The nutrition scale is mainly composed of an ADC chip, a pressure sensor, and a main control chip. The main functions include weighing, overload prompts, automatic zeroing, tare weighing, and low-pressure alarms. The value is accurate to 0.1 g.

CSU1182, CSU18P88, and CSU18M88 have built-in ADCs and MCUs. Thus, the communication between the MCU and the ADC is done within the chip, mitigating the influence of the external environment on ADCs. The reliability is higher than the application system based on a single ADC chip. Furthermore, the increased integration ensures superior cost performance. The integrated regulated power supply is convenient for powering the sensor.
