Product details
Overview
DG3015DB-T2-E1 from Vishay Siliconix is a dual double-pole/double-throw (DPDT) monolithic CMOS analog switch optimized for low-voltage, high-bandwidth signal routing in portable electronics. It operates from 2.7 V to 3.3 V, delivers 0.8 Ω typical on-resistance, achieves 40 ns turn-on/35 ns turn-off times, and supports 100 MHz bandwidth with -67 dB off-isolation - enabling precise audio/video switching in space-constrained battery-powered systems.
For engineers reviewing the DG3015DB-T2-E1 datasheet, DG3015DB-T2-E1 pinout, DG3015DB-T2-E1 application, or DG3015DB-T2-E1 equivalent, key selection criteria include its MICRO FOOT 16-bump package footprint, guaranteed break-before-make timing, ±150 mA continuous channel current rating, and TTL/1.8 V logic compatibility for direct interfacing with modern baseband processors.
Technical Context
The DG3015DB-T2-E1 implements a dual DPDT topology with four independent COM/NO/NC switch sections per channel, each controlled by a single digital input (INA/INB) with active-high logic. Its JI2 low-voltage CMOS process ensures latchup immunity via epitaxial isolation and guarantees break-before-make operation across temperature (-40 °C to +85 °C).
Signal handling is bidirectional with full rail-to-rail analog range (0 V to V+), on-resistance flatness of 0.16 Ω, and channel matching (ΔRON) ≤ 0.15 Ω. Charge injection is limited to 7 pC, and off-capacitance is 63–67 pF per NC/NO terminal - critical for minimizing transient glitches and crosstalk in high-fidelity audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.3 V - enables direct integration with 3.3 V LDOs and avoids level-shifting in mobile SoC interfaces. |
| On-Resistance (RON) | 0.8 Ω typ. at V+ = 2.7 V - minimizes insertion loss and voltage drop in audio headset and speaker routing paths. |
| Bandwidth | 100 MHz (3 dB point) - supports composite video, USB 1.1, and high-speed analog sensor signals without attenuation. |
| Switching Time | tON = 40 ns, tOFF = 35 ns - ensures fast channel reconfiguration for dynamic audio path selection in real-time applications. |
| Off-Isolation | -67 dB at 1 MHz - suppresses signal leakage between inactive channels, preserving SNR in multi-source audio systems. |
| Charge Injection | 7 pC - limits voltage glitch on COM nodes during switching, reducing audible pop/click in headphone drivers. |
| Logic Compatibility | TTL and 1.8 V CMOS - allows direct control from application processors and baseband ICs without external translators. |
Pinout & Package
MICRO FOOT 16-bump package (4 × 4 mm, 0.5 mm pitch, 238 µm bump height) with Pb-free Sn/Ag/Cu bumps and non-solder-mask-defined copper landing pads. Package footprint complies with IPC-7351B density level A for reliable reflow soldering in fine-pitch portable PCB assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA, INB | Digital control inputs | Active-high logic pins controlling Channel A and B DPDT states; compatible with 1.8 V/3.3 V logic thresholds (VINH ≥ 2 V, VINL ≤ 0.4 V). |
| COM1–COM4 | Analog common terminals | Bidirectional signal ports connecting to source/load; support full 0 V to V+ analog swing with ±150 mA continuous current capability. |
| NO1–NO4 | Normally-open switch outputs | Connect to COM when corresponding IN = 1; exhibit 63 pF off-capacitance and <200 pF on-capacitance for minimal signal loading. |
| NC1–NC4 | Normally-closed switch outputs | Connect to COM when corresponding IN = 0; matched to NO terminals in RON and capacitance for symmetric routing performance. |
| V+ | Positive supply | Single 2.7–3.3 V rail powering analog and digital sections; supplies 1 µA quiescent current at room temperature. |
| GND | Ground reference | Common return for supply and logic; must be low-impedance to minimize ground bounce during fast switching transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | 0.16 Ω variation over 0–V+ analog range - maintains consistent gain and THD across volume-controlled audio paths. |
| Guaranteed break-before-make | Minimum 1 ns dead time between NC and NO closure - prevents momentary short-circuit during audio jack detection or mode switching. |
| Ultra-low charge injection | 7 pC maximum - reduces DC offset shift on sensitive amplifier inputs, eliminating need for post-switching calibration. |
| Rail-to-rail analog operation | Full 0 V to V+ signal handling - supports both single-ended and pseudo-differential audio signals without clipping. |
| RoHS-compliant MICRO FOOT | 16-bump, 4 × 4 mm footprint - saves >60% board area versus SOIC-16, enabling ultra-thin smartphone and wearable designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual DPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4677EUB+ | Higher RON (1.5 Ω typ.), larger 10-pin µMAX package (3 × 3 mm), 5 V only supply | Requires level-shifting for 3.3 V logic; unsuitable for space-constrained 2.7 V battery systems | Select only if 5 V system architecture and higher bandwidth (>200 MHz) are required |
| ADG732BRUZ | 32-channel SPST, not DPDT; 4 mm × 4 mm TSSOP; 3 V compatible but 2.5 Ω RON | Lacks integrated DPDT topology - requires 4× more devices and PCB area to replicate DG3015DB-T2-E1 functionality | Choose only for high-channel-count multiplexing where individual SPST control is mandatory |
Compared with MAX4677EUB+ and ADG732BRUZ, the DG3015DB-T2-E1 uniquely combines dual DPDT topology, 0.8 Ω RON, MICRO FOOT packaging, and native 2.7–3.3 V operation - making it the only solution that meets all three requirements simultaneously for portable audio routing.
