DG412CY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412CY+ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. The device features a maximum on-resistance of 45Ω and an on-resistance flatness of 4Ω over the signal range. Turn-on time is 175ns maximum, while turn-off time is 145ns maximum. It provides low charge injection of 10pC maximum and withstands electrostatic discharge of 2000V minimum per Method 3015.7. The component is housed in a 16-pin Narrow SO package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status through the datasheet before procurement. Ensure logic voltage levels match system requirements for proper TTL/CMOS compatibility.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required for analog signal routing. Verify that the 45Ω on-resistance meets circuit impedance requirements. Check if the 0°C to +70°C commercial temperature range aligns with the application environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411/DG412/DG413 family of improved analog switches. The DG412 variant specifically utilizes normally open (NO) logic. These devices are fabricated using a silicon-gate process designed for low power consumption and high reliability.
