Feature: JFET-Input Operational Amplifier
April 1998  
Wide Bandwidth Dual JFET Input Operational Amplifier  
General Description  
These devices are low cost, high speed, dual JFET input op-  
erational amplifiers with an internally trimmed input offset  
n Internally trimmed offset voltage: 15 mV  
n Low input bias current: 50 pA  
voltage (BI-FET II technology). They require low supply  
n Low input noise voltage: 16nV/ Hz  
current yet maintain a large gain bandwidth product and fast  
slew rate. In addition, well matched high voltage JFET input  
devices provide very low input bias and offset currents. The  
TL082 is pin compatible with the standard LM1558 allowing  
designers to immediately upgrade the overall performance of  
existing LM1558 and most LM358 designs.  
n Low input noise current: 0.01 pA/ Hz  
n Wide gain bandwidth: 4 MHz  
n High slew rate: 13 V/µs  
n Low supply current: 3.6 mA  
n High input impedance: 1012Ω  
n Low total harmonic distortion AV 10,:  
These amplifiers may be used in applications such as high  
speed integrators, fast D/A converters, sample and hold cir-  
cuits and many other circuits requiring low input offset volt-  
age, low input bias current, high input impedance, high slew  
rate and wide bandwidth. The devices also exhibit low noise  
and offset voltage drift.  
RL 10k, VO 20 Vp − p,  
BW 20 Hz−20 kHz  
n Low 1/f noise corner: 50 Hz  
n Fast settling time to 0.01%: 2 µs
