⁄ supply current of a LM148: 200 µA/Amplifier (max)  
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 kload) 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.  
n Low input bias current: 50 pA (max)  
n High gain bandwidth: 1 MHz  
n High slew rate: 1 V/µs  
n Low noise voltage for low power  
n Low input noise current  
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.
