Product Details
The MAX903 is a high-speed, low-power,
single voltage comparator with differential analog inputs
and a TTL logic output. The analog input common mode
range includes the negative rail, allowing ground
sensing when powered from a single supply.
For newer designs the MAX9203 is recommended.
