CJMCU-1118 ADS1118 16-Bit ADC with Integrated MUX PGA Temperature Sensor Oscillator and Reference
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 integrated voltage reference and oscillator. Data are 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). A programmable gain amplifier (PGA) is integrated in the ADS1118 that offers input ranges from as low as ±256 mV up to the supply rails, allowing both large and small signals to be measured with high resolution. The ADS1118 also features an input multiplexer (MUX) that provides two differential or four single-ended inputs. The
ADS1118 can also function as a high-accuracy temperature sensor. This temperature sensor can be used for system-level temperature monitoring or cold junction compensation for thermocouples.
The ADS1118 operates either in continuous conversion mode or a single-shot mode that automatically powers down after a conversion. Single-shot mode significantly reduces current consumption during idle periods. The ADS1118 is specified from –40°C to +125°C.
