DG412FDY+

Overview

The DG412FDY+ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features fault protection for inputs and rail-to-rail signal handling capability. All terminals are protected from overvoltage faults up to ±36V with power on and up to ±40V with power off. The device operates with dual power supplies ranging from ±4.5V to ±20V or a single supply between +9V and +36V. On-resistance is 35Ω maximum at +25°C and is matched between switches to 1.5Ω maximum. Digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL and CMOS logic compatibility when using ±15V or a single +12V supply.

Feature Summary

Fault-protected inputs and rail-to-rail signal handling capability
All switches turn off when power is removed
Pin compatible with industry-standard non-protected DG411/DG412/DG413

Applications

Communication Systems
Signal Routing
Test Equipment
Data Acquisition
Industrial and Process Control Systems

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the package type matches the SOIC-16 specification and check the RoHS compliance status as indicated in the ordering information. Ensure the operating temperature range meets the requirements of the specific application environment before finalizing procurement decisions.

Selection Notes

Select this component when fault protection and rail-to-rail signal handling are required in a compact surface-mount package. It serves as a direct pin-compatible replacement for standard DG411/DG412/DG413 switches without requiring PCB layout changes. Consider the ±36V fault protection limits and the specific supply voltage requirements when designing the circuit.

Part Context

The DG412F belongs to the DG411F/DG412F/DG413F family of quad SPST analog switches. While the DG411F features four normally closed switches and the DG413F has two NC and two NO switches, the DG412F specifically contains four normally open switches. This family shares identical pinouts and core fault-protection architecture.
