LM393A, LM393B SMD Dual Comparators IC. || LM393 SMD Dual Comparators IC

The LM393B and LM2903B devices are the next generation versions of the industry-standard LM393 and LM2903 comparator family. These next generation B-version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2 kV ESD performance and input ruggedness through dedicated ESD clamps. The LM393B and LM2903B can drop-in replace the LM293, LM393 and LM2903, for both "A" and "V" grades.

All devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Quiescent current is independent of the supply voltage.

 Features :

• Maximum rating: up to 38 V – ESD rating (HBM): 2k V
• Low input offset: 0.37 mV
• Low input bias current: 3.5 nA
• Low supply-current: 200 µA per comparator
• Faster response time of 1 µsec
• Extended temperature range for LM393B
• Available in tiny 2 x 2mm WSON package
• B-version is drop-in replacement for LM293, LM393 and LM2903, A and V versions
•  Common-mode input voltage range includes ground
•  Differential input voltage range equal to maximum rated supply voltage: ±38 V
