Product details
Overview
DG413LDQ-T1 from Vishay Siliconix is a precision monolithic quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, designed for high-speed, low-error signal routing in ±15 V dual-supply or 12 V single-supply systems. It delivers 25 Ω on-resistance, 68 ns turn-on time, and ±0.1 nA off-leakage at full temperature range, enabling use in precision data acquisition front-ends.
For engineers reviewing the DG413LDQ-T1 datasheet, DG413LDQ-T1 pinout, DG413LDQ-T1 application, or DG413LDQ-T1 equivalent, key selection criteria include break-before-make timing (20 ns), charge injection (22 pC), dual-supply compatibility, RoHS-compliant QFN-16 packaging, and guaranteed performance across –40 °C to +85 °C.
Technical Context
The DG413LDQ-T1 implements four independent CMOS analog switches fabricated on Vishay's high-voltage silicon gate process with epitaxial latchup protection. Its internal architecture supports bidirectional conduction when on and blocks analog signals up to supply rails when off.
Control logic follows a complementary truth table: logic low disables SW1/SW4 and enables SW2/SW3; logic high reverses state. Break-before-make operation is intrinsic to SW2/SW3 pairs, with 20 ns delay confirmed under ±15 V dual-supply conditions and RL = 300 Ω/CL = 35 pF loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±15 V dual or 12 V single - supports rail-to-rail analog signal switching without clipping |
| On-Resistance (RDS(on)) | 25 Ω typical at ±15 V - ensures minimal gain error and THD degradation in precision amplifier paths |
| Turn-On Time (tON) | 68 ns max at ±15 V - enables sampling rates up to ~10 MHz in multiplexed ADC interfaces |
| Off-Leakage Current | ±0.1 nA max at full temp - preserves DC accuracy in high-impedance sensor front-ends |
| Charge Injection | 22 pC typical - limits voltage glitch amplitude to <1 mV in 12-bit+ sample-hold circuits |
| Break-Before-Make Delay | 20 ns - prevents momentary shorting between signal paths during channel switching |
| Logic Compatibility | TTL/CMOS with VL = 5 V - allows direct interfacing to microcontrollers and FPGAs without level shifters |
Pinout & Package
Package: 16-pin QFN (4 mm × 4 mm, Variation 1), exposed thermal pad, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 15, 16 | IN1–IN4 | Digital control inputs - active-high logic for SW1/SW4; active-low for SW2/SW3 per truth table |
| 3, 4, 13, 14 | D1–D4 | Drain terminals - analog outputs of NO/NC switches; bidirectional signal path |
| 5, 6, 11, 12 | S1–S4 | Source terminals - analog inputs tied to common signal source or sensor |
| 7 | V− | Negative supply rail - required for dual-supply operation; connects to –15 V or GND in unipolar mode |
| 8 | V+ | Positive supply rail - accepts up to +44 V; sets upper analog signal limit |
| 9 | GND | Analog/digital ground reference - must be low-impedance return for leakage-sensitive applications |
| 10 | VL | Logic supply - powers internal level shifter; fixed at 5 V regardless of analog supply |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 20 ns delay between SW2/SW3 transitions prevents signal shorting in relay-replacement designs |
| Ultra-low power dissipation | 0.35 µW typical - enables always-on operation in battery-powered DAQ systems for >10-year runtime |
| High-voltage tolerance | 44 V max V+–V− rating - supports industrial ±20 V signal conditioning without external clamping |
| Latchup immunity | Epitaxial isolation layer - eliminates risk of destructive latchup under overvoltage or ESD stress |
| Low charge injection | 22 pC typical - reduces hold-mode settling error in precision sample-and-hold amplifiers |

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 |
|---|---|---|---|
| MAX4613ESE+ | Higher RDS(on) (45 Ω), slower tON (120 ns), no break-before-make guarantee | Lower cost; suitable where speed and glitch immunity are non-critical | Prefer DG413LDQ-T1 when sub-100 ns switching and deterministic break-before-make are required |
| ADG1413BRUZ | Lower RDS(on) (12 Ω), higher supply rating (±20 V), but 3.3 V logic-only interface | Requires level-shifting for 5 V MCU control; better for ultra-low distortion audio paths | Choose DG413LDQ-T1 for native 5 V logic compatibility and proven robustness in industrial environments |
Compared with MAX4613ESE+ and ADG1413BRUZ, the DG413LDQ-T1 uniquely balances 68 ns speed, 20 ns break-before-make, 5 V logic support, and 0.35 µW power in a compact QFN-making it optimal for space-constrained, battery-operated precision instrumentation requiring deterministic switching behavior.

FAQ
What is the maximum analog signal voltage supported by the DG413LDQ-T1?
The DG413LDQ-T1 supports analog signals from V− to V+, with absolute maximum V+–V− rating of 44 V. Under ±15 V dual-supply operation, it handles ±15 V signals; under 12 V single-supply (V− = GND), it supports 0 V to 12 V signals. Exceeding these ranges triggers internal diode clamping, requiring external current limiting per datasheet Note a.
Does the DG413LDQ-T1 require separate logic and analog supplies?
Yes - the DG413LDQ-T1 requires three supplies: V+ and V− for analog switching, plus VL = 5 V for digital logic. VL is internally decoupled and must remain at 5 V regardless of analog supply configuration. This separation ensures TTL/CMOS-compatible input thresholds while maintaining full analog signal swing.
How does the break-before-make function operate in the DG413LDQ-T1?
The DG413LDQ-T1 implements break-before-make exclusively between SW2 and SW3 (pins IN2/IN3 controlled), with a guaranteed 20 ns minimum delay measured at ±15 V, RL = 300 Ω, CL = 35 pF. SW1 and SW4 operate independently with no inter-channel timing constraint. This architecture prevents signal shorting only in the NC/NO pair, not across all four switches.
Can the DG413LDQ-T1 be used with a single 5 V supply?
No - the DG413LDQ-T1 cannot operate with only a 5 V supply. Its analog signal range requires either dual supplies (e.g., ±15 V) or a unipolar supply ≥12 V (V+ = 12 V, V− = GND). The 5 V VL supply powers only the logic interface; analog switching capability depends on sufficient V+–V− differential to support the desired signal swing.
What is the thermal pad connection requirement for the DG413LDQ-T1 QFN package?
Per Vishay's QFN-16 package outline (Document 71921), the exposed thermal pad of the DG413LDQ-T1 must be soldered to a solid copper thermal plane on the PCB for reliable heat dissipation and mechanical stability. The pad is electrically connected to V− internally; therefore, it must be tied to the V− net, not GND or floating, to avoid violating absolute maximum ratings.
