Description and Introduction

Low Power, Single-Supply, Rail-To-Rail Operational Amplifiers--MicroAmplifier Series The **OPA345UA** is a precision operational amplifier (op-amp) designed for high-performance applications requiring low power consumption and excellent accuracy. Manufactured in a compact **SOT-23-5** package, this op-amp is well-suited for portable and battery-powered devices where space and efficiency are critical.  

Featuring a **rail-to-rail input and output** capability, the OPA345UA ensures optimal signal integrity even at low supply voltages, making it ideal for sensor interfaces, data acquisition systems, and medical instrumentation. Its low **quiescent current (50 µA typical)** minimizes power drain, extending battery life in wireless and IoT applications.  

With a **gain bandwidth product of 1 MHz** and a low **input offset voltage (500 µV max)**, the OPA345UA delivers stable and precise amplification for DC and low-frequency signals. Additionally, its high **common-mode rejection ratio (CMRR)** and **power-supply rejection ratio (PSRR)** enhance performance in noisy environments.  

Engineers favor the OPA345UA for its reliability in **temperature ranges from -40°C to +125°C**, ensuring consistent operation in harsh conditions. Whether used in industrial controls, consumer electronics, or automotive systems, this op-amp provides a robust solution for analog signal conditioning with minimal power overhead.  

For applications demanding precision, efficiency, and compact design, the OPA345UA stands as a dependable choice.
