STMicroelectronics LM2901B

The LM2901B consists of four 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 single supply voltage operation, however operation from dual power supplies is also possible.

The B-grade version of the LM2901 comparators offers an increased maximum operating voltage of 40 V and improved electrical characteristics.

Features

• AEC-Q100 qualified
• Wide single supply voltage range or dual supplies +2 V to +36 V or ±1 V to ±18 V
• Very low supply current 1 mA (typ., all channels), 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. (I_O = 4 mA)
• Input voltage range can exceed the positive supply voltage
• TTL, DTL, ECL, MOS, CMOS compatible outputs

Applications

• Level shifters
• Sampling circuits
• Peak & zero crossing detectors
• Threshold detectors
• Automotive
