Product details
Overview
DG2501DB-T2-GE1 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, operating from 1.8 V to 5.5 V single supply, featuring 200 Ω max RDS(on) at 5 V, 1 nA max off-leakage at +85 °C, and rail-to-rail signal handling - ideal for low-power portable healthcare and instrumentation signal routing.
For engineers reviewing the DG2501DB-T2-GE1 datasheet, DG2501DB-T2-GE1 pinout, DG2501DB-T2-GE1 application, or DG2501DB-T2-GE1 equivalent, key selection criteria include guaranteed break-before-make timing, WCSP16 package compatibility with high-density PCB layouts, low charge injection (–2 pC typ. at 5 V), and TTL/CMOS logic compatibility across full temperature range (–40 °C to +85 °C).
Technical Context
The DG2501DB-T2-GE1 implements four independent NC SPST switches in monolithic silicon, each with matched on-resistance (≤10 Ω ΔRon at 5 V) and symmetric bidirectional conduction. Its control logic thresholds are specified at 1.8 V (VINH) and 0.5 V (VINL) under 5 V supply, ensuring robust digital interface operation.
Designed for precision analog signal paths, it delivers 2.6 pF typical CD(off), –84 dB off-isolation at 1 MHz, and 550 MHz 3 dB bandwidth - enabling high-fidelity switching in sample-and-hold and AFE multiplexing without signal degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | Quad SPST NO, 60 Ω RDS(on) max at 5 V, SO-16 package (4.9 mm × 6.0 mm) | Requires PCB redesign due to larger footprint and opposite logic polarity (NO vs NC) | Select when lower on-resistance is prioritized over NC functionality and board area constraints |
| ADG712BRUZ | Quad SPST NO, 4 Ω RDS(on) max at 5 V, TSSOP-16 package (5.0 mm × 4.4 mm) | Not NC-configured; lacks break-before-make guarantee; higher leakage (5 nA at +85 °C) | Choose for ultra-low RDS(on) in non-fail-safe signal paths where NC behavior is not required |
Compared with MAX4617EUA+ and ADG712BRUZ, DG2501DB-T2-GE1 uniquely delivers NC functionality in a 1.44 mm² WCSP package with guaranteed break-before-make timing and sub-nA leakage - making it optimal for space- and safety-critical portable medical AFEs where default-closed signal integrity is mandatory.

FAQ
What is the maximum allowable supply voltage for DG2501DB-T2-GE1?
The absolute maximum supply voltage (V+) for DG2501DB-T2-GE1 is +6 V, but the device is fully specified and characterized for reliable operation from 1.8 V to 5.5 V. Operating above 5.5 V voids parametric guarantees and risks permanent damage per the Absolute Maximum Ratings table in Vishay document 62962. For long-term reliability in portable medical devices, use 3.0 V or 5.0 V nominal supplies.
Does DG2501DB-T2-GE1 support rail-to-rail analog signal switching?
Yes, DG2501DB-T2-GE1 supports true rail-to-rail analog signal handling: its analog input/output range extends from 0 V to V+, verified at both 3 V and 5 V supplies. This allows seamless interfacing with sensors, op-amps, and ADCs operating at full supply rails without external level-shifting circuitry - a key enabler for low-voltage portable healthcare systems.
How does the normally closed (NC) configuration of DG2501DB-T2-GE1 affect its control logic?
In DG2501DB-T2-GE1, each of the four SPST switches is normally closed, meaning the switch conducts when its corresponding INx input is logic low (≤0.5 V at 5 V supply). A logic high (≥1.8 V) opens the switch. This inverse logic simplifies fail-safe designs - for example, loss of control signal defaults to signal pass-through, critical in medical monitoring AFEs where uninterrupted sensor data flow is essential.
What is the thermal resistance (θJA) of DG2501DB-T2-GE1 in its WCSP16 package?
The thermal resistance (θJA) of DG2501DB-T2-GE1 is 80 °C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC PCB mounting conditions (2-layer board, 1 in² copper pad). In compact wearable PCBs with limited copper area, actual junction temperature rise may exceed this - thermal simulation and localized ground plane enhancement are recommended for continuous 5 mA per channel operation at +85 °C ambient.
Is DG2501DB-T2-GE1 pin-compatible with DG2502DB-T2-GE1 or DG2503DB-T2-GE1?
Yes, DG2501DB-T2-GE1 shares identical WCSP16 pinout, package dimensions, and footprint with DG2502DB-T2-GE1 (NO) and DG2503DB-T2-GE1 (dual NC/NO), enabling hardware reuse across variants. However, logic polarity differs: DG2501DB-T2-GE1 is NC (low = ON), DG2502DB-T2-GE1 is NO (high = ON), and DG2503DB-T2-GE1 mixes both. Firmware or schematic updates are required to match switch behavior.
