LF247DT ST Operational Amplifier | 14-SO | 4.5V-30V, 1.3MHz

Product Overview

The LF247DT from STMicroelectronics is a quad low-power JFET-input operational amplifier in a 14-SO package. It offers high input impedance, low input bias current, and low supply current, making it ideal for battery-powered and precision applications. The device operates from a single or dual supply voltage ranging from ±4.5V to ±15V (or 9V to 30V single supply). With a gain bandwidth product of 1.3 MHz and a slew rate of 1.6 V/µs, it provides adequate performance for general-purpose signal conditioning.
