Overview
The DG442CEE is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 10 V to 30 V for single supplies or ±4.5 V to ±20 V for dual supplies. The device features a maximum on-resistance of 85 Ohms and supports a continuous DC switch current of 30 mA. Switching times are specified with a maximum turn-on time of 250 ns and a maximum turn-off time of 170 ns. It is housed in a TQFN-16 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent SPST analog switches in a compact configuration
- Supports both single and dual power supply architectures
- Provides high-speed signal switching capabilities
Applications
- Signal routing in data acquisition systems
- Multiplexing applications in instrumentation
- Audio signal path switching
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and thermal characteristics. Ensure the component meets RoHS requirements if applicable to your assembly process. Cross-reference the datasheet revision date to validate electrical parameters before finalizing procurement specifications.
Selection Notes
Select this component when a quad SPST configuration is required with moderate on-resistance levels. Verify that the 85 Ohm maximum on-resistance aligns with your signal integrity requirements. Confirm that the TQFN-16 package dimensions fit within your PCB layout constraints and thermal management strategy.
Part Context
This part belongs to the DG442 series of improved quad SPST analog switches. It serves as a solid-state alternative to mechanical relays, offering faster switching speeds and longer operational life. The series is designed for general-purpose analog signal switching in industrial and consumer electronics.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement maintains the same channel count, package type, and electrical specifications such as on-resistance and supply voltage ranges.
