Measurement sensor IC
This product series is a SoC with built-in 24 bits ADC, programmable low-noise high-input impedance preamplifier, LED driver, and human body impedance measurement module. The maximum current of the LED driver is 14mA with selectable waveform duty cycle. The built-in sine wave generator and rectifier circuit supports a four-electrode, multi-frequency human body bioelectrical impedance measurement and analysis. It has a two-wire communication with Bluetooth or WiFi chip. C language can be used for programming.
