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
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 unacceptable levels. The ability to drive
large capacitive loads without oscillating functionally
removes this common problem.
