Overview
The AS339P-E1 is a low-power, low-offset voltage dual comparator manufactured by Diodes Incorporated. It features two independent precision voltage comparators designed for operation from a single power supply over a wide voltage range, with split supply operation also possible. The device offers low supply current drain that is independent of the power supply voltage magnitude. It is housed in an 8-pin DIP package and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Low input offset voltage for high precision applications
- Wide single-supply voltage range capability
- Low supply current drain independent of supply voltage
Applications
- Precision voltage monitoring circuits
- Threshold detection systems
- General-purpose analog signal comparison
Procurement Notes
Verify the package type matches the required footprint, as the model suffix 'P' typically indicates a DIP package while other variants may use SOIC or TSSOP. Confirm the specific electrical tolerances against the official datasheet, as offset voltage specifications can vary between standard and A-grade versions. Ensure the operating temperature range meets the environmental requirements of the target application.
Selection Notes
Select this component when a dual-channel comparator with low power consumption and wide supply voltage flexibility is required. Consider the AS339A variant if stricter input offset voltage specifications are necessary for the design. Evaluate the package constraints to ensure the DIP form factor fits the PCB layout, noting that surface mount alternatives exist within the same family.
Part Context
This part belongs to the AS339/339A series of low-power, low-offset voltage quad and dual comparators. The series is compatible with industry-standard 339 devices, ensuring pin-out interchangeability for many legacy designs. The product line emphasizes low supply current and wide common-mode input voltage ranges, making it suitable for battery-powered and general-purpose industrial applications.
Replacement Considerations
Check for direct pin-compatible substitutes such as the LM339 or MC339, verifying that their electrical parameters like offset voltage and supply current meet the design requirements. Ensure any replacement maintains the same output type (open collector) and package dimensions if board space is constrained.
