DG181AA/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG181AA/883 is a dual single-pole, single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features two independent switches with a maximum on-resistance of 30 ohms and an analog signal range spanning from -7.5 V to +15 V. The device operates within a temperature range of -55°C to +125°C and utilizes a 10-pin metal can package. Key electrical parameters include a source off leakage current of 1 nA at room temperature and up to 100 nA at high temperatures, alongside a drain off leakage current of 1 nA at room temperature and 100 nA at high temperatures.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the component matches the specific military-grade suffix /883 requirements. Confirm the package type corresponds to the 10-pin metal can variant. Ensure the operating temperature range aligns with the specified -55°C to +125°C limits. Check for compliance with relevant military standards associated with this part number.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG181AA/883 when a 30-ohm on-resistance is required for dual SPST switching. Consider this part for environments demanding extended temperature operation from -55°C to +125°C. Evaluate the 10-pin metal can package for suitable mechanical integration. Compare against DG180 or DG182 variants if different resistance values are needed.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG180/181/182 series of high-speed JFET analog switches. The series is designed for precision applications requiring flat on-resistance characteristics. The DG181 variant specifically targets circuits needing a 30-ohm on-resistance profile. The /883 suffix indicates a military-grade qualification standard.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG180AA/883 offers a lower 10-ohm on-resistance. DG182AA/883 provides a higher 75-ohm on-resistance. Both share the same package and general functionality but differ in resistance specifications.
