Analog Comparators Dual Differential

LM393B, LM2903B, LM193, LM293, LM393 and LM2903 Dual Comparators

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.
