Key Features
- No latency, filter settling, or redundant data associated with the conversion cycle, ensuring a one-to-one correspondence between the conversion and the output data.
- On-chip highly accurate oscillator eliminates the need for external frequency setting components such as crystals or oscillators.
- Continuous offset and full-scale calibrations every conversion cycle, providing extreme stability of offset and full-scale readings with respect to time, supply voltage change, and temperature drift.
- Low power consumption with reduced power in sleep state when CS is HIGH.
- Configurable for better than 110dB rejection at 50Hz or 60Hz ±2%, or driven by an external oscillator for a user-defined rejection frequency in the range 1Hz to 120Hz.
