PGA309EVM - USB密钥的硬件包括两块电路板， PGA309测试板和USB DAQ平台。该PGA309测试板包含PGA309 ，端子排的外部连接，多个跳线用于设备配置和支持电路。DescriptionThe PGA309EVM-USB key hardware consists of two boards, 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. The auto-calibration feature allows full calibration over temperature for a bridge sensor. A built in sensor emulator allows you to calibrate using an emulated sensor before connecting your real world sensor. Sensor emulation simplifies the learning and testing process for your sensor module. Features
