Details
General Description The DG308A/DG309 are quad, single-pole-single-throw (SPST) analog switches. The DG308A is normally open (SPST, NO), while the DG309 is normally closed (SPST, NC). Both parts feature fast switching speeds and low on resistance over the analog range. Other features include a turn-on time under 120ns, a turn-off time under 90ns, and a channel on-resistance of 60Ω. CMOS inputs provide reduced input loading and very low leakage currents.Features ♦ 60Ω rDS(ON) ♦ Single/Bipolar-Supply Operation ♦ CMOS Logic Compatible ♦ Monolithic, Low-Power CMOS DesignApplications Sample-and-Hold Circuits Test Equipment Communications Systems PBX, PABX Guidance and Control Systems Heads-Up Displays Military Radios

FAQs
What is DG308ACJ?
The DG308ACJ is a precision monolithic quad SPST CMOS analog switch designed by Siliconix (a subsidiary of Vishay). It is well-suited for applications that require high precision and low distortion in switching analog signals, such as precision instrumentation, data acquisition systems, and audio signal routing.
How Does DG308ACJ Work?
The DG308ACJ operates by providing high-precision, low-distortion switching of analog signals using complementary metal-oxide-semiconductor (CMOS) technology. It features low on-resistance and low charge injection, ensuring minimal signal degradation during switching. The quad configuration allows multiple analog inputs to be selectively connected to a common output or other signal paths.
How Many Pins does DG308ACJ have and What are the Functions of the Pinout Configuration?
The DG308ACJ is housed in a 16-pin ceramic DIP (Dual Inline Package) package. The pinout configuration includes:
- V+, V-: Positive and negative power supply pins.
- VCC: Positive power supply pin for control logic.
- VSS: Ground pin for control logic.
- IN1 - IN4: Analog input pins for the four switching channels.
- COM1 - COM4: Common analog output pins for the four switching channels.
- NO1 - NO4: Normally open switch control pins for the four channels.
- NC1 - NC4: Normally closed switch control pins for the four channels.
What are the Pros and Cons of DG308ACJ?
Pros:
- Precision: Provides high precision and low distortion for switching analog signals.
- Low On-Resistance: Minimizes signal attenuation during switching.
- Quad Configuration: Allows for multiple analog inputs to be selectively connected to outputs.
- Wide Supply Voltage Range: Supports a wide range of power supply voltages.
- Temperature Stability: Maintains performance over a wide temperature range.
Cons:
- Power Consumption: May have higher power consumption compared to some low-power analog switches.
- Package Size: The 16-pin DIP package may be relatively large for compact designs.
- Complex Control: Requires careful consideration of control logic for proper switching operation.
Are There Any Equivalents/Alternatives to DG308ACJ for Recommendation?
- The ADG409 from Analog Devices is a similar quad SPST CMOS analog switch with high precision.
- Alternatives to the DG308ACJ include the MAX4660 from Maxim Integrated and the CD4066B from Texas Instruments.
