Overview
This product, BMH23M002, is a 24-bit ADC module featuring the built-in 24-bit ADC IC BH45B1525. It can be used with sensors based on the Wheatstone bridge principle (e.g., load cells using this principle) and allows reading of the AD value via I2C or SPI interface.
Features
ADC resolution: 24-bit, maximum ENOB (Effective Number of Bits): 22.8
Analog signal input interfaces:
♦ Wheatstone bridge sensor interface × 1 (AVDD, AN0, AN1, GND)
♦ Analog signal input interface × 1 (AVDD, AN2, AN3, GND)
Communication interfaces:
