DG412CJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412CJ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally open (NO) configuration and operates within a temperature range of 0°C to +70°C in a 16-pin Plastic DIP package. The device supports single supplies from +10V to +30V or bipolar supplies from ±4.5V to ±20V. Key electrical parameters include a maximum on-resistance of 45Ω, an on-resistance match between channels of 3Ω max, and guaranteed on-resistance flatness of ∆4Ω max over the signal range. Charge injection is limited to 10pC max, with off-leakage current below 5nA at +85°C. Switching times are specified as 175ns max for turn-on and 145ns max for turn-off.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides low on-resistance matching between switches and guaranteed on-resistance flatness over the signal range.
• Features improved charge injection and lower off-leakage current over temperature compared to previous generations.
• Supports rail-to-rail signal handling and is compatible with TTL/CMOS logic inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CJ' corresponds to the 16-pin Plastic DIP package and the 0°C to +70°C operating temperature range. Confirm that the component meets RoHS compliance requirements if applicable to the project specifications. Ensure the supply voltage limits align with the system design constraints before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally open SPST configuration is required for signal routing. The 45Ω on-resistance and 10pC charge injection make it suitable for general-purpose analog switching applications. Consider the 16-pin DIP package for through-hole mounting requirements and verify that the 0°C to +70°C temperature range fits the environmental conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG412CJ belongs to the Maxim redesigned DG411/DG412/DG413 series of improved, quad, SPST analog switches. This family offers plug-in upgrades for industry-standard switches with enhanced performance characteristics such as lower power consumption and higher ESD tolerance. The DG412 variant specifically provides the normally open function within this lineup.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411CJ and DG413CJ are direct pin-compatible replacements within the same series, differing only in their normally closed or mixed NO/NC configurations respectively. Verify that the functional logic sense matches the circuit design requirements when substituting these parts.
