ADS1225 Datasheet PDF - Burr Brown

DESCRIPTION

●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.
