The ADS1119IRTET With Analog to Digital Converters (ADC) is manufactured by Texas Instruments. It is a 16-bit, 1kSPS, 4-ch general-purpose delta-sigma ADC with I2C interface and external Vref inputs 16-WQFN -40 to 125. It is equipped with an internal reference, programmable gain amplifier andoscillator. It has 16-bit conversion resolution, a selectable input voltage range of 0-2.048V or 0-4.096V, 1,024 samples per second (sps) throughput rate, and an I2C/SMBus serial interface. It also features an automatic-calibration feature and programmable-gain amplifier, and is suitable for use in a variety of general-purpose, low-power applications. The ADS1119IRTET can operate from -40°C to 125°C ambient temperatures and is available in a 16-pin WQFN (Warm Quad Flat No-Lead) package.
