ADS1225IRGVTG4

模数转换器 - ADC 24-Bit 100SPS ADC

DESCRIPON

The ADS1225 and ADS1226 are 24-bit delta-sigma analog-to-digital A/D converters. They offer

excellent performance, ease-of-use, and low power in a small 4mm × 4mm QFN package and are

well-suited for demanding high-resolution measurements, especially in portable and other space-saving and power-constrained applications.
