这USERA ????指南描述的特征，操作和使用PGA309EVM -USB评估模块（ EVM ）的。 This userâs guide describes the characteristics, operation, and use of the PGA309EVM-USB evaluation module EVM.
The is an evaluation module, a test platform for the PGA309 programmable sensor conditioner. The evaluation module consists of two key hardware boards a PGA309 test board and USB DAQ Platform. The PGA309 test board contains the PGA309, terminal strips for external connections, several jumpers for device configuration, and support circuitry. The PGA309 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 PGA309. 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 PGA309. It provides a block diagram and register based description of the device
