DG309DJ

Overview

The DG309DJ is a quad, single-pole-single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features normally closed contacts with a typical on-resistance of 60 Ω and a maximum of 100 Ω. The device supports split supplies from ±5V to ±20V or a single positive supply from +5V to +30V. Key electrical parameters include a turn-on time under 120ns, a turn-off time under 90ns, and charge injection of -10 pC. It operates within an extended temperature range of -40°C to +85°C and is housed in a 16-pin narrow SOIC package.

Feature Summary

CMOS logic compatible inputs for reduced loading
Monolithic low-power CMOS design
High breakdown voltage rating for signal blocking

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the package type and temperature grade. Confirm current availability status directly with authorized distributors as component lifecycle states may change. Ensure the selected variant matches the required operating conditions for the target application environment.

Selection Notes

Select the DG309DJ when a normally closed SPST configuration is required for signal routing. Verify that the 60 Ω on-resistance meets the circuit's impedance requirements. Ensure the power supply rails fall within the specified operational limits to maintain performance characteristics such as switching speed and leakage current specifications.

Part Context

This component belongs to the DG308A/DG309 family of quad SPST analog switches. While the DG308A offers normally open contacts, the DG309 provides normally closed functionality. Both share identical pinouts and electrical characteristics, allowing for flexible design choices based on the desired default state of the analog signal path.
