Description and Introduction

1µA, Rail-to-Rail, CMOS Operational Amplifiers The **OPA349UA** is a high-performance, low-power operational amplifier (op-amp) designed for precision applications in portable and battery-powered systems. Known for its ultra-low quiescent current of just 25 µA, this component is ideal for extending battery life in devices such as medical instruments, sensor interfaces, and handheld test equipment.  

Featuring rail-to-rail input and output operation, the OPA349UA ensures accurate signal amplification even at low supply voltages, making it suitable for single-supply designs. Its wide supply voltage range (1.8V to 5.5V) enhances versatility across various circuit configurations. Additionally, the op-amp offers excellent DC precision with low offset voltage and drift, contributing to reliable performance in measurement and control systems.  

The OPA349UA is housed in a compact **SOT-23-5** package, optimizing space in densely populated PCBs. Its robust design includes built-in EMI filtering, reducing susceptibility to interference in noisy environments. With a unity-gain stable architecture and fast settling time, this op-amp provides a balance of speed and stability for signal conditioning tasks.  

Engineers favor the OPA349UA for its combination of low power consumption, precision, and small footprint, making it a preferred choice for energy-sensitive and space-constrained applications.
