The ADS1244 is a 24-bit, delta-sigma Analog-to-Digital (A/D) converter. It offers excellent performance and very low power in an MSOP-10 package and is well suited for demanding high-resolution measurements, especially in portable and other space- and power-constrained systems.
A 3rd-order delta-sigma modulator and digital filter form the basis of the A/D converter. The analog modulator has a ±5V differential input range. The digital filter rejects both 50Hz and 60Hz signals, completely settles in one cycle, and outputs data at 15 samples per second.
A simple, 2-wire serial interface provides all the necessary control. Data retrieval, self-calibration, and Sleep Mode are handled with a few simple waveforms.
