Product details
Overview
DG612EEQ-T1-GE4 from Vishay Siliconix is a quad SPST analog switch with normally open (NO) configuration, designed for precision signal routing in high-speed, low-distortion applications. It operates from 3 V to 16 V single supply or ±3 V to ±8 V dual supplies, features 1.4 pC typical charge injection, 3 pF off-capacitance, 23 ns turn-on time, and 1 GHz 3 dB bandwidth - enabling use in automated test equipment and medical instrumentation.
For engineers reviewing the DG612EEQ-T1-GE4 datasheet, DG612EEQ-T1-GE4 pinout, DG612EEQ-T1-GE4 application, or DG612EEQ-T1-GE4 equivalent, key selection criteria include rail-to-rail analog signal handling, guaranteed 2 V logic-high compatibility at +5 V/±5 V, -59 dB off-isolation at 10 MHz, and operation across -40 °C to +125 °C.
Technical Context
The DG612EEQ-T1-GE4 implements four independent, bidirectional SPST switches with complementary control logic: logic high enables conduction (ON), logic low disables (OFF). All switches exhibit matched on-resistance (ΔRDS(on) ≤ 2.5 Ω at room temperature) and flat on-resistance (≤ 20 Ω variation over full analog range).
It supports both single-supply (e.g., +5 V, +3 V) and dual-supply (e.g., ±5 V) operation with fully specified performance at each condition. Input thresholds are guaranteed at 1.4 V (for +3 V supply) and 2 V (for +5 V or ±5 V), ensuring reliable CMOS/TTL interfacing without level-shifting.

FAQ
What is the maximum operating temperature for DG612EEQ-T1-GE4?
The DG612EEQ-T1-GE4 is fully specified and qualified for continuous operation from -40 °C to +125 °C. This extended temperature range is validated per Vishay's reliability testing and applies to all electrical parameters in the datasheet, including on-resistance, charge injection, and switching speed - making DG612EEQ-T1-GE4 suitable for under-hood automotive and industrial control applications.
Does DG612EEQ-T1-GE4 support dual-supply operation?
Yes, DG612EEQ-T1-GE4 supports dual-supply operation from ±3 V to ±8 V. It is fully characterized at ±5 V, with guaranteed performance for analog signal range (±5 V), on-resistance (72 Ω typ), and dynamic parameters (tON = 23 ns). The device maintains rail-to-rail analog handling and logic compatibility across both single- and dual-supply configurations.
What is the logic configuration of DG612EEQ-T1-GE4?
DG612EEQ-T1-GE4 is a normally open (NO) quad SPST switch: each switch conducts (ON) when its corresponding INx pin is driven high (≥2 V at +5 V supply), and opens (OFF) when INx is low (≤0.8 V). This matches standard active-high digital control schemes and eliminates need for external inverters in most microcontroller interfaces.
How does DG612EEQ-T1-GE4 minimize signal distortion in audio or sensor paths?
DG612EEQ-T1-GE4 minimizes distortion via 1.4 pC typical charge injection, 3 pF off-capacitance, and 0.13% THD at 20 Hz–20 kHz. Its flat on-resistance (≤20 Ω variation) and matched channels (ΔRDS(on) ≤ 2.5 Ω) preserve amplitude accuracy and phase coherence - critical for high-fidelity sensor conditioning and audio multiplexing where DG612EEQ-T1-GE4 is deployed.
Is DG612EEQ-T1-GE4 pin-compatible with DG611EEQ-T1-GE4?
No, DG612EEQ-T1-GE4 is not pin-compatible with DG611EEQ-T1-GE4. Although both share the same 16-pin TSSOP package and pinout numbering, their internal switch configurations differ: DG611E is normally closed (NC), while DG612E is normally open (NO). Swapping them requires logic inversion in the control signals to maintain functional equivalence - physical pin alignment does not guarantee functional drop-in replacement.
