1 / 55 page ![]() LM393B, LM2903B, LM193, LM293, LM393 and LM2903 Dual Comparators 1 Features • NEW LM393B and LM2903B • Improved specifications of B-version – 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 • Low output saturation voltage • Output compatible with TTL, MOS, and CMOS 2 Applications • Vacuum robot • Single phase UPS • Server PSU • Cordless power tool • Wireless Infrastructure • Applicances • Building Automation • Factory automation & control • Motor drives • Infotainment & cluster 3 Description 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 provide outstanding value for cost-sensitive applications featuring 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, and the outputs can be connected to other open-collector outputs to achieve wired-AND relationships.
