FEATURES  
DESCRIPTION  
The LF444 quad low power operational amplifier  
provides many of the same AC characteristics as the  
industry standard LM148 while greatly improving the  
DC characteristics of the LM148. The amplifier has  
the same bandwidth, slew rate, and gain (10 kΩ 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.  
23  
¼ Supply Current of a LM148: 200 μA/Amplifier  
(max)  
Low Input Bias Current: 50 pA (max)  
High Gain Bandwidth: 1 MHz  
High Slew Rate: 1 V/μs  
Low Noise Voltage for Low Power 35 nV/Hz  
Low Input Noise Current 0.01 pA/Hz  
High Input Impedance: 1012Ω  
High Gain: 50k (min)  
The LF444 is pin compatible with the LM148 allowing  
an immediate 4 times reduction in power drain in  
many applications. The LF444 should be used  
wherever low power dissipation and good electrical  
characteristics are the major considerations.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam  
during storage or handling to prevent electrostatic damage to the MOS gates.
