Overview
The DG412CJ+ is a quad single-pole/single-throw (SPST) analog switch fabricated using a 44V silicon-gate process. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. The device features a maximum on-resistance of 35Ω, with an improved on-resistance match between channels of 3Ω max and guaranteed flatness of Δ4Ω max over the signal range. It guarantees low charge injection of 10pC max and off-leakage current less than 5nA at +85°C. Switching times are less than 150ns for turn-on and 100ns for turn-off. The component provides an ESD tolerance of 2000V minimum per Method 3015.7 and operates within a temperature range of 0°C to +70°C in a 16-pin Plastic DIP package.
Feature Summary
- Quad SPST configuration with TTL/CMOS-compatible logic inputs
- Low power consumption with rail-to-rail signal handling capabilities
- High electrostatic discharge protection rated at 2000V minimum
Applications
- Sample-and-Hold Circuits
- Communication Systems
- Test Equipment
- Battery-Operated Systems
- Audio Signal Routing
Procurement Notes
Verify the specific suffix 'CJ' corresponds to the 0°C to +70°C operating temperature range and the 16-pin Plastic DIP package format. Confirm that the '+T' designation indicating tape and reel packaging is not required if bulk tube delivery is intended. Ensure the ordering part number matches the exact manufacturer specifications for lead-free compliance and RoHS status before finalizing procurement orders.
Selection Notes
Select the DG412CJ+ when normally open (NO) switch logic is required, as opposed to the normally closed DG411. Consider the DG413 variant if mixed NC and NO switches are needed for break-before-make applications. Verify that the 35Ω on-resistance meets system requirements compared to lower resistance alternatives. Ensure the bipolar or single supply voltage ranges align with the application's power constraints.
Part Context
The DG412CJ+ belongs to the redesigned DG411/DG412/DG413 series of monolithic CMOS analog switches. This family serves as a plug-in upgrade for industry-standard devices, offering improved on-resistance matching and lower leakage currents. The DG412 specifically provides four independent normally open switches, distinguishing it from the DG411's normally closed configuration and the DG413's mixed logic arrangement.
Replacement Considerations
The DG412CJ+ is designed as a drop-in replacement for the legacy DG212 series devices. Designers upgrading from older CMOS technologies should verify that the latch-up immunity provided by the epitaxial layer in the new design meets reliability standards.
