The LM2903 from STMicroelectronics is a dual, precision voltage comparator IC designed for versatile operation. It features a wide supply voltage range, supporting single or dual supplies from 2V up to 36V. The device consumes very low supply current, approximately 0.4 mA, which is independent of the supply voltage magnitude, making it suitable for battery-powered applications.
Key electrical characteristics include a low input biasing current of 25 nA and a low input offset current of ±5 nA. The maximum offset voltage is ±3 mV. The input common-mode voltage range includes ground, and the differential input voltage range is equal to the power supply voltage. The output features an open-collector design, allowing compatibility with TTL, DTL, ECL, MOS, and CMOS logic systems, and has a low output saturation voltage of 250 mV at 4 mA.
This comparator is available in an SOIC-8 package with surface mount mounting type. It operates across a temperature range of -40°C to +125°C. The LM2903 is well-suited for applications such as limit comparators, simple analog-to-digital converters, pulse generators, and wide-range VCOs.
