Overview

The OPA348AIDBVR is a single-channel, low-power CMOS operational amplifier designed for cost-sensitive, battery-operated applications. It features rail-to-rail input and output capabilities while maintaining a very low supply current of 45uA. This device is optimized for low-voltage operation between 2.1V and 5.5V, making it ideal for modern portable electronics.

Why Choose This Part

The OPA348 provides an excellent balance between power consumption and speed, offering a 1MHz gain bandwidth product at only 45uA. Its rail-to-rail swing allows for maximum dynamic range on low-voltage supply rails. Furthermore, the 0.5pA input bias current minimizes errors in circuits with high source impedances.

Applications

Battery-Powered Instrumentation
Utilizing the 45uA supply current to extend battery life in handheld measurement tools and remote sensors.
Photodiode Preamplifiers
Leveraging the extremely low 0.5pA input bias current for high-impedance sensor signal conditioning.
Active Filtering
Implementing low-pass or band-pass filters in portable audio or signal processing stages with its 1MHz bandwidth.
Current Shunt Sensing
Monitoring current in power management circuits using the rail-to-rail input and output range.
