Product details

Overview

DG9425DQ-T1-E3 from Vishay Siliconix is a low-voltage, dual-supply, quad SPST analog switch with break-before-make switching action, 1.7 Ω typical on-resistance at 12 V single supply, 42 ns turn-on time, and ±3 V to ±6 V dual-supply operation - used for precision audio signal routing in professional mixing consoles.

For engineers reviewing the DG9425DQ-T1-E3 datasheet, DG9425DQ-T1-E3 pinout, DG9425DQ-T1-E3 application, or DG9425DQ-T1-E3 equivalent, key selection criteria include logic polarity (active-low control), TSSOP-16 package thermal resistance (178 °C/W), and guaranteed -56 dB off-isolation at 1 MHz - critical for high-fidelity analog multiplexing where crosstalk must remain below -77 dB.

Technical Context

The DG9425DQ-T1-E3 implements four independent single-pole-single-throw switches with complementary logic control versus DG9424 (i.e., logic '0' = ON, logic '1' = OFF), fabricated using BiCMOS process for low R_DS(on) flatness across the analog signal range. It supports rail-to-rail analog signals from 0 V to 12 V (single supply) or ±5 V (dual supply), with internal ESD protection rated at 2000 V HBM.

Its dynamic performance includes 42 ns t_ON and 28 ns t_OFF (RL = 300 Ω, CL = 35 pF), 38 pC charge injection, and 89 pF channel-on capacitance - enabling <280 MHz -3 dB bandwidth and minimal signal distortion in video and high-speed data acquisition paths.

Key Specifications

Parameter	Value and Actual Design Meaning
On-resistance	1.7 Ω typical at V+ = 12 V - ensures ≤ 0.1% signal attenuation in 50 Ω systems
Turn-on time	42 ns typical - supports >10 MSPS switching in ADC front-end multiplexers
Off-isolation	-56 dB at 1 MHz - suppresses inter-channel leakage to <250 µV in 1 V_PP audio paths
Analog signal range	0 to 12 V (single supply) or ±5 V (dual supply) - accommodates full-range line-level and sensor outputs
Logic compatibility	TTL/CMOS - interfaces directly with FPGA I/O banks without level-shifting
ESD rating	2000 V HBM - meets IEC 61000-4-2 Level 2 for board-level handling robustness
Supply current	0.02 μA typical at room temperature - enables battery-powered portable test equipment

Pinout & Package

Package: 16-pin TSSOP (JEDEC MO-153, 5.0 mm × 6.4 mm × 1.1 mm), thermal resistance θ_JA = 178 °C/W, rated for -40 °C to +85 °C operation.

Pin/Terminal	Circuit Role	Design Meaning
IN1–IN4	Digital control inputs	Active-low logic per DG9425 truth table: INx = 0 → corresponding switch ON
COM1–COM4	Analog common terminals	Switch output nodes; each connects to NCx/NOx pair when enabled
NC1–NC4	Normally closed switch terminals	Internally connected to COMx when INx = 0; open when INx = 1
NO1–NO4	Normally open switch terminals	Internally disconnected from COMx when INx = 0; connected when INx = 1
V+, V-	Analog supply rails	Support dual-supply operation (±3 V to ±6 V) or single supply (3–12 V)
GND	Ground reference	Return path for digital logic and substrate bias; separate from analog ground plane in layout
VL	Logic supply voltage	Accepts 3 V to V+; sets input threshold - enables mixed-voltage system interfacing

Key Features

Feature	Design Value
Break-before-make switching	Guaranteed 2 ns minimum t_D prevents momentary shorting between NC/NO paths during transition
Flat R_DS(on) vs. voltage	≤ ±0.3 Ω variation over full analog range - maintains consistent gain in precision instrumentation
Low charge injection	38 pC typical - limits voltage glitch to <40 mV on 1 nF load, preserving ADC accuracy
High off-isolation & crosstalk	-56 dB OIRR and -77 dB XTalk at 1 MHz - isolates channels in multi-source audio routing
BiCMOS fabrication	Enables simultaneous low R_DS(on), fast switching, and low leakage (<0.2 nA) - no process trade-offs

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad SPST analog switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4617ESE+	Higher R_ON (3.5 Ω typ), slower t_ON (75 ns), no dual-supply support	Limited to single-supply 5 V systems; unsuitable for ±5 V audio or wide-range sensor interfaces	Select when cost sensitivity outweighs speed and supply flexibility requirements
ADG1419BRUZ	Lower R_ON (1.3 Ω), higher supply voltage (up to ±15 V), but larger 20-lead TSSOP package	Supports industrial ±10 V signal chains but requires PCB redesign due to pin count and layout	Select for high-voltage precision applications where 16-pin footprint is not constrained

Compared with DG9425DQ-T1-E3, MAX4617ESE+ trades speed and dual-supply capability for lower unit cost, while ADG1419BRUZ extends voltage range and reduces on-resistance at the expense of package size and layout compatibility - making DG9425DQ-T1-E3 optimal for space-constrained, mixed-supply audio/data routing.

FAQ

What is the logic polarity of DG9425DQ-T1-E3 compared to DG9424DQ-T1-E3?

The DG9425DQ-T1-E3 uses inverted control logic: a logic low (0 V) on INx turns the corresponding switch ON, whereas DG9424DQ-T1-E3 activates with a logic high. This complementary pairing allows designers to implement redundant or differential switching schemes without external inverters - a key feature confirmed in the Vishay S16-0453 Rev. H truth table for DG9425DQ-T1-E3.

Does DG9425DQ-T1-E3 support dual-supply operation, and what are the valid voltage ranges?

Yes, DG9425DQ-T1-E3 supports dual-supply operation from ±3 V to ±6 V, with guaranteed performance at ±5 V per the datasheet's Dual Supply ±5 V specifications table. The device maintains 2 Ω typical R_ON, 48 ns t_ON, and -56 dB off-isolation under these conditions - enabling true bipolar signal switching in audio codecs and sensor front-ends.

What is the maximum analog signal voltage that can be applied to DG9425DQ-T1-E3 pins?

The absolute maximum analog signal voltage on IN, COM, NC, or NO pins is (V−) − 0.3 V to (V+) + 0.3 V, per the Absolute Maximum Ratings table. For example, with V+ = 12 V and V− = 0 V, signals may swing from −0.3 V to +12.3 V; with ±5 V supplies, the safe range is −5.3 V to +5.3 V - clamped internally by ESD diodes.

Can DG9425DQ-T1-E3 be used in battery-powered portable equipment?

Yes, DG9425DQ-T1-E3 draws only 0.02 μA typical positive supply current at room temperature and operates down to 2.7 V single supply, making it suitable for portable test gear and handheld audio interfaces. Its 0.2 nA max switch leakage also minimizes battery drain in always-on signal paths - verified in the Single Supply 3 V specifications table.

Is the TSSOP-16 package of DG9425DQ-T1-E3 lead-free and RoHS-compliant?

Yes, the "-E3" suffix in DG9425DQ-T1-E3 denotes a lead-free, RoHS-compliant finish per Vishay specification S16-0453 Rev. H. The package uses matte tin plating over copper leadframe and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing standard reflow without baking.
