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. FEATURES ? 100SPS Data Rate (High-Speed Mode) ? Single-Cycle Settling ? Easy Conversion Control with START Pin ? Automatic Shutdown ? Low Noise: 4μVRMS Noise (High-Resolution Mode) ? Input Multiplexer with Two Differential Channels (ADS1226) ? Voltage Reference Supports Ratiometric Measurements ? Self-Calibrating ? Simple Read-Only 2-Wire Serial Interface ? Internal High-Impedance Input Buffer ? Internal Temperature Sensor ? Internal Oscillator ? Low-Power: 1mW While Operating, < 1μA During Shutdown ? Analog and Digital Supplies: 2.7V to 5.5V APPLICATIONS ? Hand-Held Instrumentation ? Portable Medical Equipment ? Industrial Process Control |
