Overview
The LM339ADR is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates on a single power supply ranging from 2V to 30V. Key electrical specifications include a maximum input offset voltage of 3mV and an input bias current of 250nA. The device features open-collector outputs capable of sinking up to 6mA per channel. It functions within a commercial temperature range of 0°C to +70°C and consumes approximately 500µA of operating supply current.
Feature Summary
- Integrates four independent differential comparators within a compact surface-mount package for space-constrained designs.
- Features open-collector outputs that facilitate direct interfacing with various logic families including TTL and CMOS.
- Operates efficiently on a wide single-supply voltage range, supporting low-power applications.
Applications
- Over-voltage and under-voltage detection circuits
- Analog-to-digital conversion interfaces
- Temperature sensing systems
Procurement Notes
Verify the specific suffix 'ADR' confirms the SOIC-14 package and tape-and-reel packaging format. Ensure the component meets RoHS compliance standards required for the target assembly process. Confirm the manufacturer is Texas Instruments to guarantee original quality and traceability. Check for any specific handling requirements related to electrostatic discharge during storage and installation.
Selection Notes
Select this component when a quad comparator configuration is required in a surface-mount layout. It is suitable for applications needing open-collector outputs to drive different logic levels. Consider the 3mV offset voltage specification if precise threshold detection is necessary. Verify that the 0°C to +70°C operating temperature range aligns with the environmental conditions of the final product.
Part Context
This part belongs to the LM339 family of low-power quad comparators. It serves as a surface-mount alternative to through-hole variants like the LM339N. The device is widely used in industrial and consumer electronics where multiple comparison functions are needed in a small footprint. It complements other Texas Instruments analog signal chain components.
Replacement Considerations
Direct pin-compatible alternatives include the LM339DR and LM339ADRG4. Cross-reference datasheets to confirm identical pinouts and electrical characteristics before substitution.
