LR074A/E

LOW NOISE J-FET QUAD

OPERATIONAL AMPLIFIERS

DESCRIPTION

The

LR074/E is a high speed J-FET input quad

operational amplifiers incorporating well matched,

high voltage J-FET and bipolar transistors in a

monolithic integrated circuit.

The device features high slew rates, low input

bias and offset currents , and low offset voltage

temperature coefficient.

FEATURES

* Wide common-mode and differential voltage range

* Low input bias and offset current

* Output short-circuit protection

* High input impedance J-FET input stage

* Low harmonic distortion:0.01%(typ)

* Internal frequency compensation
