The ADS1245 is a 24-bit, delta-sigma analog-to-digital converter (ADC). 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 ADS1245 is a 24-bit, delta-sigma analog-to-digital converter (ADC) designed for demanding high-resolution measurements in portable and space-constrained systems. It features a high-impedance buffered input with a ±2.5V differential input range and operates from low-power supplies. The device includes simultaneous rejection of both 50Hz and 60Hz signals, single-cycle settling time, and self-calibration capabilities.
