FEATURES  
DESCRIPTION  
The LF147 is a low cost, high speed quad JFET input  
operational amplifier with an internally trimmed input  
offset voltage ( BI-FET II™ technology). The device  
requires a low supply current and yet maintains a  
large gain bandwidth product and a fast slew rate. In  
addition, well matched high voltage JFET input  
devices provide very low input bias and offset  
currents. The LF147 is pin compatible with the  
standard LM148. This feature allows designers to  
immediately upgrade the overall performance of  
existing LF148 and LM124 designs.

Internally Trimmed Offset Voltage: 5 mV max  
Low Input Bias Current: 50 pA  
Low Input Noise Current: 0.01 pA/Hz  
Wide Gain Bandwidth: 4 MHz  
High Slew Rate: 13 V/μs  
Low Supply Current: 7.2 mA  
High Input Impedance: 1012Ω  
Low Total Harmonic Distortion: 0.02%  
Low 1/f Noise Corner: 50 Hz  
The LF147 may be used in applications such as high  
speed integrators, fast D/A converters, sample-and-  
hold circuits and many other circuits requiring low  
input offset voltage, low input bias current, high input  
impedance, high slew rate and wide bandwidth. The  
device has low noise and offset voltage drift.  
Fast Settling Time to 0.01%: 2 μs
