Comparators datasheet and documents for PM139AY
Comparators Overview
The PM139AY is a quad low-power voltage comparator manufactured by Analog Devices Inc. It features four independent precision comparators with a maximum input offset voltage of 9000 µV and a response time of 1300 ns. The device utilizes a CDIP14 hermetically sealed ceramic DIP package. It operates within a temperature range of -55 °C to +125 °C, supporting single or split power supply configurations.
Comparators Feature Summary
- Four independent precision voltage comparators integrated into a single unit
- Hermetically sealed ceramic dual in-line package for environmental stability
- Low power consumption design suitable for battery-operated systems
- Input common-mode voltage range includes ground for single-supply convenience
Comparators Applications
- Precision voltage monitoring circuits
- Battery-powered instrumentation
- Industrial control systems requiring wide temperature operation
- Signal conditioning interfaces
Comparators Procurement Notes
Verify the specific suffix 'AY' against the official Analog Devices datasheet to confirm pinout, package dimensions, and electrical tolerances. Ensure the procurement source provides documentation confirming the hermetic seal status and ceramic construction, as these are critical for the specified military-grade operating temperature range.
Comparators Selection Notes
Select this component when high reliability and hermetic sealing are required alongside quad comparator functionality. The wide operating temperature range makes it suitable for harsh environments where standard plastic packages may fail. Verify that the 1300 ns response time meets the system's speed requirements.
Comparators Part Context
The PM-139 series consists of quad low-power voltage comparators designed for precision applications. The PM139AY variant specifically denotes the hermetically sealed ceramic DIP version, distinguishing it from non-hermetic plastic equivalents. This family offers low offset voltage and bias current, facilitating accurate signal comparison in single-supply systems.
Comparators Replacement Considerations
Cross-reference with other hermetically sealed quad comparators from Analog Devices or qualified alternatives. Ensure substitute parts match the CDIP14 footprint and meet the -55 °C to +125 °C operating temperature specification.
