DDC264EVM

Оценочный модуль для АЦП.

The DDC264EVM provides an easy to use platform for evaluating the DDC264 device. The DDC264 is a 20bit, 64 channel, current input analog to digital (A/D) converter. It combines both current to voltage and A/D conversion so that 64 separate low level current output devices, such as photodiodes, can be directly connected to its inputs and digitized. For each of the 64 inputs, the DDC264 uses the proven dual switched integrator front end. This configuration allows for continuous current integration, while one integrator is being digitized by the onboard A/D converter, the other is integrating the input current. This architecture provides both a very stable offset and a loss less collection of the input current. Adjustable integration times range from 160µs to 1sec. The DDC264 has a serial interface designed for daisy-chaining in multi-device systems. Simply connect the output of one device to the input of the next to create the chain.
