Product details
Overview
DG9422EDV-T1-GE3 from Vishay Siliconix is a monolithic single-pole, single-throw (SPST) analog switch with normally open (NO) configuration, designed for bidirectional rail-to-rail signal routing in precision instrumentation and portable systems. It delivers 1.7 Ω typical on-resistance at +12 V, 161 MHz bandwidth, and operates from +3 V to +16 V single supply or ±3 V to ±8 V dual supply. Its low charge injection (19 pC) and high off-isolation (−58 dB) support high-fidelity data acquisition and audio switching.
For engineers reviewing the DG9422EDV-T1-GE3 datasheet, DG9422EDV-T1-GE3 pinout, DG9422EDV-T1-GE3 application, or DG9422EDV-T1-GE3 equivalent, key selection criteria include verified SPST NO functionality, TSOP-6 package compatibility, guaranteed −40 °C to +85 °C operation, and confirmed 2.4 V logic-compatible control threshold - all critical for low-distortion signal path design in medical, test, and battery-powered equipment.
Technical Context
The DG9422EDV-T1-GE3 employs high-density BiCMOS process technology to achieve flat, low on-resistance across its full analog input range (0–12 V single supply), enabling excellent linearity and minimal insertion loss. Its bidirectional conduction supports symmetric signal routing without polarity constraints.
Control logic accepts 2.4 V high and 0.8 V low thresholds independent of supply voltage, and inputs tolerate overvoltage up to V+, simplifying interface with mixed-voltage microcontrollers. Switching performance is characterized across temperature and supply conditions: tON/tOFF remain ≤41 ns/22 ns at +12 V, and bandwidth sustains 179 MHz under ±5 V dual supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | SPST, normally open (NO) - enables signal path only when control input is logic high |
| On-resistance (RDS(on)) | 1.7 Ω typical at +12 V - ensures minimal voltage drop and signal attenuation in precision analog paths |
| Bandwidth | 161 MHz (single +12 V) / 179 MHz (±5 V) - supports high-speed video, RF sampling, and fast data acquisition |
| Charge injection | 19 pC typical - reduces glitch-induced error in sample-and-hold and multiplexed ADC front-ends |
| Off-isolation | −58 dB at 1 MHz - suppresses crosstalk between adjacent channels in dense signal routing |
| Supply range | +3 V to +16 V single or ±3 V to ±8 V dual - accommodates legacy 5 V, modern 3.3 V, and industrial 12 V systems |
| Logic compatibility | 2.4 V logic-high threshold - interfaces directly with 3.3 V and 5 V CMOS outputs without level shifting |
Pinout & Package
Package: 6-pin TSOP (MO-193C), 3.05 mm × 2.85 mm × 1.0 mm body, lead pitch 0.95 mm, RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | Accepts 0.8 V / 2.4 V logic thresholds; tolerates voltage up to V+; controls NO switch state |
| 2 - NO | Analog output terminal | Open-circuit when IN = low; connects to COM when IN = high; rated for ±50 mA continuous |
| 3 - GND | Ground reference | Common return for control logic and substrate bias; must be low-impedance for noise immunity |
| 4 - V− | Negative supply rail | Required for dual-supply operation (±3 V to ±8 V); tied to GND for single-supply use |
| 5 - COM | Common analog terminal | Bidirectional signal port; connects to NO when switch is on; blocks signals up to supply rails when off |
| 6 - V+ | Positive supply rail | Supplies internal circuitry and defines analog signal ceiling (0 to V+ for single supply) |
Key Features
| Feature | Design Value |
|---|---|
| Low and flat on-resistance | 1.7 Ω typical, <3.2 Ω max over full analog range - preserves signal integrity in gain-setting and filter networks |
| Rail-to-rail bidirectional switching | Supports analog signals from V− to V+ in both directions - eliminates polarity restrictions in AC-coupled or bipolar systems |
| High bandwidth and low capacitance | 161 MHz −3 dB bandwidth with CCOM(on) = 68 pF - minimizes phase shift and group delay in wideband applications |
| Ultra-low leakage | ±1.06 nA max switch-off leakage at full temperature range - prevents DC error accumulation in high-impedance sensor interfaces |
| Overvoltage-tolerant control input | IN accepts voltages up to V+ - enables direct connection to higher-voltage microcontroller GPIOs without external protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUT+T | SPST NO, 3.5 Ω RDS(on) at +5 V, 125 MHz bandwidth, SOT-23-6 package | Higher on-resistance and lower bandwidth limit use in >10 MHz signal paths and precision gain control | Select when footprint compatibility with SOT-23-6 is required and 3.5 Ω on-resistance is acceptable for system accuracy budget |

FAQ
What is the maximum analog signal voltage range supported by DG9422EDV-T1-GE3?
DG9422EDV-T1-GE3 supports analog signals from V− to V+ - up to 0 V to +12 V with single +12 V supply, or −5 V to +5 V with ±5 V dual supply. Absolute maximum analog voltage at any terminal is (V−) − 0.3 V to (V+) + 0.3 V, with clamping diodes limiting excursion beyond rails. This rail-to-rail capability makes DG9422EDV-T1-GE3 suitable for both unipolar and bipolar signal conditioning.
Is DG9422EDV-T1-GE3 compatible with 3.3 V logic control signals?
Yes, DG9422EDV-T1-GE3 is fully compatible with 3.3 V logic: its input recognizes logic high at ≥2.4 V and logic low at ≤0.8 V, well within standard 3.3 V CMOS levels. No level-shifting circuitry is needed, and the control input tolerates voltages up to V+, allowing direct interface with 3.3 V microcontrollers even when V+ is +12 V. This simplifies system integration in mixed-voltage designs.
How does DG9422EDV-T1-GE3 perform at low supply voltages like +3 V?
At +3 V single supply, DG9422EDV-T1-GE3 maintains functional operation with 7.3 Ω typical on-resistance and 124 ns typical turn-on time. While RDS(on) increases and switching speed slows versus +12 V operation, the device remains viable for low-power portable systems where signal bandwidth requirements are modest (<1 MHz) and voltage headroom is constrained. Full −40 °C to +85 °C specification applies across all supply ranges.
Does DG9422EDV-T1-GE3 require a negative supply to operate?
No, DG9422EDV-T1-GE3 operates fully on single supply: V− can be tied to GND while V+ supplies +3 V to +16 V. Dual supply (±3 V to ±8 V) is optional and used only when bipolar analog signal handling (e.g., ±2.5 V audio) is required. The TSOP-6 pinout accommodates both configurations without hardware change - V− is simply left unconnected or grounded per application need.
What is the thermal performance and power dissipation limit of DG9422EDV-T1-GE3?
DG9422EDV-T1-GE3 has a maximum power dissipation of 570 mW in the TSOP-6 package at 25 °C ambient, derating linearly by 7 mW/°C above that temperature. With typical supply currents below 1 μA and on-resistance of 1.7 Ω, self-heating is negligible under normal signal loads (<50 mA). The device is specified for operation from −40 °C to +85 °C, and thermal resistance (θJA) is optimized for surface-mount PCB layouts with standard copper pour.
