Description and Introduction
Low Power, Single-Supply, Rail-To-Rail Operational Amplifiers MicroAmplifier(TM) Series 8-SOIC -40 to 85 The **OPA345UAG4** is a high-performance, low-power operational amplifier (op-amp) designed for precision applications in portable and battery-powered systems. Manufactured in a compact **SOT-23-5** package, this op-amp delivers excellent accuracy and efficiency, making it suitable for sensor interfaces, medical devices, and portable instrumentation.  
With a supply voltage range of **1.8V to 5.5V**, the OPA345UAG4 operates efficiently in low-voltage environments while maintaining a low quiescent current of **600µA (typical)**. Its rail-to-rail input and output capabilities ensure maximum signal integrity, even at reduced supply voltages. Additionally, the device features a high gain bandwidth of **1MHz** and a low offset voltage of **±0.5mV (max)**, enhancing its precision in signal conditioning tasks.   The OPA345UAG4 also includes built-in EMI filtering, reducing susceptibility to electromagnetic interference—an essential feature for sensitive analog circuits. Its robust design ensures stable performance across industrial temperature ranges (**-40°C to +125°C**), making it reliable for harsh environments.   Engineers favor this op-amp for its balance of power efficiency, precision, and compact form factor, making it an ideal choice for space-constrained and energy-sensitive applications. Whether used in data acquisition systems or portable medical monitors, the OPA345UAG4 provides dependable performance with minimal power consumption. |
