LM2903 is a low-power dual voltage comparator produced by ST company. It features a wide supply voltage range, low input bias current, low output saturation voltage, and TTL, DTL, ECL, MOS, and CMOS compatible outputs.
The LM2903 is a low-power dual voltage comparator designed to operate from a single supply over a wide range of voltages or split power supplies. It features a unique characteristic where the input common-mode voltage range includes the negative rail even when operated from a single supply. The device consists of two independent comparators with TTL, DTL, ECL, MOS, and CMOS compatible outputs.
| Supply voltage range | +2 V to +36 V or ±1 V to ±18 V |
|---|---|
| Supply current | 0.4 mA |
| Input bias current | 25 nA typ. |
| Input offset current | ±5 nA typ. |
| Output saturation voltage | 250 mV typ. |
| Operating temperature range | -40 to +125 °C |
The device supports a wide single supply voltage range from +2 V to +36 V or dual supplies from ±1 V to ±18 V.
No, the input common-mode voltage range includes the negative rail even when operated from a single power supply voltage.
The outputs are compatible with TTL, DTL, ECL, MOS, and CMOS logic families.
