Key Solution Features

Optimized accuracy and performance
Low power for longer battery life
- Low supply voltage range 1.8 V to 3.6 V
- Ultra-low power consumption
- Five power-saving modes
- Ultra-fast wake-up from standby mode in less than 1µA

Configurable AFE for multiple sensor types
- Configurable AFE enables it to support multiple sensors with PGA integration.
- Designed to maximize dynamic range of ADC by removing dark current via level shifting and then providing high levels of amplification to the signal of interest
- Extremely low power means extra battery life and/or guarantees operation under the 4mA limit in 4-20 mA loops
MCU + RF SoC for configuration, calibration and communication
- Enables on-line or factory programmed configuration and calibration of the sensor
- Supports broadcast and peripheral mode BLE
