Overview
The DG412AK is a quad single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally open configuration and operates within an extended temperature range of -55°C to +125°C. The device utilizes a 16-pin CERDIP package and supports both single (+10V to +30V) and bipolar (±4.5V to ±20V) supply voltages. Key electrical parameters include a maximum on-resistance of 35Ω, a maximum on-resistance match between channels of 3Ω, and guaranteed on-resistance flatness of Δ4Ω over the signal range. Switching times are specified with a maximum turn-on time of 175ns and a maximum turn-off time of 145ns.
Feature Summary
- Features low on-resistance matching between switches and guaranteed on-resistance flatness over the signal range.
- Provides rail-to-rail signal handling capability for bidirectional conduction.
- Offers improved charge injection performance and low off-leakage current over temperature.
- Withstands electrostatic discharge up to 2000V minimum per Method 3015.7.
Applications
- Sample-and-Hold Circuits
- Communication Systems
- Test Equipment
- Battery-Operated Systems
- Audio Signal Routing
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Confirm that the component meets all required environmental standards for the intended application environment before finalizing procurement decisions.
Selection Notes
Select this component when an extended industrial or military temperature range is required alongside high reliability. Ensure the design accommodates the 16-pin CERDIP footprint and verify that the logic supply voltage aligns with TTL or CMOS requirements for proper switching control.
Part Context
This part belongs to the DG411/DG412/DG413 family of improved quad SPST analog switches. The DG412 variant specifically provides a normally open configuration, distinguishing it from the DG411 (normally closed) and DG413 (mixed NC/NO). The AK suffix denotes the ruggedized ceramic DIP package suitable for harsh environments.

FAQ
What is the default state of the switches in the DG412?
The DG412 features a normally open (NO) configuration for all four channels.
How does the DG412 handle signals in either direction?
The switches conduct equally well in either direction, supporting rail-to-rail signal handling.
What is the maximum on-resistance flatness specification?
The on-resistance flatness is guaranteed at a maximum of Δ4Ω over the entire signal range.
