Maxim Integrated's low power MAXREFDES82# reference design quickly calculates force and center of mass.
Design engineers can now rapidly evaluate and deploy new human-machine interface (HMI) devices using the MAXREFDES82# smart force sensor reference design from Maxim Integrated Products.
Typical weigh scales provide one dimension of information, downward force. The MAXREFDES82# reference design provides both downward force and center of mass, by collecting responses from four load cells using the MAX11254, a 24-bit, 6-channel analog-to-digital converter (ADC). This unique configuration, enabled by the highly integrated 24-bit ADC, provides second and third dimensions of information about whatever object presses upon it.
Key Advantages
