Description and Introduction

LOW POWER, SINGLE-SUPPLY, RAIL-TO-RAIL OPERATIONAL AMPLIFIERS MicroAmplifier Series # Introduction to the OPA345 Operational Amplifier  

The OPA345 is a high-performance, low-power operational amplifier (op-amp) designed for precision applications in portable and battery-powered systems. With rail-to-rail input and output capabilities, it ensures optimal signal integrity even at low supply voltages, making it ideal for sensor interfaces, data acquisition, and signal conditioning circuits.  

Operating from a single supply voltage as low as 2.5V, the OPA345 delivers excellent DC precision with low offset voltage and drift, enhancing measurement accuracy. Its low quiescent current (typically 750µA) minimizes power consumption, extending battery life in portable devices. Additionally, the op-amp features a wide bandwidth and fast settling time, supporting both DC and AC applications.  

The OPA345 is available in compact packages, including SOT23 and SC70, making it suitable for space-constrained designs. Its robust performance, combined with low noise and distortion, ensures reliable operation in medical instruments, industrial controls, and consumer electronics.  

Engineers value the OPA345 for its balance of precision, power efficiency, and versatility, making it a preferred choice for demanding analog signal processing tasks. Whether amplifying weak sensor signals or driving analog-to-digital converters, this op-amp delivers consistent performance across a range of operating conditions.
