Renesas Electronics Smart Industrial Weight Scale Solution
Renesas Smart Industrial Weight Scale Solution utilizes the RA2A1 microcontroller by integrating high-precision analog functions, such as op amps, a 24-bit sigma-delta ADC, 16-bit ADCs, and DAC. Designers can simplify their design by eliminating external components, reducing overall system space and cost, thereby increasing system reliability.
Bridge transducers are used on most weight scales for precise measurements. The challenge with this implementation is that the output differential signal from the transducer is very diminutive and needs to be amplified before processing. For general MCU control systems, this typically involves using instrumentation amplifiers with high-accuracy ADCs and voltage references.
The integration of analog functions in a microcontroller offers interesting ways to create combined analog and digital functions that work together under full user control. Renesas Smart Industrial Weight Scale Solution provides an accurate method for sensing the transducer signal and measuring it with the RA2A1 MCU.
