AD7303BN Overview
There is a 8-DIP (0.300, 7.62mm) package that includes this component. It is powered from a supply voltage of 3V. The Through Hole-slot on the development board allows you to attach the FPGA module. While operating, the operating temperature should be kept within a range of -40°C~105°C. As a space-saving measure, this FPGA model is contained within Tube. Total terminations are 8. In order to find related parts, you can use its base part number AD7303. Power is provided by a 3/5V battery that is included with the device. As far as the pin count is concerned, it has 8 pins.
