DC590B Datasheet PDF - Linear Technology

DESCRIPTION
Demonstration circuit 590B is a USB-based controller with generic Serial Peripheral Interface (SPI) and Inter Integrated Circuit (I2C™) ports. It is designed to mate with Linear Technology’s family of QuickEval™ demonstration boards. The demo board is fully isolated from the host PC’s ground, and in many cases no external power source is required. The evaluation software automatically detects which demo board is connected and loads the appropriate control screen.
The QuickEval system provides a quick and easy way to evaluate the performance of a wide variety of Linear Technology’s products, including ADCs, DACs, SMBus power control products, and many others.
