Overview
The DG412DY+ is a monolithic CMOS analog switch IC featuring four independent single-pole single-throw (SPST) channels. It operates with a maximum on-resistance of 45 Ohms and supports dual supply voltages ranging from ±4.5V to ±20V, or a single supply from 10V to 30V. The device exhibits a maximum turn-on time of 175ns and a turn-off time of 145ns. It functions within an operating temperature range of -40°C to +85°C and is housed in a 16-pin SOIC package.
Feature Summary
- Four independent SPST analog switches integrated into a single monolithic CMOS structure
- TTL and CMOS compatible digital input logic for simplified interface control
- Epitaxial layer design prevents latch-up associated with older CMOS technologies
Applications
- Sample and hold circuits requiring reduced charge injection
- High impedance sensing applications utilizing low leakage current
- Data acquisition systems managing AC or bidirectional signals
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm exact packaging and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with authorized distributors to confirm current availability status and lead times.
Selection Notes
Select this component when four isolated analog switching paths are required within a compact surface-mount footprint. Consider the 45 Ohm on-resistance limit and ±20V dual supply capability as primary constraints. Verify that the 175ns switching speed aligns with system timing requirements compared to faster alternatives.
Part Context
This device belongs to the DG41x series of improved quad SPST analog switches. It serves as a drop-in replacement for legacy devices like the DG211 and DG212, offering lower on-resistance and faster switching speeds while maintaining pin compatibility. The series utilizes a high-voltage silicon-gate process for enhanced performance.

FAQ
How does the DG412 differ from the DG411?
The DG412 and DG411 switches are identical in architecture and performance but differ only in the polarity of their selection logic.
What is the maximum voltage range permitted for signal control?
The device permits controlling signals up to 40V peak-to-peak, supported by power supplies ranging from single-ended +5V to +44V or split ±5V to ±20V.
