詳細說明

General DescriptionMaxim’s redesigned DG417/DG418/DG419 precision, CMOS, monolithic analog switches now feature guaanteed on-resistance matching (3Ω max) between switches and guaranteed on-resistance flatness over the signal range (4Ω max). These switches conduct equally well in either direction and guarantee low charge injection, low power consumption, and an ESD tolerance of 2000V minimum per Method 3015.7. The new design offers low off-leakage current over temprature (less than 5nA at +85°C).The DG417/DG418 are single-pole/single-throw (SPST) switches. The DG417 is normally closed, and the DG418 is normally open. The DG419 is single pole/double-throw (SPDT) with one normally closed switch and one normally open switch. Switching times are less than 175ns max for tON and less than 145ns max for tOFF. Operation is from a single +10V to +30V supply, or bipolar ±4.5V to ±20V supplies. The improved DG417/DG418/DG419 are fabricated with a 44V silicon-gate process.New Features♦ Plug-In Upgrades for Industry-Standard DG417/DG418/DG419♦ Improved RDS(ON) Match Between Channels (3Ω max, DG419 only)♦ Guaranteed RFLAT(ON) Over Signal Range (4Ω max)♦ Improved Charge Injection (10pC max)♦ Improved Off-Leakage Current Over Temperature (<5nA at +85°C)♦ Withstand Electrostatic Discharge (2000V min) per Method 3015.7Existing Features♦ Low RDS(ON) (35Ω max)♦ Single-Supply Operation +10V to +30V Bipolar-Supply Operation ±4.5V to ±20V♦ Low Power Consumption (35µW max)♦ Rail-to-Rail Signal Handling♦ TTL/CMOS-Logic CompatibleApplications Sample-and-Hold Circuits Communications Systems Test Equipment Battery-Operated Systems Modems Fax Machines Guidance and Control Systems PBX, PABX Audio Signal Routing Military Radios

常見問題解答

What is DG419DJ?

The DG419DJ is a precision quad single-pole, single-throw (4 x SPST) analog switch designed by Vishay. It is ideal for applications requiring high precision signal routing, such as test and measurement equipment, data acquisition systems, and precision instrumentation.

How Does DG419DJ Work?

The DG419DJ works by providing a low resistance, low distortion path for analog signals to be switched between different channels. It features low charge injection and low on-resistance, ensuring minimal impact on the signal integrity during switching. The quad configuration allows for multiple signal paths to be controlled within a single package.

How Many Pins does DG419DJ have and What are the Functions of the Pinout Configuration?

The DG419DJ is housed in a 16-pin plastic dual in-line package (PDIP). The pinout configuration includes:

  • V+, V-: Positive and negative power supply pins.
  • COM1-4: Common terminal for each switch channel.
  • NO1-4: Normally open terminals for each switch channel.
  • NC1-4: Normally closed terminals for each switch channel.

What are the Pros and Cons of DG419DJ?

Pros:

  • Precision Switching: Provides high precision and low distortion for accurate signal routing.
  • Quad Configuration: Allows for multiple signal paths to be controlled within a single package.
  • Low Charge Injection: Minimizes charge injection effects during switching, preserving signal integrity.
  • Low On-Resistance: Ensures minimal voltage drop across the switch for high signal fidelity.

Cons:

  • PDIP Package: The PDIP package may be larger than more modern surface-mount packages, requiring more board space.
  • External Components: May require external protection or filtering components for specific applications.

Are There Any Equivalents/Alternatives to DG419DJ for Recommendation?

  • The DG418DJ and DG420DJ from Vishay are similar quad SPST analog switches offering different performance characteristics.
  • Alternatives to the DG419DJ include the MAX4619 from Maxim Integrated and the ADG419 from Analog Devices.
