DG181AA

Overview

The DG181AA is a precision dual single-pole, single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features two independent channels with a maximum on-resistance of 30 ohms and an operating temperature range from -55°C to +125°C. The device utilizes n-channel JFET transistors and a TTL-compatible bipolar driver for fast switching. Key electrical parameters include a typical source off leakage current of 0.05 nA at room temperature and a drain off leakage current of 0.04 nA. Switching times are specified with a maximum turn-on time of 150 ns and a maximum turn-off time of 130 ns.

Feature Summary

Provides constant on-resistance over the entire analog signal range
Features low leakage current and low crosstalk characteristics
Includes fault protection capabilities for high voltage blocking
Designed for high precision applications requiring low distortion

Applications

Audio switching circuits
Video signal routing
Sample-and-hold systems
Data acquisition front ends

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'AA' corresponds to the required military-grade temperature range (-55°C to +125°C). Check for RoHS compliance status as indicated in official documentation. Validate package integrity upon receipt to ensure no damage to the metal can housing.

Selection Notes

Select this component when a 30-ohm on-resistance is required for SPST switching applications. Ensure the design supports dual supply voltages up to ±15V. Verify that the TTL-compatible logic levels match the system control interface. Consider the TO-100-10 metal can package constraints for thermal management and physical footprint.

Part Context

This part belongs to the DG180/181/182 series of high-speed drivers with dual SPST JFET switches. The DG181 variant specifically offers a 30-ohm on-resistance, distinguishing it from the 10-ohm DG180 and 75-ohm DG182 models. All variants share similar architectural features including low leakage and high bandwidth capabilities.
