Overview
The DG412DY+T is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features four independent channels in a 16-pin SOIC package. The device supports single or dual power supplies, operating within a voltage range of 10 V to 30 V for single supply and ±4.5 V to ±20 V for dual supply configurations. Key electrical specifications include a maximum on-resistance of 45 Ohms, a maximum power dissipation of 696 mW, and a maximum supply current of 1 uA. Switching performance is characterized by a maximum turn-on time of 175 ns and a maximum turn-off time of 145 ns. The component operates reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Integrates four independent SPST analog switches within a single integrated circuit.
- Supports both single-supply and dual-supply operation modes for flexible system integration.
- Features low supply current consumption suitable for power-sensitive applications.
Applications
- Signal routing in data acquisition systems
- Multiplexing sensor inputs
- Audio signal switching
Procurement Notes
Verify the specific suffix designation when ordering, as the 'T' indicates tape-and-reel packaging while other suffixes may denote tube packaging. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure that the selected package variant matches the intended PCB layout requirements. Cross-reference the full part number with authorized distributors to confirm current availability and manufacturing status.
Selection Notes
Select this component when a compact solution for multiple independent analog signal paths is required. The 16-pin SOIC package offers a balance between pin count and board space efficiency. Consider the 45 Ohm on-resistance limit when designing for low-voltage signal integrity. Verify that the supply voltage constraints align with the target system's power rails before finalizing the design.
Part Context
The DG412 belongs to the DG412 series of improved quad SPST analog switches. It is part of the broader portfolio of CMOS analog switches produced by Maxim Integrated, now part of Analog Devices. This series is designed to provide reliable switching capabilities for general-purpose analog signal handling in industrial and consumer electronics.
Replacement Considerations
Consult official substitution guides for compatible alternatives. The DG411 and DG413 are functionally related devices within the same family but may differ in channel configuration or electrical characteristics. Verify pinout compatibility and parameter alignment before implementing any substitute component.
