The STMicroelectronics LM2903 Low Power Dual Voltage Comparator consists of two independent low power voltage comparators specifically designed to operate from a single source over a wide range of voltages. Operation from split power supplies is also possible. The device also has a unique feature in that the input common mode voltage range includes the negative rail, although operated from a single supply voltage.
Characteristics:
- Wide voltage range from single or dual supply voltages +2V to +36V or ±1V to ±18V
- Low supply current (0.4mA) independent of 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.) (I Ó = 4mA)
- Differential input voltage range equal to supply voltage
- Outputs compatible with TTL, DTL, ECL, MOS, CMOS
- Automotive qualification
