STMicroelectronics LM2903B
The LM2903B consists of two independent low-power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. It is fully specified at 5 V and 36 V supply voltage operation, however operation from dual power supplies is also possible. The B-grade version of the LM2903 comparators offers an increased maximum operating voltage of 40 V and improved electrical characteristics.FEATURES
● Wide single supply voltage range or dual supplies +2 V to +36 V or ±1 V to ±18 V● Very low supply current 0.5 mA typ., essentially independent of supply voltage
● Low input bias current: 20 nA typ.
● Low input offset current: ±5 nA typ.
● Input common-mode voltage range includes negative rail
● Low output saturation voltage: 250 mV typ. (Iout = 4 mA)
● TTL, DTL, ECL, MOS, CMOS compatible outputs
● Automotive qualification
APPLICATIONS
● Level shifters● Sampling circuits
● Peak & zero crossing detectors
● Threshold detectors
● Automotive
