Texas Instruments TLC3578EVM - Manual

1-1 EVM Overview EVM Overview Each evaluation board is based on the equivalent ADC. All ADCs use asynchronous serial interface which can be simply interfaced to many micro-controllers using the SPI protocol. Each EVM also incorporates a stable voltage reference, and operationalamplifier to ensure a ...
