Overview
The LM293AMX is a dual analog comparator manufactured by onsemi, housed in an SOIC-8 surface-mount package. It features two independent channels with open-collector outputs and a response time of 1.4 µs. The device operates within a supply voltage range of 2 V to 36 V, drawing a typical operating current of 1 mA. Key electrical parameters include a maximum input offset voltage of 5 mV and an input bias current of 250 nA. It supports a power dissipation of 480 mW and functions within a temperature range of -25°C to +85°C.
Feature Summary
- Dual-channel architecture providing two independent precision comparators for signal processing.
- Open-collector output configuration enabling direct compatibility with TTL, DTL, ECL, MOS, and CMOS logic families.
- Wide single-supply or split power supply operation capability across the specified voltage range.
Applications
- Voltage monitoring systems
- Battery management circuits
- Motor control applications
Procurement Notes
Verify component authenticity through authorized distribution channels due to discontinuation status. Confirm RoHS compliance details as indicated in official documentation. Ensure packaging specifications match project requirements, noting availability in reel, cut tape, or MouseReel formats. Validate thermal performance against system constraints given the 480 mW power dissipation limit.
Selection Notes
Select this component for designs requiring low-power dual comparison with open-collector outputs. Consider the 1.4 µs response time and 5 mV offset voltage for precision requirements. Evaluate the SOIC-8 footprint for PCB layout compatibility. Verify that the -25°C to +85°C operating range meets environmental conditions.
Part Context
This part belongs to the LMx93/LM2903 series of low-voltage comparators. It is functionally similar to the LM293AM but distinguished by its specific suffix indicating tape-and-reel packaging. The device is designed for general-purpose comparison tasks in industrial and consumer electronics.
Replacement Considerations
The LM393B and LM2903B are confirmed next-generation B-version devices that can directly replace the LM293 series.
