ADS8318 Analog-to-Digital Converters Texas Instruments ADS8318 Analog-to-Digital Converters (ADC) are designed to target existing ADI MSOP-10 sockets. The TI device includes a 16-bit capacitor-based SAR ADC with an inherent sample and offers an SPI-compatible serial interface to minimize board space and simplify connectivity to the host device. The ADS8318 has a single differential input and requires a differential signal path for maximum performance.
