Analog Devices AD7192 Electronic Scale Circuit Application Note
The document details a reference circuit for an electronic scale system centered around the AD7192, a 24-bit sigma-delta analog-to-digital converter (ADC) with an integrated programmable gain amplifier (PGA). The design utilizes two ADP3303 low-dropout linear regulators to provide clean 5V and 3.3V power supplies for the load cell sensor and microcontroller interface, respectively.
