LT1116CN8#PBF

LT1116CN8#PBF is an ultra fast comparator designed for sensing signals near the negative supply. The input common mode range extends from 2.5V below the positive supply down to the negative supply rail. Like the LT1016, this comparator is specifically designed to interface directly to TTL logic with complementary outputs. The comparator may operate from either a single 5V supply or dual ±5V supplies. Tight offset voltage specifications and high gain allows the device to be used in precision applications. It is designed for improved speed and stability for a wide range of operating conditions. It is used in application applications such as high speed A/D converters, zero crossing detectors, current sense for switching regulators, extended range V to F converters, fast pulse height/width discriminators, high speed triggers, line receivers, high speed sampling circuits.

• Input common mode extends to negative supply
• No minimum input slew rate requirement
