ADS1219 Precision Analog-to-Digital Converters

Texas Instruments ADS1219 Precision 24-Bit Analog-to-Digital Converters (ADCs) include all features necessary to implement the most common system monitoring functions, such as supply voltage, current, and temperature monitoring. The device features two differential or four single-ended inputs through a flexible input multiplexer (MUX), rail-to-rail input buffers, a programmable gain stage, a voltage reference, and an oscillator. The device includes buffers that allow high-impedance sources to be directly connected to the device. A gain stage follows the buffers, which provide selectable gains of 1 and 4. The ADS1219 can perform conversions at data rates as high as 1000 samples per second (SPS) with single-cycle settling. At 20SPS, the digital filter offers simultaneous 50Hz and 60Hz rejection for noisy industrial applications.
