Product details

Overview

DG2532DQ-T1-E3 from Vishay Siliconix is a dual SPDT analog switch optimized for low-voltage battery-powered systems, featuring 0.4 Ω on-resistance at 2.7 V, -69 dB off-isolation at 100 kHz, and guaranteed break-before-make timing. It operates from 1.8 V to 5.5 V and interfaces directly with 1.6 V logic, enabling use in cellular phone audio routing and headset switching.

For engineers reviewing the DG2532DQ-T1-E3 datasheet, DG2532DQ-T1-E3 pinout, DG2532DQ-T1-E3 application, or DG2532DQ-T1-E3 equivalent, key selection criteria include on-resistance matching (<0.05 Ω), flatness (<0.2 Ω), fast switching (t_ON/t_OFF = 40/35 ns), ESD protection (>2000 V), and MSOP-10 space-constrained packaging.

Technical Context

The DG2532DQ-T1-E3 implements two independent SPDT switches with complementary control logic: IN1/IN2 high enables NO1/NO2 conduction while disabling NC1/NC2. Its CMOS process includes an epitaxial layer to prevent latchup, and all analog terminals (COM/NO/NC) support bidirectional signal flow with rail-to-rail voltage range (0 to V+).

Dynamic performance is characterized by guaranteed break-before-make timing (t_d = 1–4 ns), low charge injection (54 pC), and minimal crosstalk (-69 dB at 100 kHz). Supply current remains ultra-low (1.0 µA max) across -40 °C to +85 °C, supporting always-on portable functions.

Key Specifications

Parameter	Value and Actual Design Meaning
On-resistance (r_ON)	0.4 Ω at 2.7 V - ensures minimal signal attenuation and voltage drop in audio/video paths
Off-isolation (OIRR)	-69 dB at 100 kHz - suppresses coupling between inactive channels in multi-source routing
Switching time (t_ON/t_OFF)	40 ns / 35 ns - supports high-speed signal reconfiguration without glitching
Supply voltage range	1.8 V to 5.5 V - compatible with Li-ion, coin-cell, and USB-powered systems
ESD protection	>2000 V HBM - withstands handling and board-level electrostatic events without damage
Logic threshold (V_INH/V_INL)	1.4 V / 0.5 V - interoperable with 1.6 V–3.3 V digital controllers including low-voltage DSPs
On-resistance matching	<0.05 Ω - maintains channel-to-channel signal fidelity in differential or stereo applications

Pinout & Package

Packaged in a 3 mm × 3 mm MSOP-10 surface-mount package with exposed thermal pad (not electrically connected), the DG2532DQ-T1-E3 supports automated assembly and efficient heat dissipation in dense layouts.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 4, 6, 7, 9	NC1, COM2, IN2, GND, IN1, COM1	No-connect (NC1/NC2) pins are internally unconnected; COM1/COM2 serve as common analog I/O ports
2, 8, 10	NO2, V+, NO1	NO1/NO2 are normally-open switch outputs; V+ supplies analog/digital rails; GND is system reference
5	NC2	No-connect terminal - must be left floating or tied to GND per layout best practice

Key Features

Feature	Design Value
Bidirectional analog conduction	Enables full-duplex audio routing without polarity constraints or external biasing
Guaranteed break-before-make	Prevents momentary short-circuit between NC and NO paths during state transition
On-resistance flatness <0.2 Ω	Maintains consistent gain and THD across full analog input range (0–V+)
Low charge injection (54 pC)	Minimizes voltage glitches at COM node during switching - critical for precision ADC front-ends
Rail-to-rail analog range	Supports signals from GND to V+ without clipping - essential for single-supply portable audio

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4682EUB+	Higher r_ON (0.8 Ω typ at 3 V); no guaranteed break-before-make; 10-pin µMAX package	Less suitable for glitch-sensitive audio; requires different footprint and layout	Select when cost sensitivity outweighs on-resistance and timing guarantees
ADG732BRUZ	32-channel single-pole; higher supply range (1.8–5.5 V); 0.8 Ω r_ON; TSSOP-48 package	Designed for high-channel-count data acquisition, not compact dual-path routing	Choose only when scaling beyond two SPDT paths or requiring integrated serial interface

Compared with MAX4682EUB+ and ADG732BRUZ, the DG2532DQ-T1-E3 provides the lowest on-resistance (0.4 Ω), guaranteed break-before-make timing, and smallest footprint (MSOP-10), making it optimal for space-constrained, low-distortion portable audio and battery-powered signal routing where channel count is fixed at two SPDTs.

FAQ

What is the maximum analog signal voltage range supported by the DG2532DQ-T1-E3?

The DG2532DQ-T1-E3 supports analog signals from GND to V+, with absolute maximum ratings allowing V_COM, V_NO, and V_NC to swing from -0.3 V to (V+ + 0.3 V). At V+ = 3.0 V, this yields a usable analog range of 0 V to 3.0 V - ideal for single-supply audio and sensor interfaces. The DG2532DQ-T1-E3 achieves rail-to-rail conduction without level-shifting circuitry.

Does the DG2532DQ-T1-E3 require external pull-up or pull-down resistors on its IN1/IN2 control inputs?

No, the DG2532DQ-T1-E3 does not require external biasing on IN1 or IN2. Its input thresholds are specified as V_INH = 1.4 V (min) and V_INL = 0.5 V (max), ensuring compatibility with 1.6 V–3.3 V logic families. The DG2532DQ-T1-E3 draws only 1.0 µA supply current, so high-impedance GPIOs can drive the inputs directly without loading concerns.

How does the DG2532DQ-T1-E3 handle signal directionality in analog paths?

The DG2532DQ-T1-E3 supports fully bidirectional analog conduction: current flows equally well from COM to NO/NC or vice versa when the switch is on. This eliminates polarity constraints in AC-coupled audio or differential sensor paths. The DG2532DQ-T1-E3 maintains matched on-resistance (<0.05 Ω) and flatness (<0.2 Ω) regardless of signal direction or voltage level.

Is the DG2532DQ-T1-E3 pin-compatible with the DG2531DQ-T1-E3?

No, the DG2532DQ-T1-E3 is not pin-compatible with the DG2531DQ-T1-E3. While both use MSOP-10 packages, their pinouts differ: DG2532 connects NO1/NO2 to pins 6 and 2, whereas DG2531 places them on pins 8 and 10. The DG2532DQ-T1-E3 also swaps NC1/NC2 and COM1/COM2 positions. Board redesign is required for substitution.

What thermal considerations apply to the DG2532DQ-T1-E3 in continuous operation?

The DG2532DQ-T1-E3 has a maximum power dissipation of 320 mW in MSOP-10 at T_A ≤ 70 °C, derating linearly by 4.0 mW/°C above that temperature. With typical r_ON = 0.4 Ω and I_LOAD = 100 mA, power dissipation is just 4 mW per channel - well within limits. The DG2532DQ-T1-E3's epitaxial construction prevents latchup even under transient overvoltage conditions.
