LM6142/LM6144
17 MHz Rail-to-Rail Input-Output Operational Amplifiers
General Description
Using patent pending new circuit topologies, the LM6142/
LM6144 provides new levels of performance in applications
where low voltage supplies or power limitations previously
made compromise necessary. Operating on supplies of 1.8V
to over 24V, the LM6142/LM6144 is an excellent choice for
battery operated systems, portable instrumentation and oth-
ers.
The greater than rail-to-rail input voltage range eliminates
concern over exceeding the common-mode voltage range.
The rail-to-rail output swing provides the maximum possible
dynamic range at the output. This is particularly important
when operating on low supply voltages.
High gain-bandwidth with 650µA/Amplifier supply current
opens new battery powered applications where previous
higher power consumption reduced battery life to unaccept-
able levels. The ability to drive large capacitive loads without
oscillating functionally removes this common problem.
