DG308ACY+

Overview

The DG308ACY+ is a quad, single-pole-single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a channel on-resistance of 60 Ω typical value and supports split supplies from ±5V to ±20V or a single positive supply from +5V to +30V. The device offers fast switching speeds with a turn-on time under 120ns and a turn-off time under 90ns. It utilizes CMOS inputs for reduced loading and low leakage currents. The component operates within a temperature range of 0°C to +70°C and is housed in a 16-pin Narrow SO package.

Feature Summary

• Monolithic, low-power CMOS design

• Single/bipolar-supply operation

Applications

• Sample-and-Hold Circuits
• Test Equipment
• Communications Systems
• PBX, PABX
• Guidance and Control Systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Confirm that the narrow SOIC variant matches the required footprint. Check current availability status as components may be subject to limited supply or end-of-life notices.

Selection Notes

Select this part for applications requiring quad SPST switching with low on-resistance. Ensure the operating voltage range aligns with the single or dual supply requirements. Verify thermal management needs based on the power dissipation limits defined in the datasheet for the selected package.

Part Context

This component belongs to the DG308A/DG309 family of quad SPST analog switches. The DG308A variant provides normally open contacts, while the DG309 provides normally closed contacts. Both share identical electrical characteristics and pin configurations, differing only in their default state.

Replacement Considerations

Direct replacements include other DG308A variants such as DG308ACJ or DG308ACK, provided the package and temperature range are compatible.
