Product details
Overview
DG2750DN1-T1-GE4 from Vishay Siliconix is a dual SPDT analog switch optimized for low-voltage audio routing, operating from 1.6 V to 5.5 V single supply with 0.45 Ω typical on-resistance, -98 dB THD+N, and negative-swing audio capability down to (V+) − 5 V - enabling capacitorless headphone and microphone signal paths in portable media players.
For engineers reviewing the DG2750DN1-T1-GE4 datasheet, DG2750DN1-T1-GE4 pinout, DG2750DN1-T1-GE4 application, or DG2750DN1-T1-GE4 equivalent, this device supports high-fidelity analog switching in space-constrained designs where low distortion, latch-up immunity (>600 mA), and 1.4 V logic compatibility are critical selection criteria.
Technical Context
The DG2750DN1-T1-GE4 implements two independent SPDT switches using sub-micron CMOS process, each with break-before-make timing (800–1160 ns) and guaranteed operation across -40 °C to +85 °C. Its analog signal range extends from (V+) − 5 V to V+, eliminating DC-blocking capacitors in bidirectional audio paths.
Control logic accepts 1.4 V high-level inputs when V+ is 2.7–5.5 V, enabling direct interfacing with low-voltage DSPs and ASICs. The device features 36 pF channel-off capacitance and 106 pF channel-on capacitance, supporting 49 MHz bandwidth with -60 dB crosstalk and -54 dB off-isolation at 300 kHz.
Key Specifications

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 |
|---|---|---|---|
| TMUX1574RSVR | Higher 0.75 Ω RON, 1.65–5.5 V supply, no negative-swing capability (requires ≥0 V input) | Not suitable for capacitorless mic bias or headphone output; requires level-shifting for sub-zero signals | Select only if negative-swing operation is unnecessary and higher RON is acceptable |
| ADG822BRMZ-REEL | 0.5 Ω RON, 1.8–5.5 V, 1.65 V logic compatible, but lacks guaranteed (V+) − 5 V analog range | Cannot reliably pass negative audio swings without external biasing; limited to unipolar signal paths | Choose when system uses AC-coupled audio and board space allows extra capacitors |
Compared with TMUX1574RSVR and ADG822BRMZ-REEL, the DG2750DN1-T1-GE4 uniquely delivers verified (V+) − 5 V analog swing in UTMQFN-10, making it the only option among the three for true capacitorless audio routing in ultra-thin portable designs.

FAQ
What is the maximum analog signal voltage range supported by the DG2750DN1-T1-GE4?
The DG2750DN1-T1-GE4 supports an analog signal range from (V+) − 5 V to V+, confirmed across its full operating temperature range (-40 °C to +85 °C). At V+ = 2.7 V, this enables signals from -2.3 V to +2.7 V - sufficient for capacitorless microphone biasing and headphone driver output without external level-shifting circuitry. This specification is guaranteed by design per the Vishay datasheet E25-0258-Rev. H.
Does the DG2750DN1-T1-GE4 require external pull-up or pull-down resistors on its digital control inputs?
No, the DG2750DN1-T1-GE4 does not require external pull-up or pull-down resistors on IN1 or IN2. Its digital inputs have CMOS-compatible thresholds (1.4 V high, 0.6 V low at V+ = 2.7–4.3 V) and leakage current ≤ ±1 μA, allowing direct connection to FPGA, ASIC, or baseband processor GPIOs. Internal input structure eliminates need for external biasing, simplifying layout and reducing component count.
How does the UTMQFN-10 package of the DG2750DN1-T1-GE4 differ from the miniQFN-10 variant?
The DG2750DN1-T1-GE4 uses the UTMQFN-10 package (1.4 mm × 1.8 mm × 0.35 mm), which is 0.20 mm thinner than the standard miniQFN-10 (0.55 mm height). Both share identical 0.4 mm pitch, 10-pin layout, and thermal pad design, but the UTMQFN variant targets ultra-slim handhelds where Z-height is constrained. Pinout, electrical specs, and soldering profile are fully compatible between DG2750DN1-T1-GE4 and DG2750DN-T1-E4.
Can the DG2750DN1-T1-GE4 be used in bidirectional analog signal paths?
Yes, the DG2750DN1-T1-GE4 is explicitly designed as a bidirectional analog switch. Its CMOS construction and symmetric RON (0.45 Ω typical) ensure identical performance whether signal flows from COM to NO/NC or vice versa. This is validated in the datasheet's "Analog Switch" section and confirmed by THD+N < -98 dB and flat on-resistance vs. analog voltage curves - essential for line-level audio send/receive and sensor signal conditioning.
What is the latch-up immunity rating for the DG2750DN1-T1-GE4, and how is it tested?
The DG2750DN1-T1-GE4 provides >600 mA latch-up immunity, tested per JESD78 Class II (±600 mA) using the specified test method. This rating applies to all pins except COM/NO/NC terminals, where continuous current is limited to ±250 mA. The robustness stems from sub-micron CMOS process and internal protection structures, enabling reliable operation in noisy portable environments with transient coupling into analog or digital lines.
