Product details
Overview
DG2612DX-T1-E3 from Vishay Siliconix is a low-voltage, low-RON, SPDT analog audio switch with negative signal swing capability and break-before-make switching. It operates from 1.8 V to 5.5 V, delivers 1.0 Ω on-resistance at 2.7 V, and is housed in an SC-89 (SOT-666) package - ideal for portable audio routing in space-constrained battery-powered devices.
For engineers reviewing the DG2612DX-T1-E3 datasheet, DG2612DX-T1-E3 pinout, DG2612DX-T1-E3 application, or DG2612DX-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing, shunt-switch noise suppression, DC-coupled signal path compatibility, and -40 °C to +85 °C industrial temperature operation.
Technical Context
The DG2612DX-T1-E3 implements a monolithic CMOS SPDT switch architecture with integrated shunt switch for transient noise reduction. Its analog signal range extends from (V+ − 5.5) V to V+ V, enabling true negative-swing audio handling down to −1 V at COM when V+ = 2.7 V.
It features logic-controlled digital inputs compatible across supply voltages (VINH = 1.0 V min at V+ = 1.8 V; 2.0 V min at V+ = 5.5 V), with <60 ns turn-on time and <37 ns turn-off time under 50 Ω/35 pF load conditions - optimized for high-fidelity portable audio signal routing without coupling capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct integration with Li-ion battery rails and 3.3 V/5 V logic domains |
| On-Resistance (RON) | 1.0 Ω typical at V+ = 2.7 V, VCOM = 0 V - minimizes insertion loss and THD in audio paths |
| Break-Before-Make Time | 4–16 ns - prevents momentary shorting between NC and NO during state transition |
| Off-Isolation (OIRR) | −61 dB at 100 kHz - suppresses crosstalk between inactive channels in multi-source audio systems |
| Charge Injection | Not specified for DG2612 - unlike DG2613 (2.4 pC), DG2612 lacks documented QINJ data in spec table |
| Shunt Switch Resistance | 150–300 Ω - provides low-impedance discharge path to reduce pop/click artifacts during switching |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial-grade portable electronics deployment |
Pinout & Package
Package: SC-89 (SOT-666), 6-pin surface-mount, 1.66 mm × 1.65 mm × 0.56 mm body, lead (Pb)-free matte tin terminations per -E3 suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Active-high logic signal controlling switch state; compatible with 1.8 V–5.5 V CMOS logic levels |
| 2 (V+) | Positive supply rail | Primary analog and digital power source; supports 1.8–5.5 V operation with internal level-shifting |
| 3 (GND) | Analog/digital ground reference | Common return for analog signal path and logic interface; must be low-impedance for noise immunity |
| 4 (NC) | Normally closed analog terminal | Connected to COM when IN = 0 V; rated for ±150 mA continuous current |
| 5 (COM) | Common analog port | Signal hub connecting to either NC or NO; supports bidirectional analog signals including negative swing |
| 6 (NO) | Normally open analog terminal | Connected to COM when IN = V+; shares same voltage and current ratings as NC |
Key Features
| Feature | Design Value |
|---|---|
| Negative signal swing capability | Supports analog signals down to (V+ − 5.5) V - enables true DC-coupled audio paths without blocking capacitors |
| Guaranteed break-before-make | 4–16 ns minimum dead time prevents NC–NO shorting - critical for glitch-free audio channel switching |
| Integrated shunt switch | 150–300 Ω path discharges COM node during transition - reduces audible pop/click in headphone and speaker outputs |
| Low 1.0 Ω RON at 2.7 V | Minimizes gain error and frequency-dependent attenuation in line-level and headphone drive applications |
| SC-89 (SOT-666) footprint | 1.66 mm × 1.65 mm body with 0.5 mm pitch - saves >50 % board area vs. SOIC-8 while maintaining 6-terminal routing flexibility |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TS5A23157DBVR | RON = 0.9 Ω at 3.3 V; no negative swing (VIN ≥ 0 V); smaller 5-pin SC70 package | Limited to single-ended, ground-referenced audio paths; unsuitable for true bipolar signal routing | Select when only positive-only signal switching is required and board space is more constrained than analog performance. |
| Analog Devices ADG849YRMZ-REEL7 | RON = 0.5 Ω at 3 V; supports −0.3 V to V+ + 0.3 V analog range; 8-pin MSOP package | Higher precision but larger footprint; requires additional PCB area and layout complexity | Choose for ultra-low RON and extended analog range where SC-89 size is not mandatory. |
Compared with TS5A23157DBVR and ADG849YRMZ-REEL7, the DG2612DX-T1-E3 uniquely balances sub-1.5 Ω RON, guaranteed break-before-make, negative swing capability, and minimal SC-89 footprint - making it optimal for compact, high-integrity portable audio routing where DC coupling and glitch-free switching are design-critical.

FAQ
What is the maximum analog signal voltage range supported by the DG2612DX-T1-E3?
The DG2612DX-T1-E3 supports analog signals from (V+ − 5.5) V to V+ V. For example, at V+ = 2.7 V, the valid range is −2.8 V to +2.7 V - enabling true negative-swing audio handling without external biasing. This specification is confirmed in the Absolute Maximum Ratings table and functional description of the DG2612DX-T1-E3 datasheet.
Does the DG2612DX-T1-E3 provide guaranteed break-before-make timing?
Yes, the DG2612DX-T1-E3 guarantees break-before-make operation with a minimum interval of 4 ns and maximum of 16 ns, as specified in the Dynamic Characteristics table. This timing prevents momentary shorting between NC and NO terminals during switching - a critical feature for glitch-free audio path selection in the DG2612DX-T1-E3.
What is the on-resistance (RON) of the DG2612DX-T1-E3 at 3.3 V supply?
The DG2612DX-T1-E3 has a typical on-resistance of 1.0 Ω at V+ = 2.7 V. At 3.3 V, the datasheet does not list a specific RON value, but the RON vs. V+ curve shows monotonic decrease - implying ~0.9 Ω typical. However, only the 2.7 V value is guaranteed and tested; design margins should use the 1.4 Ω max at full temperature range for the DG2612DX-T1-E3.
Is the DG2612DX-T1-E3 pin-compatible with the DG2613DX-T1-E3?
No, the DG2612DX-T1-E3 and DG2613DX-T1-E3 share identical pinout and package (SC-89), but differ electrically: DG2613 specifies charge injection (2.4 pC) and higher off-isolation (−67 dB), while DG2612 does not. They are functionally interchangeable only if those parameters are not design-critical - the DG2612DX-T1-E3 is not a drop-in replacement for DG2613DX-T1-E3 in high-isolation or low-glitch applications.
What package type and termination does the DG2612DX-T1-E3 use?
The DG2612DX-T1-E3 uses the SC-89 (SOT-666) package - a 6-pin, 1.66 mm × 1.65 mm surface-mount outline - with 100 % matte tin, lead (Pb)-free terminations, as indicated by the "-E3" suffix per Vishay's standard designation system for the DG2612DX-T1-E3.
