Product details
Overview
DG2732DQ-T1-E3 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 1.6 V to 4.3 V single-supply operation. It features reverse control logic, break-before-make switching, and ±250 mA continuous current handling-designed for audio routing in portable battery-powered systems.
For engineers reviewing the DG2732DQ-T1-E3 datasheet, DG2732DQ-T1-E3 pinout, DG2732DQ-T1-E3 application, or DG2732DQ-T1-E3 equivalent, key selection criteria include on-resistance matching (±0.06 Ω), 10-pin MSOP package compatibility, TTL/1.6-V logic interface, and latch-up immunity exceeding 300 mA per JESD78.
Technical Context
The DG2732DQ-T1-E3 implements two independent SPDT switches in a monolithic CMOS process, each with separate IN1/IN2 control inputs using reverse logic (low = ON). Its sub-micron low-voltage architecture enables rail-to-rail analog signal conduction and guarantees break-before-make timing of ≤10 ns across temperature.
It operates without external biasing, supports bidirectional analog signals up to the supply rail (V+), and maintains <10 pA off-leakage at 85°C. The device draws only 1.0 µA quiescent supply current and tolerates analog voltages beyond V+ via internal clamping diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 0.4 Ω typ @ 3.6 V - ensures minimal signal attenuation in audio paths |
| Supply range | 1.6 V to 4.3 V - supports direct one-cell Li-ion (2.7–4.2 V) and 1.8 V/3.3 V logic domains |
| Turn-on time | 50 ns @ 4.3 V - enables fast channel switching in headset detection circuits |
| Off-isolation | –75 dB @ 100 kHz - suppresses crosstalk between adjacent audio channels |
| Latch-up immunity | >300 mA per JESD78 - prevents destructive failure during ESD or overcurrent events |
| Logic compatibility | 1.6 V input threshold - interfaces directly with low-voltage DSPs and MCUs without level shifters |
| Charge injection | 9 pC - limits glitch amplitude in precision sensor multiplexing applications |
Pinout & Package
The DG2732DQ-T1-E3 is housed in a 10-pin MSOP package (3.0 mm × 3.0 mm × 1.0 mm height) with matte tin terminations, RoHS-compliant and MSL-1 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 6, 7, 8, 9 | NO1, COM1, NC1, IN1, IN2, NC2, COM2, NO2 | Two independent SPDT switch terminals with dedicated control pins; pin 1 = NO1, pin 2 = COM1, pin 3 = NC1, pin 4 = IN1, pin 6 = IN2, pin 7 = NC2, pin 8 = COM2, pin 9 = NO2 |
| 5, 10 | V+, GND | Single power supply and ground reference; no separate analog/digital ground required |
Key Features
| Feature | Design Value |
|---|---|
| Reverse control logic | IN = low activates switch - simplifies direct connection to open-drain MCU GPIOs |
| Rail-to-rail analog conduction | Signals swing from GND to V+ without clipping - preserves full dynamic range in audio paths |
| Matched on-resistance | ΔrON ≤ 0.06 Ω - minimizes gain error in differential signal routing |
| Low charge injection | 9 pC - reduces voltage step artifacts when switching DC-coupled sensor signals |
| Break-before-make guarantee | ≤10 ns tBBM - prevents momentary shorting between NC/NO paths during transition |

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), 10-pin µMAX package, no latch-up rating specified | Targeted at industrial instrumentation; lacks JESD78-certified latch-up immunity | Select DG2732DQ-T1-E3 for portable designs requiring guaranteed >300 mA latch-up protection and lower on-resistance |
| ADG732BRUZ | 32-channel, serial SPI interface, 4.5 Ω rON, 24-lead TSSOP | Designed for high-channel-count, software-configured routing-not pin-compatible or functionally equivalent | Choose DG2732DQ-T1-E3 for simple, low-latency, dual SPDT switching with minimal board space and zero firmware overhead |
Compared with MAX4682EUB+ and ADG732BRUZ, the DG2732DQ-T1-E3 delivers superior on-resistance (0.4 Ω vs. 0.8 Ω/4.5 Ω), guaranteed break-before-make timing, and JESD78-verified latch-up immunity-making it optimal for space-constrained, battery-sensitive audio and sensor front-end applications where reliability and analog fidelity are critical.

FAQ
What is the maximum supply voltage rating for DG2732DQ-T1-E3?
The DG2732DQ-T1-E3 has an absolute maximum supply voltage (V+) of 5.0 V, but its functional operating range is specified from 1.6 V to 4.3 V. Operation above 4.3 V is not guaranteed per datasheet specifications, and sustained use beyond this may impact reliability or parametric performance. Always refer to the Absolute Maximum Ratings table in the official Vishay document 73484 for derating guidance.
Does DG2732DQ-T1-E3 support bidirectional analog signal switching?
Yes, the DG2732DQ-T1-E3 supports fully bidirectional analog signal conduction when enabled - signals pass equally well from COM to NO/NC or from NO/NC to COM, within the 0 V to V+ analog voltage range. This capability is inherent to its CMOS transmission-gate architecture and is confirmed across all test conditions in the DG2732DQ-T1-E3 datasheet.
What does the "-E3" suffix indicate in DG2732DQ-T1-E3?
The "-E3" suffix in DG2732DQ-T1-E3 denotes a lead (Pb)-free device termination using 100% matte tin plating, compliant with RoHS and JEDEC reflow standards. It identifies the MSOP-10 package variant and confirms MSL-1 moisture sensitivity level - critical for assembly planning and solder profile validation in production environments.
Is DG2732DQ-T1-E3 pin-compatible with DG2731DQ-T1-E3 or DG2733DQ-T1-E3?
No - DG2732DQ-T1-E3 is not pin-compatible with DG2731DQ-T1-E3 or DG2733DQ-T1-E3. While all three share the same 10-pin MSOP package and pinout layout, their control logic differs: DG2731/DG2732 use dual independent reverse-logic inputs, whereas DG2733 replaces one control input with an EN pin. Swapping them requires PCB-level logic redesign.
What is the guaranteed break-before-make time for DG2732DQ-T1-E3?
The DG2732DQ-T1-E3 guarantees a break-before-make time (tBBM) of ≤10 ns across the full operating temperature range (–40°C to +85°C), as verified in the datasheet's SPECIFICATIONS (V+ = 4.3 V) table. This ensures no overlap between NC and NO paths during switching, preventing transient shorts in sensitive analog signal chains.
