AMC7823EVM

模拟监视&控制电路, 全功能评估板

The is a simple evaluation module designed for a quick and easy way to evaluate the functionality and performance of the 12bit resolution AMC device. The Built in ADC features an eight channel analog input with 200ksps sample rate. The AMC7823 also consists of eight independent 12bit resolution DACs with 2ms settling times. Although the AMC7823 has a Built in internal band-gap reference that is software selectable between 1.25V and 2.5V, an external reference source is provided. The internal 1.25V reference voltage is the default reference on power up, so the reference voltage should be set to the desired source and level, if necessary. The SPI serial interface of the AMC7823 can communicate with any host microprocessor capable of the SPI protocol and most DSP based systems.
