Product Introduction
The LM393B and LM2903B devices are the next-generation versions of the industry-standard LM393 and LM2903 comparator families. The next-generation B-version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, and lower propagation delay, and offer improved 2kV ESD performance and input ruggedness through dedicated ESD clamps. The LM393B and LM2903B are direct replacements for the LM293, LM393, and LM2903 ("A" and "V" versions). All devices contain two independent voltage comparators that can operate from a single supply over a wide voltage range. The quiescent current is independent of the supply voltage.
Features
- Maximum rating: up to 38V
- ESD rating (HBM): 2kV
- Low input offset voltage: 0.37mV
- Low input bias current: 3.5nA
- Low supply current: 200μA per comparator
- Faster response time (1 microsecond)
- 2×2mm miniature WSON package
- B version directly replaces A and V versions of LM293, LM393, and LM2903
- Common-mode input voltage range includes ground
- Differential input voltage range equals maximum rated supply voltage: ±38V
- Low output saturation voltage
- Output compatible with TTL, MOS, and CMOS
Applications
- - Robotic vacuum cleaners - Single-phase UPS - Server PSU - Cordless power tools - Wireless infrastructure - Appliances - Building automation - Factory automation & control - Motor drives - Infotainment systems & instrument clusters
