Overview
The DG185AP is a precision dual double-pole, single-throw (DPST) analog switch manufactured by Harris Corporation. It features two independent switching functions housed in a CDFP14 ceramic flat package with 14 pins. The device operates within an extended temperature range from -55 °C to 125 °C. Key electrical characteristics include separate outputs and a normally open configuration. The component is designed for high-precision signal routing applications requiring constant on-resistance over the entire analog range.
Feature Summary
- Provides precise switching of video and audio signals
- Maintains constant on-resistance across the full analog input range
- Features break-before-make switching logic to prevent channel shorting
Applications
- Audio signal routing and switching
- Precision video switching systems
- Sample-and-hold circuits
- Aerospace instrumentation
Procurement Notes
Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Analog Devices. Confirm whether the specific unit is a legacy Harris part or an ADI continuation. Check for lead-free compliance status, as original specifications may indicate non-RoHS materials depending on the production era.
Selection Notes
Select this component when dual DPST switching with low leakage and crosstalk is required. Ensure the operating environment supports the specified -55 °C to 125 °C temperature range. Verify that the CDFP14 ceramic package dimensions fit the target PCB layout and that the supply voltage levels match the switch control requirements.
Part Context
This device belongs to the DG183/184/185 series of precision analog switches. These components are engineered for applications demanding high accuracy and isolation. The series is particularly noted for its suitability in aerospace and military-grade equipment where reliability and signal integrity under extreme conditions are critical.
Replacement Considerations
Check for equivalents within the Analog Devices portfolio following the acquisition of Harris Semiconductor assets. Verify pin compatibility and functional equivalence before substitution.
