Overview
The DG412CY+T is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 10 V to 30 V for single supplies or ±4.5 V to ±20 V for dual supplies. The device features a maximum on-resistance of 80 Ohms and supports a continuous DC switch current of 30 mA. Switching performance includes a maximum turn-on time of 175 ns and a maximum turn-off time of 145 ns. It functions reliably across an extended temperature range from -40°C to +85°C and is housed in a 16-pin Narrow SOIC package.
Feature Summary
- Quad SPST configuration providing four independent signal paths
- Low power consumption with minimal supply current requirements
- High electrostatic discharge tolerance ensuring robust protection
- Guaranteed low charge injection for accurate signal integrity
Applications
- Data acquisition systems requiring precise signal routing
- Industrial process control instrumentation
- Medical equipment signal conditioning circuits
- Automotive electronic testing modules
Procurement Notes
Verify the specific suffix 'CY' against official documentation to confirm the commercial grade temperature rating and package variant. Ensure the '+T' designation aligns with the required reel packaging format for surface mount assembly processes. Cross-reference the manufacturer part number directly with Analog Devices records to validate authenticity and current production status before finalizing procurement orders.
Selection Notes
Select this component when a quad SPST topology is required for moderate-speed signal switching applications. The 80 Ohm on-resistance specification suits general-purpose analog signal paths where high precision is not critical. Verify that the 16-pin Narrow SOIC footprint matches the target PCB layout constraints and thermal management requirements for the intended operating environment.
Part Context
This device belongs to the DG411/DG412/DG413 family of improved CMOS analog switches. These components share a redesigned architecture offering enhanced on-resistance matching and flatness compared to earlier generations. The DG412 specifically provides normally open contacts, distinguishing it from the NC DG411 and mixed-contact DG413 variants within the same series.
Replacement Considerations
The DG412DY+T serves as a verified alternative within the same product family, offering identical electrical characteristics but utilizing a standard SOIC-16 package instead of the Narrow SOIC variant found in the DG412CY+T.
