Overview
The LM339ADRG4 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 36V. The device features four independent comparators with open-collector outputs capable of sinking up to 20mA. Key electrical specifications include a maximum input offset voltage of 3mV and a typical quiescent current of 800µA. The component supports an operating temperature range from 0°C to 70°C and complies with RoHS standards.
Feature Summary
- Integrates four independent high-gain differential comparators within a single integrated circuit
- Features open-collector outputs compatible with various logic families including TTL and CMOS
- Designed for operation from a single power supply across a wide voltage range
- Provides low power consumption suitable for battery-operated applications
Applications
- Temperature sensing circuits using thermistors or RTDs
- Level detection for analog signal monitoring
- Peak hold circuits for waveform processing
- Supervisory threshold monitoring systems
Procurement Notes
Verify the specific suffix 'ADR' confirms the tape and reel packaging format and industrial temperature grade. Ensure the datasheet revision matches the design requirements for input offset voltage and propagation delay characteristics. Confirm RoHS compliance status for the specific manufacturing lot to meet environmental regulations.
Selection Notes
Select this component when multiple independent comparison functions are required in a compact surface-mount footprint. Consider the open-collector output structure for interfacing with different voltage domains. Evaluate the 3mV input offset voltage specification against the precision requirements of the application signals.
Part Context
This part belongs to the LM339 family of quad comparators, widely used in general-purpose analog switching applications. It serves as a standard solution for single-supply comparator tasks where low cost and moderate precision are prioritized over high-speed performance.
Replacement Considerations
LM339DRG4: Pin-compatible alternative with similar electrical characteristics but potentially different packaging quantities.
FAQ
What is the output configuration of the LM339ADRG4?
The outputs are open-collector type, requiring an external pull-up resistor to the desired logic voltage level.
Does the LM339ADRG4 support dual power supplies?
While primarily designed for single-supply operation, it can function with split supplies provided the common-mode input voltage range is respected.
