General Description
Using patent pending new circuit topologies, the
LM6142/44 provides new levelsof performancein applica-
tions wherelow voltage suppliesor power limitations previ-
ously made compromise necessary. Operatingon supplies 1.8Vto over 24V,the LM6142/44isan excellent choice
for battery operated systems, portable instrumentationand
others.
The greater than rail-to-rail input voltage range eliminates
concern over exceedingthe common-mode voltage range.
The rail-to-rail output swing providesthe maximum possible
dynamic rangeatthe output. Thisis particularly important
when operatingonlow supply voltages.
High gain-bandwidth with 650 mA/Amplifier supply current
opens new battery powered applications where previous
higher power consumption reduced batterylifeto unaccept-
able levels.The abilityto drive large capacitive loads with-
out oscillating functionally removesthis common problem.
FeaturesAtVSe5V.Typ unless noted. Rail-to-rail input CMVR b0.25Vto 5.25V Rail-to-rail output swing 0.005Vto 4.995V Wide gain-bandwidth:17 MHzat50 kHz (typ) Slew rate:
