The PGA308EVM key hardware consists of two boards, PGA308 test board and USB DAQ platform. The PGA308 test board contains the PGA308, a programmable analog sensor signal conditioner. The analog signal path amplifies the sensor signal and provides digital calibration for offset and gain. The PGA308 test board can be used to fully test your design before prototyping it. The USB DAQ platform contains an 8052 microcontroller with a built in USB interface. The microcontroller generates the one wire signals necessary to communicate with the PGA308. The USB DAQ platform also contains, a 3V/5V programmable linear regulator, a switch for power control, general purpose digital I/O, DAC outputs, and A/D inputs. The software is windows based graphical software allows the user to communicate with and configure the PGA308. It provides a block diagram and register based description of the device.
● Flexible hardware allows for full testing of prototype
