OPA4348AID

OPA4348AID Description

The OPA4348AID from Texas Instruments is a high-performance, CMOS-based quad operational amplifier designed for precision, low-power applications. Packaged in a 14-SOIC tube, this IC operates over a 2.1V to 5.5V supply range, making it ideal for battery-powered and portable devices. With an ultra-low input bias current of 0.5 pA and a 1 MHz gain bandwidth product, it delivers excellent signal fidelity and stability. The ROHS3-compliant device features four independent channels, each capable of sourcing 10 mA output current, and exhibits a low input offset voltage of 1 mV, ensuring accuracy in sensitive circuits.

OPA4348AID Features

• Low Power Consumption: Only 45 µA per channel (total 180 µA for quad), ideal for energy-efficient designs.
• Wide Supply Range: 2.1V to 5.5V supports both single and dual-supply configurations.
• High Precision: 0.5 pA input bias current and 1 mV offset voltage minimize errors in signal conditioning.
• Compact and Reliable: 14-SOIC package with MSL 2 (1 Year) moisture sensitivity ensures robustness in surface-mount applications.
• Low Noise: 0.5V/µs slew rate and CMOS architecture reduce distortion in high-impedance sensor interfaces.
