LM2903QDRQ1 Descrição geral
The LM2903B-Q1 device is the next generation version of the industry-standard LM2903-Q1 comparator family. This next generation family provides outstanding value for cost-sensitive applications, with features including lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2kV ESD performance with drop-in replacement convenience.
All devices consist of two independent voltage comparators that are designed to operate over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is within 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. The outputs can be connected to other open-collector outputs.
The LM2903-Q1 and LM2903B-Q1 are qualified for the AEC-Q100 Grade 1 temperature range of -40°C to +125°C. The LM2903E-Q1 is Qualified for the Grade 0 extended temperature range of -40°C to +150°C.
