Frequently Asked Questions
What is the supply voltage range for OPA4350UA?
The OPA4350UA operates from a single supply voltage of 2.5 V to 5.5 V, or dual supplies of ±1.25 V to ±2.75 V, making it well suited for battery-powered and low-voltage systems.
What makes OPA4350UA suitable for precision signal conditioning?
The OPA4350UA features an ultra-low input bias current of 0.01 nA, a 66 dB minimum common-mode rejection ratio, and a 38 MHz gain-bandwidth product. These characteristics make it ideal for high-impedance sensor interfaces, photodiode amplifiers, and precision instrumentation applications.
Does OPA4350UA support rail-to-rail operation?
Yes. The OPA4350UA provides true rail-to-rail input and output swing on a single supply, allowing the output to drive signals across the full supply range. This is essential in low-voltage designs where maximum dynamic range is required.
What package is the OPA4350UA available in?
The OPA4350UA is offered in a 14-pin SOIC (Small Outline Integrated Circuit) package, which is compatible with standard PCB assembly processes and provides four independent op-amp channels in a compact footprint.
