The ADS833xEVM features the ADS8331 or ADS8332 analog to digital converter. The EVM provides a quick and easy way to evaluate the functionality and performance of this low power, high resolution, 16-bit Analog to Digital Converter (ADC). The EVM provides a serial interface header to easily attach to any host microprocessor or TI DSP base system. An OPA211 buffer amplifier is onboard and can be added into the signal path to drive the ADC by simply changing a jumper setting. By default, the ADS833xEVM is designed to operate with an onboard 4.096V reference (REF5040), but can be easily modified to use an external reference source. The REF5040 is pin compatible with the REF50xx family allowing a wide variety of reference values. The reference voltage signal has the option to be buffered through an OPA350 before connecting to the ADC.
