LM6142 Dual and LM6144 Quad
High Speed/Low Power 17 MHz Rail-to-Rail Input-Output
Operational Amplifiers

General Description

Using patent pending new circuit topologies, the LM6142/44
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 LM6142/44 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 650 µA/Amplifier supply current
opens new battery powered applications where previous
higher power consumption reduced battery life to unaccept­able levels. Theabilityto drive large capacitive loads without
oscillating functionally removes this common problem.
