ADS1244 Low-Power/ 24-Bit ANALOG-TO-DIGITAL CONVERTER

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 co.
