Overview
The DG304ACWE is a dual single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 10V to 30V for single-supply configurations, or ±5V to ±18V for dual-supply setups. The device features a maximum on-resistance of 50 Ohms and supports a continuous DC switch current of 30 mA. Key switching parameters include a maximum turn-on time of 250 ns and a maximum turn-off time of 150 ns. It is housed in a 14-pin SOIC package and functions within an operating temperature range of 0°C to +70°C.
Feature Summary
- TTL and CMOS logic compatible control inputs simplify interface with standard digital logic families.
- Low power consumption characteristics suitable for battery-operated applications.
- High input isolation and low leakage current ensure signal integrity when switches are off.
Applications
- Signal routing in data acquisition systems
- Sample-and-hold circuits
- Program gain amplifiers
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical tolerances. Ensure the component meets RoHS requirements if applicable to the target assembly. Cross-reference the datasheet revision date to validate parameter accuracy before integration into final designs.
Selection Notes
Select this component when dual independent SPST switching is required with TTL-compatible logic levels. Verify that the 50 Ohm on-resistance and 30 mA current handling meet the load requirements. Confirm that the 14-pin SOIC package fits the available PCB footprint and thermal constraints.
Part Context
This part belongs to the DG304 series of dual SPST analog switches. It shares functional similarities with other devices in the family but differs in package configuration and specific electrical ratings. The ACWE variant denotes a specific industrial temperature range and wide-body SOIC packaging distinct from DIP or tape-and-reel options.
Replacement Considerations
Direct substitutes may include other DG304 variants with different packages, such as DG304ACJ+. Verify pin-to-pin compatibility and ensure that on-resistance and supply voltage limits match the original design specifications.
