8 Detailed Description

8.1 Overview

The LF353 device is a JFET-input operational amplifier with low input bias and offset currents and fast slew rate. Each amplifier features JFET inputs (for high input impedance) coupled with bipolar output stages integrated on a single monolithic chip. The output is protected against shorts due to the resistive 200-Ω output impedance.

8.3 Feature Description

8.3.1 Slew Rate

The slew rate is the rate at which an operational amplifier can change its output when there is a change on the input. These devices have a 13-V/μs slew rate.

8.4 Device Functional Modes

These devices are powered on when the supply is connected. This device can be operated as a single-supply operational amplifier or dual-supply amplifier depending on the application.
