概要
Description
This amplifier operates with a dual supply ranging from ±2.5V to ±15V or a single supply from 5V to 30V, making it versatile for different power environments. It has a low input bias current, ensuring minimal error in the presence of high-impedance sources. With its low offset voltage and low drift over temperature, the LT1990CS8#PBF is ideal for precision applications such as data acquisition systems, industrial process controls, and sensor interfaces. The "PBF" suffix indicates that the device is lead-free and RoHS compliant, aligning with environmental regulations.
