Overview
The DG308AC/D is a CMOS analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features four single-pole single-throw (SPST) normally-open switches within a die package. The device supports single supply voltages from 5V to 30V or dual supplies of ±5V to ±20V. Key electrical specifications include a maximum on-resistance of 100 Ohms, turn-on time of 200ns, and turn-off time of 150ns. Charge injection is specified at -10pC, with off-state leakage current up to 5nA. The component operates within a temperature range of 0°C to +70°C.
Feature Summary
- Integrates four independent SPST analog switches in a compact die format.
Applications
- Signal routing in data acquisition systems.
Procurement Notes
Verify the specific procurement status for the DG308AC/D die variant, as availability may be restricted. Confirm that the bare die form factor aligns with the target assembly process and packaging requirements. Ensure compliance with relevant environmental directives before integration into final products.
Selection Notes
Select this component when a high-density solution for multiple analog switching functions is required without the overhead of a standard integrated circuit package. Consider the thermal management capabilities of the substrate and the bonding wire integrity during design. Verify that the 100 Ohm on-resistance meets the signal path loss requirements of the application.
Part Context
This part belongs to the DG308 series of CMOS analog switches. It shares functional similarities with other devices in the family but differs in package configuration. The die version allows for custom packaging solutions, distinguishing it from pre-packaged equivalents like the DG308ACWE+.
Replacement Considerations
The DG308AC/D is listed as obsolete. Potential alternatives should be sought among current production CMOS analog switches with similar channel counts and voltage ratings.
