Overview
The LM393APS is a dual differential comparator manufactured by Texas Instruments, designed for single or split power supply operation. It features two independent precision voltage comparators with an input offset voltage as low as 2.0 mV. The device operates within a wide supply voltage range of 2.0 V to 36 V (single) or ±1.0 V to ±18 V (dual). Key electrical parameters include a typical supply current drain of 0.4 mA per comparator, low input bias current of 25 nA, and low input offset current of 5 nA. The output saturation voltage is low, allowing direct interface with TTL, DTL, ECL, MOS, and CMOS logic systems. The component is characterized for operation from 0°C to +70°C.
Feature Summary
- Dual independent precision voltage comparators optimized for single-supply operation
- Wide common-mode input voltage range that includes ground level
- Low power supply current drain independent of supply voltage magnitude
- Open-collector outputs compatible with various logic families including TTL and CMOS
Applications
- Limit comparators and simple analog-to-digital converters
- Pulse, squarewave, and time delay generators
- Wide range voltage-controlled oscillators (VCO)
- MOS clock timers and multivibrators
- High voltage digital logic gates
Procurement Notes
Verify the specific suffix 'APS' against the manufacturer's official datasheet to confirm package type and temperature rating. Ensure compatibility with required operating conditions and logic levels before integration. Cross-reference ordering information with authorized distributors to confirm availability and authenticity.
Selection Notes
Select this component when low power consumption and ground-referenced input sensing are required in single-supply applications. The wide supply voltage range and logic compatibility make it suitable for interfacing with various digital systems. Consider the open-collector output requirement for external pull-up resistors when designing the circuit.
Part Context
The LM393 series consists of dual independent precision voltage comparators designed specifically for single power supply operation over a wide range of voltages. These devices offer low supply current drain and low input offset voltage, making them ideal for applications requiring high precision and low power consumption. The series is widely used in consumer, automotive, and industrial electronics.
Replacement Considerations
LM2903: Industrial grade version with extended temperature range (-40°C to +85°C). LM193: Military grade version with wider temperature range (-55°C to +125°C). TLV1701: Rail-to-rail input/output alternative.
