LM392

LM392 Low Power Operational Amplifier and Comparator The LM392 contains two functions: an op amp and a comparator. Both devices can operate on single−supply power and both have a common−mode range down to ground. Operation from split power supplies is also possible. Low power−supply current is independent of the supply voltage level. The output of the comparator interfaces directly with either TTL or CMOS logic. Low quiescent current makes the LM392 ideal for portable equipment.
