Product details
Overview
DG2524DN-T1-GE4 from Vishay Siliconix is a quad SPDT analog switch IC with enable control, designed for precision signal routing in low-voltage systems. It operates from 1.8 V to 5.5 V, delivers 0.4 Ω typical on-resistance at 2.7 V, supports rail-to-rail analog switching, and guarantees break-before-make timing-ideal for medical instrumentation and battery-powered data acquisition.
For engineers reviewing the DG2524DN-T1-GE4 datasheet, DG2524DN-T1-GE4 pinout, DG2524DN-T1-GE4 application, or DG2524DN-T1-GE4 equivalent, key selection criteria include its QFN-16 (3 mm × 3 mm) package, EN-controlled channel activation, 310 MHz bandwidth, and sub-1 nA off-leakage at +85 °C.
Technical Context
The DG2524DN-T1-GE4 implements four independent SPDT switches controlled by four logic inputs plus a global active-low EN pin, enabling synchronous channel enablement. Its CMOS architecture ensures bidirectional conduction, rail-to-rail signal handling, and guaranteed break-before-make timing to prevent signal shorting during state transitions.
It features low-threshold digital control (VINH = 1.2 V min, VINL = 0.3 V max at full temperature range), low charge injection (−19 pC), and matched on-resistance flatness (0.03 Ω typ) across the full analog voltage range-critical for high-fidelity multiplexing in precision ADC front-ends and audio routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.8 V to 5.5 V single supply-supports direct interfacing with 1.8 V, 3.3 V, and 5 V logic and analog rails. |
| On-Resistance | 0.4 Ω typ at 2.7 V-minimizes signal attenuation and gain error in sensor signal chains and precision DAC outputs. |
| Bandwidth | 310 MHz-enables clean switching of high-speed video, USB 1.1, or baseband communication signals without roll-off. |
| Off-Leakage | ±1 nA max at +85 °C-preserves accuracy in high-impedance pH sensors, thermocouple amplifiers, and electrometer-grade circuits. |
| Charge Injection | −19 pC-reduces settling error and glitch energy in sample-and-hold and multiplexed ADC applications. |
| THD + N | −100 dB at 1 kHz-ensures low distortion in audio path switching and high-fidelity test equipment signal routing. |
| Switch Capacitance | CON = 26 pF, COFF = 14.5 pF-balances low crosstalk (−89 dB at 100 kHz) and fast switching speed (tON = 38 μs typ). |
Pinout & Package
Package: QFN-16 (3 mm × 3 mm), exposed thermal pad (no electrical connection), lead (Pb)-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | IN1–IN4 logic inputs | Individual channel control lines; active-high, compatible with 1.8 V logic thresholds. |
| 5, 6, 8, 9 | NO1–NO4 normally-open terminals | Analog output paths closed when corresponding IN = high; low-capacitance routing nodes. |
| 7 | EN | Active-low global enable; disables all switches when high, reducing supply current to <60 μA. |
| 10, 11, 12, 13 | NC1–NC4 normally-closed terminals | Default analog paths closed when corresponding IN = low; matched RON and COFF to NO pins. |
| 14, 15, 16 | COM1–COM4 common terminals | Bidirectional analog signal ports; support rail-to-rail swing up to V+; require no level-shifting. |
| 16 (corner) | V+ | Single positive supply input; decoupling capacitor required near pin for stable switching performance. |
| Ground | GND | Pin 14 is GND; provides reference for logic and analog paths; shared return for all channels. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make guarantee | Prevents momentary shorting between NC and NO paths during transition-essential for fault-tolerant relay replacement. |
| Rail-to-rail analog switching | Supports input signals from GND to V+ without clipping-enables direct interface with op-amp outputs and SAR ADC inputs. |
| Low and flat on-resistance | 0.03 Ω typical RON flatness over full analog range-maintains consistent gain and linearity in programmable gain amplifier (PGA) configurations. |
| Power-down protection | Input and output pins remain high-impedance and clamped during V+ loss-prevents back-driving of powered subsystems. |
| ESD robustness | HBM >6 kV-survives handling and board-level ESD events without latch-up or parameter shift. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4618EUE+ | Higher on-resistance (0.8 Ω typ), wider supply range (2.7–12 V), no EN pin-requires external logic for global disable. | Suitable for higher-voltage industrial muxing but not optimal for 1.8 V battery systems. | Select DG2524DN-T1-GE4 for sub-2 V operation and integrated EN; choose MAX4618EUE+ only if 12 V tolerance is mandatory. |
| ADG1419BCPZ-REEL7 | Lower leakage (±5 pA typ), higher bandwidth (370 MHz), but requires dual supply (±15 V) or asymmetric rails-no 1.8 V logic compatibility. | Better for high-precision lab equipment, not portable or low-power designs. | DG2524DN-T1-GE4 is preferred for single-supply, low-voltage portability; ADG1419BCPZ-REEL7 fits high-end bench instruments needing ultra-low leakage. |
Compared with MAX4618EUE+ and ADG1419BCPZ-REEL7, DG2524DN-T1-GE4 uniquely combines 1.8 V logic compatibility, integrated EN, and sub-0.5 Ω RON in a 3 mm × 3 mm QFN-making it the only option optimized for space-constrained, battery-operated precision analog multiplexing.

FAQ
What is the maximum analog signal voltage range supported by DG2524DN-T1-GE4?
DG2524DN-T1-GE4 supports rail-to-rail analog signal switching from GND to V+, with absolute maximum ratings allowing signals up to (V+ + 0.3 V). For a 3.3 V supply, this enables ±0.3 V headroom-critical for preserving signal integrity in op-amp-driven sensor interfaces without external clamping diodes.
Does DG2524DN-T1-GE4 require external pull-up or pull-down resistors on its IN or EN pins?
No, DG2524DN-T1-GE4 does not require external biasing on IN or EN pins. Its logic inputs have guaranteed thresholds (VINH ≥ 1.2 V, VINL ≤ 0.3 V) and low input current (<1 μA), allowing direct connection to GPIOs of 1.8 V, 3.3 V, or 5 V microcontrollers without additional components.
How does the EN pin affect power consumption in DG2524DN-T1-GE4?
When EN is high, DG2524DN-T1-GE4 enters power-down mode with total supply current reduced to ≤60 μA across −40 °C to +85 °C. This enables significant energy savings in battery-powered systems during idle periods while maintaining fast wake-up (<70 μs tON) upon EN assertion.
Can DG2524DN-T1-GE4 be used to replace mechanical relays in low-voltage applications?
Yes, DG2524DN-T1-GE4 is qualified for relay replacement in low-voltage (<5.5 V), low-current (<±300 mA continuous) applications. Its break-before-make timing, 300 mA latch-up immunity (JESD78), and >6 kV HBM ESD rating provide robust solid-state switching with no contact wear, bounce, or coil drive complexity.
Is the exposed thermal pad on the QFN-16 package of DG2524DN-T1-GE4 electrically connected?
No, the exposed thermal pad on DG2524DN-T1-GE4's QFN-16 package has no electrical connection. It is intended solely for thermal dissipation and must be soldered to a PCB copper pour for optimal junction-to-board thermal resistance-verified per Vishay's package drawing 72208 (Variation 2).
