TL082

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

Features

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 A_V10,:

0.02%

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.

R_L10k, V_O20 Vp − p,

BW 20 Hz−20 kHz

n Low 1/f noise corner: 50 Hz

n Fast settling time to 0.01%: 2 µs
