The ADS1118 is a precision analog-to-digital converter (ADC) with 16 bits of resolution offered in an ultra-small, leadless QFN-10 package or an MSOP-10 package. The ADS1118 is designed with precision, power, and ease of implementation in mind. The ADS1118 features an onboard reference and oscillator. Data are transferred via a serial peripheral interface (SPI). The ADS1118 operates from a single power supply ranging from 2V to 5.5V.
