Overview
The DG411DY+T is a precision monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features four independent switches in a 16-pin SOIC package, designed for high-speed signal routing with low error and distortion. The device supports single or dual power supplies ranging from 10 V to 30 V single-ended or ±4.5 V to ±20 V split supplies. Key electrical parameters include a maximum on-resistance of 45 Ohms, a maximum turn-on time of 175 ns, and a maximum turn-off time of 145 ns. It operates within a temperature range of -40°C to +85°C and draws a maximum supply current of 1 µA.
Feature Summary
- Provides four independent SPST analog switches with TTL and CMOS compatible digital inputs.
- Features break-before-make switching action to prevent signal shorting during transitions.
- Utilizes high-voltage silicon-gate process with an epitaxial layer to prevent latch-up.
- Supports wide dynamic voltage ranges with low signal errors and distortion.
Applications
- Precision automatic test equipment
- Data acquisition systems
- Communication systems
- Battery-powered systems
Procurement Notes
Verify the manufacturer designation as Analog Devices Inc. or Maxim Integrated when sourcing this component. Confirm the suffix +T indicates tape-and-reel packaging and RoHS compliance. Ensure the SOIC-16 package dimensions match the design footprint. Check for lead-free status if required by specific environmental regulations.
Selection Notes
Select the DG411DY+T for applications requiring precise analog signal switching with low on-resistance and fast transition times. Compare against the DG412 series if inverted logic control is preferred, as both share similar electrical characteristics but differ in selection logic polarity. Ensure the operating voltage range aligns with the system's single or dual supply capabilities.
Part Context
The DG411 series serves as a drop-in replacement for older DG211 and DG212 devices, offering improved performance through a high-voltage silicon-gate process. This technology reduces charge injection and prevents latch-up, making it suitable for demanding analog switching environments. The part belongs to the broader family of precision monolithic CMOS analog switches designed for industrial and commercial applications.
Replacement Considerations
The DG412 series is functionally identical regarding electrical performance but utilizes inverted selection logic. Verify logic compatibility before substituting. No other direct cross-model replacements are confirmed in the provided documentation.
