Description and Introduction

1 uA, Rail-to-Rail, CMOS Operational Amplifiers # Introduction to the OPA349SA/250 Operational Amplifier  

The OPA349SA/250 is a precision operational amplifier (op-amp) designed for low-voltage, low-power applications. With a wide supply voltage range of 1.8V to 5.5V, this op-amp is well-suited for battery-powered devices, portable instrumentation, and sensor interfaces.  

Key features of the OPA349SA/250 include ultra-low quiescent current (typically 25µA), making it ideal for energy-efficient designs. It offers rail-to-rail input and output operation, ensuring maximum dynamic range in signal processing applications. Additionally, its high gain bandwidth (350kHz) and low offset voltage (3mV max) contribute to accurate amplification in precision circuits.  

The device is available in a small SOT-23-5 package, enabling compact PCB layouts. Its robust performance, combined with low noise and minimal power consumption, makes it a reliable choice for medical devices, industrial controls, and consumer electronics.  

Engineers selecting the OPA349SA/250 benefit from its stable operation across temperature variations and its ability to drive capacitive loads without oscillation. Whether used in signal conditioning, filtering, or buffering applications, this op-amp delivers consistent performance in space- and power-constrained designs.
