Ordering Information
LM6142QML
17 MHz Rail-to-Rail Input-Output Operational Amplifiers
General Description
Using patented new circuit topologies, the LM6142 provides
new levels of performance in applications where low voltage
supplies or power limitations previously made compromise
necessary. Operating on supplies of 2.7V to over 24V, the
LM6142 is an excellent choice for battery operated systems,
portable instrumentation and others.
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.
