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.
The ADS1244 is a 24-bit, delta-sigma analog-to-digital converter designed for high-resolution measurements in portable and space-constrained systems. It utilizes a 3rd-order delta-sigma modulator and digital filter to achieve excellent performance with very low power consumption in an MSOP-10 package.
The device features a simple 2-wire serial interface for control, including data retrieval, self-calibration, and sleep mode. It supports analog supplies from 2.5V to 5.25V and digital supplies from 1.8V to 3.6V, with typical power consumption of less than 270uW. The converter is well-suited for applications such as hand-held instrumentation, portable medical equipment, and industrial process control.
