DG183AP/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG183AP/883 is a precision dual double-pole, single-throw (DPST) analog switch manufactured by Vishay Siliconix. It utilizes four n-channel JFET transistors and a TTL-compatible bipolar driver to provide accurate switching of video and audio signals with constant on-resistance over the entire analog range. The device operates within an extended temperature range of -55°C to +125°C and features low leakage current below 2 nA. Key electrical parameters include a maximum drain-source on-resistance of 10 ohms, a saturation drain current of 200 mA, and a power dissipation rating of 900 mW in its 16-pin sidebraze package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the component meets the specific military qualification standards associated with the /883 suffix. Confirm the physical package type matches the required 16-pin sidebraze configuration. Ensure the operating temperature range aligns with the -55°C to +125°C specification. Validate the on-resistance requirements against the 10 ohm maximum limit. Check for compliance with relevant radiation hardness criteria if applicable.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual DPST configuration with exceptionally low on-resistance is required. The DG183 variant is specifically chosen over the DG184 or DG185 models due to its lower resistance profile. Consider the high current capability of 200 mA for demanding load conditions. Evaluate the need for TTL compatibility and the specific supply voltage configurations provided in the datasheet.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG183/184/185 series of high-speed drivers and dual DPST JFET switches. The series is designed for applications requiring flat on-resistance characteristics. The DG183 represents the lowest resistance option within the family, offering 10 ohms compared to higher values in other variants. All models share similar architectural features but differ primarily in their on-resistance specifications.
