This document describes the features and characteristics of the LF147 - LF247 - LF347 series wideband quad J-FET operational amplifiers, including low power consumption, wide common-mode and differential voltage range, low input bias and offset currents, output short-circuit protection, high input impedance, internal frequency compensation, etc.
This document is a technical datasheet for the LF147, LF247, and LF347 series of wide bandwidth quad J-FET operational amplifiers manufactured by STMicroelectronics. These monolithic integrated circuits incorporate well-matched high voltage J-FET and bipolar transistors, offering features such as low input bias current, internal frequency compensation, and latch-up free operation.
The datasheet provides absolute maximum ratings, detailed electrical characteristics including supply voltage rejection ratio and slew rate, typical application circuit diagrams for audio distribution and bandpass filters, and mechanical package data for both 14-pin Plastic DIP and Plastic Micropackage (SO) formats.
