LM2903B Overview
Representative LM2903B image (package may vary by manufacturer)
Description
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.
Key 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
