Description and Introduction

1 uA, Rail-to-Rail, CMOS Operational Amplifiers The **OPA349NA/250** is a precision operational amplifier (op-amp) designed for low-voltage, low-power applications. With a supply voltage range of **1.8V to 5.5V**, it is well-suited for battery-powered devices, portable instrumentation, and sensor interfaces. The device features **rail-to-rail input and output operation**, ensuring maximum signal integrity even at low supply voltages.  

Key specifications include a **quiescent current of just 50µA**, making it ideal for power-sensitive designs. The OPA349NA/250 offers a **gain bandwidth product of 350kHz** and a low input offset voltage, ensuring accurate signal amplification in precision circuits. Its **high common-mode rejection ratio (CMRR)** minimizes noise interference, enhancing performance in challenging environments.  

Packaged in a **small-outline (SOIC) format**, the OPA349NA/250 is optimized for space-constrained applications. It is commonly used in **medical devices, handheld meters, and IoT sensors**, where efficiency and reliability are critical.  

Engineers value this op-amp for its **low power consumption, stable operation, and robust performance** across a wide temperature range. Whether amplifying weak sensor signals or driving analog-to-digital converters, the OPA349NA/250 delivers consistent results in demanding low-voltage systems.
