Product Description
INA146UA Integrated Circuit Chip High-Voltage Programmable Gain Difference Amplifier
The INA146UA is a precision difference amplifier designed to accurately attenuate high differential voltages and reject high common-mode voltages for compatibility with common signal processing voltage levels. Its high-voltage capability provides inherent input protection, while the input common-mode range extends beyond both supply rails, making it an excellent choice for both single and dual supply applications.
