supply |
| GND | Analog ground reference | Return path for analog signals and substrate bias; separate from digital ground in mixed-signal layouts |
| VL | Logic supply reference | Defines logic threshold (0.8 V / 2.4 V) independently of V+/V−; typically tied to 5 V or 3.3 V |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports full 0–12 V or ±5 V signal swing without clipping, essential for undistorted audio/video routing |
| Low and flat RDS(on) | 17 Ω typical with <5 Ω variation across signal range, minimizing gain error and THD in precision measurement |
| Ultra-low leakage | 0.25 nA max off-state current preserves DC accuracy in high-Z sensor front-ends and integrator circuits |
| Fast, matched switching | 19 ns tON/12 ns tOFF with tight matching ensures synchronized channel switching in multi-channel DAQ systems |
| TTL/CMOS logic compatibility | Accepts standard 0.8 V / 2.4 V thresholds with µA-level input current, simplifying interface to microcontrollers and FPGAs |

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) (45 Ω typ), slower tON (40 ns), but offers fault protection and higher supply tolerance (up to ±20 V) | Suitable for industrial I/O modules requiring overvoltage survivability, not precision low-distortion routing | Select MAX4612ESE+ only when fault protection outweighs on-resistance and speed requirements |
| ADG1412BRUZ | Lower RDS(on) (1.3 Ω typ), faster switching (12 ns), but requires ≥4.5 V supply and lacks 2.7 V operation | Ideal for high-performance automated test equipment where supply headroom permits, not battery-constrained devices | Choose ADG1412BRUZ when ultra-low distortion and speed are mandatory and 5 V rail is available |
Compared with DG412LDQ-T1-E3, MAX4612ESE+ trades speed and on-resistance for ruggedness, while ADG1412BRUZ delivers superior analog performance at the cost of low-voltage flexibility - making DG412LDQ-T1-E3 optimal for balanced precision, speed, and 2.7 V operability.

FAQ
What is the maximum analog signal voltage range supported by DG412LDQ-T1-E3?
DG412LDQ-T1-E3 supports an analog signal range of 0 V to 12 V with single supply (V− = GND), or ±5 V with dual supply (V+ = +5 V, V− = −5 V). Operation outside these ranges risks clamping by internal protection diodes and must be avoided per Absolute Maximum Ratings.
Does DG412LDQ-T1-E3 require a separate logic supply voltage?
Yes - DG412LDQ-T1-E3 uses the VL pin to set logic thresholds independently of analog supplies. VL must be connected to a stable 3.3 V or 5 V source to ensure correct interpretation of logic "0" (≤ 0.8 V) and logic "1" (≥ 2.4 V) levels across temperature and supply variations.
Is DG412LDQ-T1-E3 pin-compatible with the legacy DG412 device?
Yes - DG412LDQ-T1-E3 is explicitly designed as a low-voltage pin-for-pin compatible upgrade to the industry-standard DG412, offering improved RDS(on), faster switching, and enhanced ESD protection while retaining identical pinout and functional behavior in 16-pin SOIC and TSSOP packages.
What is the guaranteed maximum on-resistance for DG412LDQ-T1-E3 over temperature?
Per datasheet specifications, DG412LDQ-T1-E3 guarantees RDS(on) ≤ 45 Ω over the full −40 °C to +85 °C operating range at V+ = 10.8 V, V− = 0 V, and IS = 10 mA - verified across production lots and not just typical values.
Can DG412LDQ-T1-E3 operate from a single 3.3 V supply?
Yes - DG412LDQ-T1-E3 operates down to 2.7 V single supply. At 3.3 V, it delivers RDS(on) ≤ 80 Ω (max), tON ≤ 110 ns, and maintains 0.25 nA leakage, making it suitable for modern low-power embedded systems powered by 3.3 V LDOs or buck converters.
