DG390BDJ

Overview

The Vishay DG390BDJ is a precision quad single-pole single-throw (SPST) analog switch IC manufactured by Vishay Siliconix. It features a DIP-16 package and operates with dual supplies ranging from ±15 V to ±22 V or a single supply of 30 V. The device offers low on-resistance of 8 Ω maximum, ensuring high signal integrity. Key electrical parameters include an on-resistance matching of 1 Ω, a channel-to-channel isolation of 70 dB at 1 kHz, and a leakage current of 1 nA. Operating temperatures span from -40 °C to +85 °C.

Feature Summary

Monolithic CMOS construction provides high-speed switching with low power consumption.
Precision matched on-resistance ensures minimal signal distortion across channels.
High channel-to-channel isolation prevents crosstalk in multi-channel applications.

Applications

Data acquisition systems requiring precise signal routing
Programmable gain amplifiers and instrumentation circuits
Audio signal processing and switching matrices

Procurement Notes

Verify the specific ordering suffix BDJ confirms the PDIP-16 package and commercial temperature range. Confirm RoHS compliance status through official datasheets as manufacturing standards may evolve. Cross-reference the manufacturer part number against authorized distributors to ensure authenticity and traceability before procurement.

Selection Notes

Select this component when four independent SPST switches are required in a single package. Ensure the system voltage does not exceed the absolute maximum ratings of ±22 V. Consider the 8 Ω on-resistance for voltage drop calculations in low-voltage signal paths compared to lower resistance alternatives.

Part Context

The DG390 belongs to the DG enhanced analog switch family, designed for improved performance over earlier generations. It serves as a quad SPST alternative to dual DPDT configurations like the DG390. The device integrates protection diodes and is suitable for general-purpose analog signal switching in industrial and consumer electronics.

Replacement Considerations

Direct pin-compatible substitutes within the same Vishay lineup include the DG390EBJ for SOIC-16 packaging. Other manufacturers offer functional equivalents such as the ADG390 from Analog Devices. Verify on-resistance and leakage specifications match the original design requirements when substituting.
