DG308ACK

Overview

The DG308ACK is a CMOS analog switch integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features four single-pole single-throw (SPST) normally-open channels housed in a CDIP-16 narrow package designed for through-hole mounting. The device operates with a single supply voltage ranging from 5 V to 30 V or dual supplies of ±5 V to ±20 V. Key electrical specifications include a maximum on-resistance of 100 Ohms, a maximum power dissipation of 900 mW, and a maximum supply current of 10 uA. Switching performance is characterized by a maximum turn-on time of 200 ns and a turn-off time of 150 ns. The component supports a DC switch current of 20 mA and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Four independent SPST analog switching channels integrated into a single monolithic CMOS structure
• TTL and CMOS logic compatible control inputs for direct interfacing with standard digital systems
• Low power consumption capability suitable for battery-operated or energy-efficient applications

Applications

• Signal routing in data acquisition systems
• Multiplexing sensor inputs in industrial measurement equipment
• Audio signal path switching in consumer electronics

Procurement Notes

Verify the manufacturer status carefully as this component may be discontinued or subject to limited availability. Confirm that the CDIP-16 package dimensions match your PCB footprint requirements. Ensure that the 100 Ohm on-resistance meets your signal integrity specifications. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Validate that the operating temperature range covers your intended application environment.

Selection Notes

Select this component when four independent low-speed analog switches are required in a through-hole package. Compare the 100 Ohm on-resistance against other series members like the DG303A which offers lower resistance but different channel configurations. Consider the 20 mA DC switch current limit when designing load circuits. Evaluate the 900 mW power dissipation rating to ensure adequate thermal management in enclosed designs.

Part Context

The DG308ACK belongs to the DG308 family of CMOS analog switches. This family provides multiple channel configurations including quad SPST variants. The part shares core technology with other Maxim Integrated switch products but differs in pin count and channel arrangement. It serves as a discrete solution for analog signal routing before the prevalence of highly integrated multiplexer arrays.

Replacement Considerations

Publicly confirmed substitute part numbers for the DG308ACK are not available in the provided documentation. Verify compatibility with alternative quad SPST switches such as the DG308AC/D die variant or other CDIP-16 packages from the same manufacturer family.
