LF444 Quad Low Power JFET Input Operational Amplifier
May 1998
LF444
Quad Low Power JFET Input Operational Amplifier
General Description
The LF444 quad low power operational amplifier provides
many of the same AC characteristics as the industry stan-
dard LM148 while greatly improving the DC characteristics
of the LM148. The amplifier has the same bandwidth, slew
rate, and gain (10 k鈩?load) as the LM148 and only draws
one fourth the supply current of the LM148. In addition the
well matched high voltage JFET input devices of the LF444
reduce the input bias and offset currents by a factor of
10,000 over the LM148. The LF444 also has a very low
equivalent input noise voltage for a low power amplifier.
The LF444 is pin compatible with the LM148 allowing an im-
mediate 4 times reduction in power drain in many applica-
tions. The LF444 should be used wherever low power dissi-
pation and good electrical characteristics are the major
considerations.
