Overview
The OPA2607, specifically the OPA2607SIRUGR, is a decompensated, general-purpose CMOS operational amplifier produced by Texas Instruments. This device is part of the OPAx607 family and is known for its low noise, wide bandwidth, and rail-to-rail output. It is optimized for low supply voltage operation and is suitable for a variety of applications requiring a balance between cost and performance.
The OPA2607 features high-impedance CMOS inputs, making it ideal for interfacing with sensors that have high output impedance, such as piezoelectric transducers. The device also includes a Power Down mode, which reduces the quiescent current to less than 1 µA, making it suitable for battery-powered portable applications.
