LF442CN
Dual Low Power JFET Input Operational Amplifier
LF442
Dual Low Power JFET Input Operational Amplifier
General DescriptionThe LF442 dual low power operational amplifiers provide
manyof the same AC characteristicsas the industry stan-
dard LM1458 while greatly improvingthe DC characteristics the LM1458. The amplifiers have the same bandwidth,
slew rate, and gain (10kΩ load)as the LM1458 and only
draw one tenththe supply currentofthe LM1458.In addition
the well matched high voltage JFET input devicesof the
LF442 reducethe input bias and offset currentsbya factorof
10,000 over the LM1458.A combinationof careful layout
design andinternal trimming guarantees verylow input offset
voltage and voltage drift. The LF442 also hasa very low
equivalent input noise voltagefora low power amplifier.
The LF442ispin compatible with the LM1458 allowingan
immediate10 times reductionin power drainin many appli-
cations. The LF442 shouldbe used where low power dissi-
pation and good electrical characteristicsare the major con-
siderations.
