ADS1118 Ultra-Small Precision ADC

Texas Instruments' smallest fully-integrated ADC and temperature sensor

Texas Instruments ADS1118 Ultra-Small Precision ADC Texas Instruments' ADS1118 is a precision analog-to-digital converter (ADC) with 16 bits of resolution offered in an ultra-small, leadless QFN-10 package. The ADS1118 is designed with precision, power, and ease of implementation in mind. The ADS1118 features an onboard reference and oscillator. Data is transferred via a serial peripheral interface (SPI). The ADS1118 operates from a single power supply ranging from 2.0 V to 5.5 V. The ADS1118 can perform conversions at rates up to 860 samples per second (SPS). An onboard programmable gain amplifier (PGA) is available on the ADS1118 that offers input ranges from the supply to as low as ±256 mV.   ADS1118 Datasheet
