Product details

Overview

DG2750DN-T1-E4 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, delivering 0.45 Ω typical on-resistance, < −98 dB THD+N, and negative-swing audio capability down to −2.5 V without coupling capacitors - deployed in portable media players and cellular handsets.

For engineers reviewing the DG2750DN-T1-E4 datasheet, DG2750DN-T1-E4 pinout, DG2750DN-T1-E4 application, or DG2750DN-T1-E4 equivalent, key selection criteria include guaranteed 1.4 V logic compatibility at 2.7–5.5 V supply, 600 mA latch-up immunity per JESD78, and miniQFN-10 (1.4 mm × 1.8 mm × 0.55 mm) packaging with Pb-free NiPdAu terminations.

Technical Context

The DG2750DN-T1-E4 implements two independent SPDT switches using sub-micron CMOS process, enabling bidirectional signal flow with rail-to-rail analog voltage support from (V+ − 5) V to V+, and break-before-make timing of 800–1160 ns at 3 V supply.

Its control interface accepts 1.4 V logic-high inputs across full temperature range (−40 °C to +85 °C), while maintaining < 2 μA quiescent supply current and 4 pC typical charge injection - critical for low-distortion audio switching in battery-powered systems.

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
Texas Instruments TS5A23157DCUR	0.9 Ω typical R_ON, 1.65–5.5 V supply, 6-pin SC70 package - higher on-resistance, smaller footprint but no negative-swing capability.	Not suitable for true bipolar audio paths; requires DC-blocking caps for signals below GND.	Select when board space is primary constraint and audio swing stays within 0 V to V+ range.
Analog Devices ADG884BRMZ	0.35 Ω typical R_ON, 1.8–5.5 V supply, 10-lead MSOP - lower on-resistance but lacks guaranteed 1.4 V logic compatibility below 1.8 V.	Requires ≥1.8 V logic interface; not interoperable with 1.4 V–1.6 V control buses.	Select when ultra-low R_ON is critical and host logic operates at ≥1.8 V.

Compared with TS5A23157DCUR and ADG884BRMZ, the DG2750DN-T1-E4 uniquely combines 0.45 Ω R_ON, −2.5 V analog swing, and 1.4 V logic compatibility in a 1.4 mm × 1.8 mm QFN - making it the only option for space-constrained, low-voltage, true-bipolar audio routing.

FAQ

What is the maximum analog signal voltage range supported by the DG2750DN-T1-E4?

The DG2750DN-T1-E4 supports an analog signal range from (V+ − 5) V to V+, which translates to −2.5 V minimum when V+ = 2.7 V. This allows true negative-swing audio signals without DC-blocking capacitors. The absolute maximum rating for COM/NO/NC terminals is (V+ + 0.3) V or −2.5 V, whichever is higher - verified per Absolute Maximum Ratings table in Vishay Document 64736.

Does the DG2750DN-T1-E4 require separate analog and digital supplies?

No, the DG2750DN-T1-E4 operates from a single 1.6 V to 5.5 V supply (V+) that powers both analog and digital circuitry. Its design eliminates the need for dual supplies or level shifters, simplifying power architecture in portable systems. This is confirmed in the "DESCRIPTION" section and "Power Supply" specifications of the DG2750DN-T1-E4 datasheet (Rev. H, May 2025).

What is the logic-compatible voltage threshold for DG2750DN-T1-E4 control inputs?

The DG2750DN-T1-E4 guarantees logic-high recognition at 1.4 V minimum when V+ is between 2.7 V and 5.5 V - enabling direct interface with 1.8 V and lower-voltage DSPs, microcontrollers, and ASICs. This specification is explicitly stated in the "Digital Control" section and Truth Table of the DG2750DN-T1-E4 datasheet (Document 64736).

How does the DG2750DN-T1-E4 achieve low THD+N in audio applications?

The DG2750DN-T1-E4 achieves < −98 dB THD+N through sub-micron CMOS process optimization, low on-resistance flatness (0.3 Ω), and minimized charge injection (4 pC), all contributing to linear signal transfer across 20 Hz–20 kHz. Measured under standard conditions (VCOM = 0.5 V_P-P, R_S = R_L = 600 Ω, DC bias = 0 V), this value is documented in the "Dynamic Characteristics" table of the DG2750DN-T1-E4 datasheet.

Is the DG2750DN-T1-E4 RoHS-compliant and halogen-free?

Yes, the DG2750DN-T1-E4 is fully RoHS-compliant and halogen-free, as explicitly declared in the "DESCRIPTION" section of its datasheet (Rev. H). The "-E4" suffix denotes Pb-free NiPdAu termination, and material compliance aligns with JEDEC standards and Vishay's environmental policy (Document 99912).
