LF444CN

The LF444 quad low power operational amplifier 23? ? Supply Current of a LM148: 200 ?A/Amplifier
provides many of the same AC characteristics as the (max)
industry standard LM148 while greatly improving the
? Low Input Bias Current: 50 pA (max) DC characteristics of the LM148. The amplifier has
? High Gain Bandwidth: 1 MHz the same bandwidth, slew rate, and gain (10 k? load)
as the LM148 and only draws one fourth the supply ? High Slew Rate: 1 V/?s
current of the LM148. In addition the well matched
? Low Noise Voltage for Low Power 35 nV/?Hz high voltage JFET input devices of the LF444 reduce
? Low Input Noise Current 0.01 pA/?Hz the input bias and offset currents by a factor of
? High Input Impedance: 1012? 10,000 over the LM148. The LF444 also has a very
low equivalent input noise voltage for a low power
? High Gain: 50k (min) amplifier.
