DG190AP/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG190AP/883 is a high-speed precision analog switch featuring dual single-pole, double-throw (SPDT) channels. It utilizes n-channel JFET transistors and a TTL-compatible bipolar driver to achieve break-before-make switching action. The device operates with a maximum on-resistance of 30 ohms at room temperature and supports an analog signal range of ±7.5 V to +15 V. It functions within a supply voltage range of -20 V to +15 V and maintains an operating temperature range from -55 °C to +125 °C. Key electrical parameters include a source off leakage current of 100 nA and a drain off leakage current of 100 nA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm military-grade compliance specifications and traceability documentation are available. Ensure proper handling procedures are followed due to the ceramic package construction. Validate that the specific ordering suffix matches the required temperature and radiation hardness ratings.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when constant on-resistance across the full analog voltage range is critical. The DG190 variant offers a 30-ohm on-resistance, balancing speed and power dissipation compared to lower resistance alternatives. Verify that the dual SPDT configuration meets the circuit topology requirements. Ensure the supply voltage limits accommodate the system's peak-to-peak signal swings.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG189/190/191 series of high-speed drivers with dual SPDT JFET switches. The series is designed for accurate switching of video and audio signals where low distortion and high bandwidth capability are necessary. The devices share identical pinouts and functional block diagrams, differing primarily in their specified on-resistance values.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG189AP/883: Lower on-resistance (10 ohms). DG191AP/883: Higher on-resistance (75 ohms). JM38510/11107BXA: Flat pack version. Verify on-resistance tolerance and package style compatibility before substitution.
