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
