Product details
Overview
DG2732DN-T1-E4 from Vishay Siliconix is a low-voltage, dual SPDT analog switch with 0.4 Ω typical on-resistance at 3.6 V, 50 ns turn-on time, and operation from 1.6 V to 4.3 V single supply. It features reverse control logic, break-before-make switching, and is optimized for audio routing and battery-powered portable systems.
For engineers reviewing the DG2732DN-T1-E4 datasheet, DG2732DN-T1-E4 pinout, DG2732DN-T1-E4 application, or DG2732DN-T1-E4 equivalent, key selection criteria include on-resistance matching (±0.06 Ω), ±250 mA continuous channel current, latch-up immunity >300 mA, and DFN-10 package compatibility with 1.6-V logic interfaces.
Technical Context
The DG2732DN-T1-E4 implements two independent SPDT switches in a monolithic CMOS process, each with separate digital control inputs operating under reverse logic (low = ON). Its sub-micron low-voltage architecture ensures rail-to-rail analog signal conduction and guaranteed break-before-make timing of ≤10 ns across temperature.
Designed for direct interface with 1.6-V logic, the device supports bidirectional analog signal routing up to the supply rail (V+), with off-isolation of –75 dB at 100 kHz and crosstalk < –75 dB - critical for high-fidelity audio path separation in compact handheld devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (rON) | 0.4 Ω typ @ 3.6 V - enables minimal voltage drop and signal distortion in low-voltage audio paths |
| Supply range | 1.6 V to 4.3 V - supports direct one-cell Li-ion (2.7–4.2 V) and regulated 1.8/3.3 V rails |
| Turn-on time (tON) | 50 ns @ 4.3 V - ensures fast channel switching for dynamic audio routing without audible artifacts |
| Break-before-make time | ≤10 ns - prevents momentary shorting between NC and NO paths during state transitions |
| Latch-up immunity | >300 mA per JESD78 - guarantees robustness against transient overcurrent events in portable systems |
| Logic compatibility | 1.6-V input threshold - interoperates directly with low-power DSPs and MCUs without level-shifting |
| Channel leakage (off) | ±20 nA max @ 4.3 V - preserves signal integrity in high-impedance sensor/audio circuits |
Pinout & Package
The DG2732DN-T1-E4 is housed in a lead (Pb)-free 10-pin DFN package (2.5 mm × 2.5 mm × 0.55 mm) with nickel-palladium-gold terminations, rated MSL 1 and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 6, 7, 8, 9 | Analog I/O (COM1, NO1, NC1, COM2, NO2, NC2, IN1, IN2) | Two fully independent SPDT switch channels; COM pins are bidirectional analog ports; IN1/IN2 accept reverse-logic digital control |
| 5, 10 | GND | Power and signal reference ground; both pins must be connected for thermal and EMI performance |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance matching | ΔrON ≤ 0.06 Ω - ensures balanced signal gain across dual channels in stereo audio routing |
| Rail-to-rail analog operation | VCOM/VNO/VNC = 0 to V+ - supports full-supply-swing signals without clipping in 1.8 V systems |
| Charge injection | 9 pC max - minimizes voltage glitch on high-impedance nodes during switching (e.g., codec inputs) |
| Off-isolation | –75 dB @ 100 kHz - suppresses crosstalk between active and inactive audio paths |
| ESD protection | HBM ≥ 2 kV - provides system-level robustness against handling and interface transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4682EUB+ | Higher rON (0.8 Ω typ @ 3 V), 10-pin µMAX package, no latch-up rating specified | Less suitable for Li-ion direct power due to higher on-resistance and narrower 2.7–5.5 V supply range | Select when footprint compatibility with µMAX layout is required and 0.8 Ω rON is acceptable |
| ADG732BRUZ | 32-channel, serial SPI interface, 0.8 Ω rON, TSSOP-48 package | Designed for high-channel-count, programmable routing - not pin-compatible or functionally equivalent for dual SPDT use | Select only for systems requiring software-configurable multi-channel switching with SPI control |
Compared with MAX4682EUB+ and ADG732BRUZ, the DG2732DN-T1-E4 delivers lower on-resistance, guaranteed latch-up immunity, and native 1.6-V logic support - making it optimal for space-constrained, battery-critical audio and sensor routing where analog signal integrity and supply flexibility are primary design constraints.

FAQ
What is the maximum continuous current rating per channel for DG2732DN-T1-E4?
The DG2732DN-T1-E4 supports ±250 mA continuous current through each NO/NC/COM terminal, verified per absolute maximum ratings in the Vishay datasheet (Document 73484). This rating applies across the full operating temperature range (–40°C to +85°C) and ensures reliable conduction in audio driver and sensor signal paths without thermal derating below 70°C.
Does DG2732DN-T1-E4 support true bidirectional analog signal switching?
Yes, the DG2732DN-T1-E4 supports fully bidirectional analog signal conduction - signals pass equally well from COM to NO/NC or from NO/NC to COM when the switch is on. This is confirmed by its rail-to-rail analog voltage range (0 to V+) and symmetric on-resistance specification, making DG2732DN-T1-E4 suitable for AC-coupled audio and sensor interfaces where signal polarity varies.
What logic polarity does DG2732DN-T1-E4 use for its control inputs?
The DG2732DN-T1-E4 uses reverse control logic: a logic low (≤0.5 V) on IN1 or IN2 turns the corresponding SPDT switch ON (connects COM to NO), while a logic high (≥1.4 V at 1.8 V supply) turns it OFF. This behavior is explicitly defined in the truth table and functional description of DG2732DN-T1-E4 in Vishay's datasheet revision A.
Is DG2732DN-T1-E4 pin-compatible with DG2731DN-T1-E4 or DG2733DN-T1-E4?
No, DG2732DN-T1-E4 is not pin-compatible with DG2731DN-T1-E4 or DG2733DN-T1-E4. While all three share the same DFN-10 package outline, DG2731DN-T1-E4 has identical reverse-logic control but different pin assignment for IN1/IN2, and DG2733DN-T1-E4 substitutes EN for one control input - altering the pin function map. Layout reuse requires verification against each part's specific pin configuration diagram.
What is the thermal resistance (θJA) of DG2732DN-T1-E4 in its DFN-10 package?
The DG2732DN-T1-E4 DFN-10 package has a junction-to-ambient thermal resistance (θJA) of 105°C/W, derived from its 1191 mW maximum power dissipation rating at 25°C ambient and 70°C derating inflection point. This value assumes standard JEDEC 2-layer board conditions and confirms suitability for thermally constrained portable PCB layouts.
