Description
The APO245 device is a low-cost, high-voltage, high-current, wide band and high gain operational amplifier that is designed to high performed audio applications. The APO245 is a direct replace of API2520, 990Enh or FV600 devices in the most representative applications.
This device provides excellent low-level signal accuracy and high-output voltage and current.
The APO245 operates with a large range of voltage supply for design flexibility.
The APO245 is implemented with high-quality discrete components.
The APO245 device is available in traditional package similar to API2520.
