STMicroelectronics LM2903 Low-Power Dual Voltage Comparator consists of two independent low-power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. The device also has a unique characteristic in that the input common-mode voltage range includes the negative rail even though operated from a single power supply voltage.
Features:
- Wide single supply voltage range or dual supplies +2V to +36V or ±1V to ±18V
- Low supply current (0.4mA) independent of the supply voltage (1mW/comparator at +5V)
- Low input bias current: 25nA (typ.)
- Low input offset current: ±5nA (typ.)
- Input common-mode voltage range includes negative rail
- Low output saturation voltage: 250mV (typ.) (IO = 4mA)
- Differential input voltage range equal to the supply voltage
- TTL, DTL, ECL, MOS, CMOS compatible outputs
- Automotive qualification
