詳細說明

The DG444 and DG445 monolithic CMOS analog switches are drop-in replacements for the popular DG211 and DG212 series devices. They include four independent single pole single throw (SPST) analog switches and TTL and CMOS compatible digital inputs. These switches feature lower analog ON resistance (<85Ω) and faster switch time (tON <250ns) compared to the DG211 and DG212. Charge injection has been reduced, simplifying sample and hold applications.Features • ON Resistance (Max). . . . . . . . . . . . . . . . . . . . . . . . . 85Ω • Low Power Consumption (PD) . . . . . . . . . . . . . . . <35μW • Fast Switching Action - tON (Max) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 250ns - tOFF (Max, DG444) . . . . . . . . . . . . . . . . . . . . . . . 140ns • Low Charge Injection • Upgrade from DG211, DG212 • TTL, CMOS Compatible • Single or Split Supply Operation • Pb-Free Plus Anneal Available (RoHS Compliant)Applications • Audio Switching • Battery Operated Systems • Data Acquisition • Hi-Rel Systems • Sample and Hold Circuits • Communication Systems • Automatic Test Equipment

常見問題解答

What is DG445DY+?

The DG445DY+ is a quad SPST (Single-Pole, Single-Throw) precision analog switch designed by Vishay Siliconix. It is commonly used in applications requiring low distortion, low leakage, and high isolation for signal switching.

How Does DG445DY+ Work?

The DG445DY+ operates as a precision analog switch that allows or blocks the flow of analog signals based on the control inputs. It features low on-resistance and low leakage current, ensuring minimal signal distortion and accurate signal routing. The switch provides high isolation between the input and output channels, making it suitable for signal integrity-sensitive applications.

How Many Pins does DG445DY+ have and What are the Functions of the Pinout Configuration?

The DG445DY+ is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • V+: Positive power supply pin.
  • V-: Negative power supply pin.
  • IN1 to IN4: Analog signal input pins for each switch channel.
  • COM1 to COM4: Common connection pins for the corresponding switch channels.
  • NO1 to NO4: Normally open output pins for each switch channel.
  • NC1 to NC4: Normally closed output pins for each switch channel.
  • EN1 to EN4: Enable control pins for each switch channel.

What are the Pros and Cons of DG445DY+?

Pros:

  • Precision Switching: Offers low on-resistance and low distortion for accurate signal routing.
  • High Isolation: Provides high isolation between channels for improved signal integrity.
  • Low Leakage: Ensures minimal leakage current for precise signal control.
  • Quad Configuration: Features four independent switch channels in a single package for space efficiency.
  • Wide Supply Voltage Range: Supports a wide range of supply voltages for versatile applications.

Cons:

  • Complex Control: Requires careful consideration of control logic for proper switch operation.
  • Cost: Precision analog switches like the DG445DY+ may have a higher cost compared to basic switch alternatives.
  • Package Size: The 16-pin SOIC package may require specialized PCB design for proper layout and heat dissipation.

Are There Any Equivalents/Alternatives to DG445DY+ for Recommendation?

  • An equivalent part to the DG445DY+ is the ADG442 from Analog Devices.
  • Alternatives to the DG445DY+ include the MAX147 from Maxim Integrated and the 74HC4066 from NXP Semiconductors.
