Description and Introduction
1 uA, Rail-to-Rail, CMOS Operational Amplifiers 5-SC70 # Introduction to the OPA349SA/250G4 Operational Amplifier  
The **OPA349SA/250G4** is a high-performance, low-power operational amplifier (op-amp) designed for precision applications. Manufactured by Texas Instruments, this component is part of the OPA349 series, known for its ultra-low quiescent current and rail-to-rail input/output capabilities.   Operating with a supply voltage range of **1.8V to 5.5V**, the OPA349SA/250G4 is ideal for battery-powered devices, portable instrumentation, and sensor interfaces. Its low power consumption—drawing just **14µA per channel—**extends battery life in energy-sensitive applications. Additionally, the op-amp features a **rail-to-rail input and output swing**, ensuring maximum signal integrity even at low voltages.   The **OPA349SA/250G4** offers excellent DC precision with low offset voltage and drift, making it suitable for precision signal conditioning. Its robust design includes EMI filtering, reducing susceptibility to interference in noisy environments. Available in a **small-outline SOT-23-5 package**, it is well-suited for space-constrained PCB layouts.   Applications for this op-amp include **medical devices, IoT sensors, handheld test equipment, and low-power data acquisition systems**. With its combination of low power, precision, and compact form factor, the OPA349SA/250G4 is a reliable choice for engineers designing efficient, high-performance circuits. |
